Ok i did this cause i've been bored (just graduated and i have nothing really to do this week), but i thought it'd be cool if the M-Line expansion could be done like this. It would include recreating it completely, with the creation of a new "Ring Line" (cause it forms a ring around the city;alternatively could be called 'Circle Line' because it forms a rough circle), which would follow the existing M-Line (apart VCC, Renfrew, Commercial, Rupert and Gilmore), but instead of turning around at Waterfront it would continue down Hastings and back to Brentwood. This is just a vision, but it would have been really cool if they could built it this way, would reduce transfers at Broadway/Commercial substancially and provide another route downtown, but this time from the east. It would also provice Hastings with rapid transit.
The way I see it frequencies (at peak hours) would be as follows:
M-Line: Brentwood-UBC 2 minutes
Brentwood-Lougheed 60 Seconds (due to Ring Line Trains)
Lougheed-Coquitlam 2 minutes
Ring Line: Columbia-Waterfront 60 seconds (due to Expo Line Trains)
Waterfront-Brentwood 2 minutes
Brentwood-Lougheed 60 seconds (due to M-Line Trains)
Lougheed-Columbia 2 minutes
Expo: King George-Columbia 2 minutes
Columbia-Waterfront 60 seconds (due to Ring Line Trains)
Frequencies of 45 seconds would prob not be needed into/out of downtown because of the relief the Ring Line would give the existing Expo/M-line. Also it would provide people from Sapperton-Brentwood a one seat ride to DT.
The stations for the Ring Line would be:
Willingdon Heights Park @ Kitchener St. and Gilmore Ave (future station)
Boundary Road @ E Hastings St. and Boundary Road
PNE @ E Hastings St. and Renfrew St.
Pandora Park @ E Hastings St. and Nanaimo St.
Clark Dr. @ E Hastings St. and Clark Dr.
Oppenheimer Park/Main St. @ E Hastings St. and Main St.
maps are a little rough but give the overall idea.
