Yes, the 30 minute improvement is only for the 135 miles of the soon to be ex-Norfolk Southern tracks from Kalamazoo to Dearborn. The 30 minutes is stated in the Michigan $196.5 application submitted last spring for track & signal upgrades from the re-allocation round of the Florida HSR funds. The upgrades for that segment for 110 mph speeds are expected to be implemented in stages over 3 construction seasons, to be completed by late 2014.
The 97+ mile Amtrak owned segment is reportedly close to receiving approval for 110 mph operations this fall. I believe some parts of the Amtrak segment are currently approved for 90 or 95 mph, so the increase to 110 mph will likely be a modest time improvement for that section. The crossover project in West Detroit is listed in another Michigan DOT application as a 5 to 10 minute trip time reduction. The Englewood Flyover (construction work was supposed to have started by late summer 2011) and the Indiana Gateway Corridor project will also reduce trip times. The $71 million IN Gateway project is described mainly in terms of reducing congestion, improving on time performance, and increasing capacity than reducing total trip times, but fixing known choke points can result in removing padding from the schedule with faster scheduled trip times. The Englewood Flyover and IN Gateway project will also help the Capitol Limited and Lake Shore Limited long distance trains.
The stated goal for the upgrades that have been funded in IL, IN, MI is for a Chicago-Detroit trip time of around or under 4:30. That is an over a hour faster than the current schedule. Pretty good return for the funds granted. The ultimate goal for the corridor - in terms of 110 mph max speed diesel locomotive powered trains - is a four hour Chicago to Detroit travel time with, IIRC, 6 to 8 daily trains. When the new bi-level cars are delivered, Amtrak and Michigan may increase from 3 round-trip trains, but I don't recall seeing specifics on this.
For anyone who is interested in reading the HSIPR applications, Michigan has all of theirs available at
