There are more proposals with renderings, scheduled to start construction between now and 2014! I just didn't dig them all up. many of the bigger projects, won't start construction until 2013 or 2014, so they will open around the same time as Union Station construction is complete. So more to come!


As far as the 12.1 mile lone, West Corridor LRT line under construction as part of FasTracks... Tracks are now all laid and a single LRT vehicle is being pulled along the entire route, to confirm clearences. The line is due to open for service, in early 2013:

Welcome to Inside FasTracks – a monthly e-update for key stakeholders and community leaders, designed to keep you informed about the progress of the Regional Transportation District’s FasTracks program, upcoming events and meetings, and most importantly, FasTracks news. Your issue of Inside FasTracks arrives the last Monday of each month.

Latest News
RTD Board Votes on Northwest Rail Plan, Annual Report to DRCOG
The RTD Board of Directors will take a formal vote at the March 27 regular Board meeting on the 2012 FasTracks Financial Plan, which will include their decision on how to move forward with the Northwest Rail Line.

Each year, RTD conducts an Annual Program Evaluation which updates all inputs into the FasTracks Financial Plan, including:
  • Sales and use tax forecasts
  • Construction inflation assumptions
  • Operations and maintenance (O&M) costs
  • Capital costs
The capital cost for the FasTracks program has increased from $6.8 billion in 2011 to $7.4 billion in year-of-expenditure dollars by 2022. This includes building Northwest Rail to Church Ranch and bus rapid transit (BRT) in the northwest area, but doesn’t include building rail from Church Ranch to Longmont. That final cost will be determined following future negotiations with BNSF Railway. Most of FasTracks is scheduled for completion by 2020, including the partially funded projects like I-225; North Metro; U.S. 36 BRT; and the Southwest, Southeast and Central Corridor Extensions. Northwest Rail to Church Ranch would be complete in the 2020-2022 timeframe.

On March 20, the Regional Transportation District (RTD) Board’s FasTracks Monitoring Committee endorsed the RTD staff’s hybrid option recommendation on how to proceed with the FasTracks Northwest Rail Line.

The current plan keeps the Northwest Rail Line to Longmont in the FasTracks program, but adds BRT service to address transit needs in the short-term until the full build out of the rail.
  • Commuter rail would be phased in incrementally while also implementing a bus rapid transit system
  • The Northwest Rail Line would be extended to Church Ranch Blvd. in Westminster by 2022
  • Bus rapid transit (BRT) would be provided by 2020
  • Funding is anticipated to be available to start construction and service on Northwest Rail from Church Ranch to Longmont in the 2028-2034 timeframe
  • Would not delay any of the other FasTracks projects
  • Hybrid plan is dependent on a successful 0.4 percent sales tax election
  • One of the benefits of moving forward with this plan is that it allows us to accommodate the immediate transit needs in the northwest area through bus rapid transit, while making the ultimate long-term investment in Northwest Rail as our cash flow allows and as transit needs grow.

First Rail Car Travels Along West Rail Line

The public saw the first light rail car travel along the West Rail Line on March 22 when RTD crews began initial clearance testing along the rail line.

Crews using a “unimog” (similar to a rail tugboat) pulled a light rail vehicle along the whole corridor beginning just south of the newly relocated Auraria West Station in downtown Denver.
This initial test confirms clearances between the vehicle and surrounding elements of the rail line including bridges, tunnels, sound walls, fencing, poles and station platforms along the alignment. Additional operations testing will continue intermittently until the West Rail Line opens in May 2013.

RTD Receives Unsolicited Proposal for I-225 Rail Line

RTD received a confidential unsolicited proposal for the I-225 Rail Line. The proposal was submitted by Kiewit Infrastructure Company, which led the design-build construction team on the Transportation Expansion (T-REX) project – a joint highway/light rail project of RTD and the Colorado Department of Transportation (CDOT). Kiewit is
currently constructing the transit improvements at Denver Union Station, which are nearly 60 percent complete.

RTD staff is evaluating the proposal consistent with the agency’s Unsolicited Proposals Policy. In early April, RTD will determine whether to pursue a competitive procurement process and release a Request for Proposals for competing proposals.

Over the past year, RTD has publicized the agency’s desire to seek out innovations to complete the FasTracks program as soon as possible, enhance customer experience and reduce the cost of operations. This was the premise behind RTD’s first industry forum “Transformation Through Transportation” on Sept. 27, 2011.

“We’ve been encouraging the industry to think outside the box and come up with innovative ways to invest in our projects and get them done sooner rather than later,” said RTD Board Chair Lee Kemp.

“As one of RTD’s main partners on the I-225 Line, the City of Aurora is very encouraged by this proposal, and supports any effort that will help bring light rail to our community as soon as possible,” said Aurora Mayor Steve Hogan.

Lakewood•Wadsworth Parking Structure Groundbreaking Event
RTD and Swinerton Builders will break ground on the Lakewood•Wadsworth Parking Structure Wed., April 11 at 10 a.m. The 1,000-car garage will open with the West Rail Line in May 2013. Parking for the groundbreaking event will be available on 14th Avenue, east of Wadsworth Boulevard. Light refreshments will be served. For more information please call 303.592.1122.

First FasTracks Commuter Rail Car Undergoes Squeeze Test
The steel shell for the first RTD FasTracks commuter rail car underwent a compression “squeeze” test for structural integrity at the Hyundai Rotem plant in Changwon, South Korea, on Feb. 28. The car body was subjected to 800,000 pounds of pressure, and preliminary data indicates the structure performed well and well within Federal Railroad Administration limits.

Denver Transit Partners, RTD’s concessionaire on the Eagle P3 commuter rail project, is obtaining 50 electric commuter rail cars from Hyundai Rotem. The shells are being manufactured in Korea and then shipped to a Hyundai plant in Philadelphia for outfitting and finishing. At least 60 percent of the vehicle by value will be made in America. The commuter rail vehicles will be used in RTD's East Rail Line to Denver International Airport, Gold Line to Arvada/Wheat Ridge and the Northwest Rail Line to south Westminster.

FastFacts
West Rail Line Progress
Final Track Installed on West Rail Line
  • The RTD FasTracks West Rail Line project team installed the final segment of track on the West Rail Line. Crews working just west of the Union Boulevard Tunnel completed the task of fully tying in the track for the whole rail line from Denver Union Station to the Jefferson County Government Center.
  • The West Rail Line encompasses more than 116,000 lineal feet of track. Using effective and cost-efficient construction methods, and state-of-the-art equipment, the 45-member crew successfully completed the track installation in an unprecedented 18 months.
Project Progress

Central Rail Extension
The project team is evaluating options for extending streetcars into downtown Denver with potential for funding beyond the FasTracks program.
The team is continuing coordination with stakeholders.

Commuter Rail Maintenance Facility
  • Building design is progressing on what will be a Leadership in Energy and Environmental Design certified facility.
  • One structure on the site has been demolished and utility relocations are underway.
  • The CRMF yard has reached 100 percent design level.
Denver Union Station
  • Work continues in the interior first half of the bus facility (light rail terminal to Wewatta Street). Crews will pour the slab for the pedestrian concourse to prepare for flooring installation. Wall framing for the pedestrian concourse is in progress.
  • Crews completed the base slab for the second half of the underground bus facility (Wewatta Street to west side of building). The bridges that support the commuter rail train tracks over the bus structure will take shape as abutments and columns are added.
  • Crews continue to install the concrete unit pavers in the plaza area. The placement of the pavers will be in progress for several more weeks.
  • Work on 16th Street between Wewatta and Wynkoop Streets will be complete on the north side and move to the south side in a few weeks. When the 16th Street Free Mall Ride buses move to the north side of 16th Street, pedestrian access will remain on the south side.
  • Multiple construction activities are in the works in front of the historic station; however, the building will remain open with a designated area for pedestrian access. On the north side, crews work on the construction of 18th Street and sidewalk, curb and gutter construction on Wynkoop Street In the south area, crews work on utilities and the reconstruction of 16th Street. Within the next month, cranes will be located in the front of DUS.
East Rail Line
  • Major utility and wall construction is wrapping up along one mile of the Coors Field parking lot, ahead of the start of the Colorado Rockies baseball season. Buttoned up in time for first pitch in April, the work in the parking lot will move into the alignment itself, away from the fans, during the baseball season.
  • Relocation of some of the Union Pacific Railroad freight track is underway, along with construction of new rail yards.
  • Building demolitions are continuing as properties are turned over to the contractor.
  • Relocation of gas, water and wastewater lines continues.
  • The long haul fiber optic cable relocation is nearly complete.
Gold Line
  • The first car shell for the commuter rail vehicles successfully underwent an 800,000-pound “squeeze” test for structural strength.
  • Property acquisition is underway.
  • The relocation of various utilities has begun. Over the next year, natural gas, water, wastewater and power lines will be relocated.
I-225 Rail Line
  • SEMA Construction Inc. was awarded the construction contract for the combined CDOT/RTD project and given a notice to proceed on March 12. A construction schedule will be finalized by the end of March.
  • The I-225 and North Metro Corridor teams are preparing a request for proposal procurement package for track and systems elements construction for each project.
North Metro Rail Line
  • The Final Design request for proposal was released March 15 with an anticipated notice to proceed in the third quarter of 2012.
  • The team continues moving forward to secure intergovernmental agreements, utility relocation agreements and right of way for segment one; meeting with local agencies, CDOT, railroads (UPRR & BNSF); and coordinating with stakeholders to discuss property impacts.
  • Appraisals for right of way on segment one will begin this summer.
  • Construction is estimated to begin in 2014 with train service for the first segment beginning in 2017.
Northwest Rail Line
  • Property acquisition, utility relocation of gas, water and wastewater lines, and demolition of several structures have begun along the first segment of the rail line to south Westminster.
  • The Eagle P3 project design team is incorporating City of Westminster-funded betterments at the Westminster Station.
  • On March 5, RTD staff recommended a hybrid plan that would keep the Northwest Rail Line to Longmont in the FasTracks plan, but would phase in commuter rail while implementing a bus rapid transit (BRT) system. Under this option, RTD would build rail to the Church Ranch Station in Westminster by 2022 and implement BRT by 2020. The BRT would help meet the mobility needs of residents in the area while the rail is built in incremental stages as funding becomes available.
Southeast Rail Extension
  • The Board approved a Locally Preferred Alternative for the project on February 21 and the team continues to work on an alternatives analysis/environmental assessment in anticipation of seeking federal funding for the project.
  • The team is continuing design coordination with project stakeholders.

  • CDOT, assisted by RTD staff, chose Ames/Granite Joint Venture team as the design-build contractor for the managed lanes to 88th Street (approximately 1.5 miles west of Interlocken/96th Street). The project is scheduled to begin this summer and wrap up by Dec. 31, 2014, which is ahead of schedule by about six months.
  • In February, the High-Performance Transportation Enterprise released a request for qualifications to extend the managed lanes to Table Mesa.
West Rail Line
  • Seven of the 12 traction-powered substations have been set.
  • Crews are finalizing track installation under the Union Tunnel.
  • Canopies and shelters are currently being set on top of the Wadsworth Bridge.
  • Drainage improvements will require the closure of Harlan Street between 11th and 13th Avenues for approximately the next two months.
  • Construction began on the Wadsworth parking structure with erosion control and grading. A public meeting was held on March 1 to update the community on both Wadsworth and Sheridan Structures.
  • The groundbreaking for the Lakewood•Wadsworth Parking Structure is scheduled for Wed., April 11 at 10 a.m.

East Corridor EMU Construction Update

Eagle P3 EMU Lines under construction:


Girders set on first bridge, on the East Corridor EMU rail line from Denver Union Station to Denver International Airport.
This is the first of 21 bridges to be constructed as part of the Eagle P3 (DBFOM) EMU rail lines.
These include the East Corridor EMU (22.8 Miles), North West Electrified Segment EMU (5.9 Miles) and the
Gold Line EMU (11.9 Miles). ROW acquisition, preparation and Utility relocation are underway on all three of these lines.
All three are scheduled to be operation between 2015 and 2016 (if not sooner, contractor hasn't ruled out ahead of schedule
completion, if everything goes smoothly).
This bridge over Broadway Avenue between Blake Street and 29th Street, is the first substantial construction to take place.

Here are the vehicle facts for the RTD Denver varient Silverliner V's to be used on all of Denver's EMU lines:

Quote:
The Eagle P3 Project will make use of commuter rail technology, rather than the current RTD light rail lines and vehicles. Commuter rail technology is designed with speed and distance in mind; the vehicles are built to travel longer distances and at faster speeds than light rail vehicles, with the commuter rail lines having fewer stations and stops than light rail lines. Although the commuter rail cars will be powered by electricity in a similar manner to the current RTD light rail vehicles, the electrical current will be delivered at a much higher voltage.

Hyundai Rotem USA will manufacture the Eagle P3 commuter rails vehicles and will subscribe to the Buy America Clause with at least 60% of the vehicles made in America.


Eagle P3 Commuter Rail Car Specifications:
  • Each railcar is 85 feet long
  • Railcar weight of 140,000 pounds
  • Runs in married pairs – two vehicles attached at once
  • Top speed of 79 mph
  • Seats 90 passengers per vehicle
  • Maximum number of 233 passengers per vehicle
  • 2 dedicated luggage storage racks per vehicle
  • 2 bicycle/multi-purpose storage racks
  • Overhead carry-on storage areas running the length of the vehicle
  • Level-boarding at all entrances – no stairs
  • Two ADA/handicapped seating areas per vehicle
  • LCD screens and overhead announcements giving
    real-time updates on current location and
    upcoming stations
And renderings of these EMU vehicles:

Well, I think most USA EMU's are capable of 100mph, including these Silverliner V's. However, Union Pacific opposed any passenger trains traveling in their freight ROW, traveling faster than 79mph (of the 22.8 miles long East Corridor, only less than 1.8 miles is actually inside Union Pacific ROW, but will not share any of their freight tracks). Also, while this line is vastly grade-separated from intersections (including all major intersections), there are still many small side streets which will have at-grade crossings.

I think to get FRA clearance for the trains actual maximum speed of 100mph, it would have been much more costly and these three EMU lines are already a $2.185 billion project.

Does Philly run their Silverliner V's at 100mph, or do they go with the 79mph speed limit?

But anyway, these Denver Silverliner V's do have an actual maximum speed of 100mph. That's not bad for FRA-Compliant EMU's. Maybe one day, they will upgrade portions of or all of the routes, to 100mph FRA standards.

Even at 79mph, that kind of speed is a VAST improvement over the 55mph freeway (which goes considerably slower than that during rush hour). Of course the multiple stops will slow the average speed slightly, but even with stops, this will still be by far the most convenient and efficient way to travel between Downtown and the airport.

While writing this, I thought of something else though... given the short distance between many of the stops, will it even be possible to accelerate to the full 79mph much less 100mph?

Exactly.

And there are many at-grade crossings here too. Nothing quite like a train going 125 mph when a car doesn't quite clear the intersection.

Also, just simply the higher construction costs on the class of track needed to accommodate those higher speeds isn't warranted here.

Basically, there's just no need to go that fast for a mile or two before the next station forces a slowdown again.

Actually, there are quite a few arguably "major" intersections that are also not grade separated, to save on cost. Havana and Peoria are prime examples. Also York, Steele, Dahlia, Holly, Monaco, Sable, and Chambers, to name a few.

Really? I can't think of one light rail system in the world that does? I don't even think any NJT trains go that 125 mph, or for that matter any MTA trains (either LIRR or MetroNorth). This is not an "intercity" train where you can achieve speeds that fast.

This isn't light rail. It's electric (multiple unit, EMU) commuter rail.

But you're right, I don't know of any electric trainsets like these that reach 125 mph. German S-Bahn systems usually hover in the 120-140 kph maximum range, which is comparable to this.

Nobody would build a 125mph train that stops every couple of miles. It would be an extreme waste of money.

I wish we could get to the bottom of whether or not these trainsets are going to be lookalike Silverliners just like SEPTA's or the more stylish body styling of the Rotem XG emu which is what is clearly shown in this second "official" rendering:

That brings up a good point...
City & County of Denver, City of Aurora and RTD have entered into an agreement and plan to pay for the full grade-separation of both UP Freight tracks and future East Corridor EMU from Peroria intersection. This will eliminate probably the most busy non-grade-separated intersection, on this project. In fact, isn't this already under construction?

Denver Contribution: $2,500,000
Aurora Contribution: $2,500,000
RTD Contribution: $20,000,000 (including a $13,350,000 Federal Grant)
DRCOG Contribution: $25,000,000 (in form of a DRCOG Grant)

Project total: $50,000,000

Also, while this line is vastly grade-separated from intersections (including all major intersections), there are still many small side streets which will have at-grade crossings.

I think to get FRA clearance for the trains actual maximum speed of 100mph, it would have been much more costly and these three EMU lines are already a $2.185 billion project.

Does Philly run their Silverliner V's at 100mph, or do they go with the 79mph speed limit?

But anyway, these Denver Silverliner V's do have an actual maximum speed of 100mph. That's not bad for FRA-Compliant EMU's. Maybe one day, they will upgrade portions of or all of the routes, to 100mph FRA standards.
Septa's Silverliner V's were just cleared for 110mph by Amtrak , i think they can hit up to 125mph....

Most of Septa's lines are their own and therefore have their own speed limit. The exceptions being a few lines that run on Amtack's track.

But you're right, I don't know of any electric trainsets like these that reach 125 mph. German S-Bahn systems usually hover in the 120-140 kph maximum range, which is comparable to this.
In Britain plenty of commuter trains run at high speeds.

For electric stock, stock is either geared for inner suburban services, that rarely go more than 30 miles from the city. These run max out 75 mph, though it is rare for them to run at these speeds for long periods as they are always accelerating and braking between stations.

Outer Suburban services which run up to a 100 miles from London have top speed of 100 mph. These services have to mix with high speed services and need the speed. These services either run semi express till they get past the inner suburban services and then become local services or run express and only stop at major towns.

Longer distance services that run at 125mph often act as express commuter services for major towns within an hour of London.

Hello, downtown Denver to Denver International Airport is 22.8 miles with 7 stations, averaging a station around every 3 miles. The length of this rail corridor is not quite the 100 miles you're suggesting, which by the way is more appropriate for intercity instead of commuter services.

Plenty of people commute further than a 100 miles to London. But Britain has a well developed rail system and a London is a very big city, so the equations are different. Besides the equations for outer suburban services is that the must run for at least thirty miles and have at least one big stretchof track where they can use a high top speed. A service with a stop of every three miles is not going to need it.

But the higher the speed you run a rail system the further people will consider living from the main city. That has advantages and disadvantages, but if communities further out have sufficient attractions, then people will pay the higher fares.

For the line to Denver Airport, if there is no express option, then a train going 75mph will be plenty. What is more important is how quickly the train accelerates and brakes, as that will determine the actual journey time.

One of the biggest hindrance to the development of high performance commuter services in the States is the weight needed to meet FRA regulations. Your passenger trains will remain slow lardbutts and/or expensive to run until they change.

Wikipedia says the Silverline V's maximum speed is 100mph. Like SEPTA, Denver's RTD EMU lines will be run all on their own track. So I assume, if ever warranted, they could run the trains at higher speeds. Perhaps one day, they will construct express service by-pass tracks at stations, so faster express trains could zip by at faster speeds between the airport and downtown Union Station. Think 2-3 decades from now, that could very possibly be something they'd be looking at doing by then.

Note: The loosing bidder for the Eagle P3 EMU lines, proposed using yet to be designed/built Siemens FRA-compliant EMU's running on even higher voltage and with max speeds in the 125mph range.

But yeah, I think 79mph max speeds is fine for now. during rush hour, traffic flow along this route can be terrible slow, less than 40mph and often far less than that. 79mph will be a significant time savings.

Sorry for not doing the research myself, but when will the segment to DIA be completed? I always feel like crap making my sister drive like 25 miles to pick me up when I fly in. I would love to be able to shoot downtown on the train and reduce her drive to 5 minutes.
