You guys have completely missed my point.
Considering the horrid ridership, UPX is a scandalous waste of money and heads should be rolling at QP but it was a political line to begin with and the decision to build it was solely due to the Pan Am Games and had nothing to do with proper transit planning.
UPX can, however, prove to be useful as a testing ground for RER. RER is a great idea but there is surprisingly little solid information to back it up. It's relying on the "build it and they will come" transit planning and certainly sometimes it works and other not but it's rare to have an actual system up and running that can be used as a gauge for success and demand. Toronto is in that position with the UPX so they should take advantage of it.
UPX is RER...............all day, 15 minutes each way service using single level EMU/DMU designed trains. ML should be using the UPX as a information gathering tool for a RER roll out............you wouldn't buy a car without driving it first, so why build a RER without gauging public opinion about it?
These new commuters from Weston using the service new riders or just riders switching from GO?.......find out. How are people getting to the stations walking, bus........find out. Would the riders rather have less glamour on their ride with cheaper prices?..............ask them. Has anyone thought of doing a 4 week trial and bringing in fair integration just for this one line where the base UPX price is the same but if you got to the station by TTC then the price will be deducted 100% from the YP fare? ............do it and study the resulting changes {if any} in ridership on the UPX, GO ridership along UPX stations, and changes in TTC bus/subway ridership that serves those stations.
Then try another 4 week trial of a flat etra fee on top of your TTC ticket/pass of an extra $0.50 from both Weston and Bloor to Union and a $6 Pearson fare.........and again study all the stats including ridership along the Spadina subway line. Use it to understand what a corresponding service on the other side of Union to Scar would have on traffic on Danforth and the Y&B station.
Eventually allow another 4 week study on completely free fares with a TTC ticket or pass treating just like any other TTC service and again studying the results.
Find out what all the above trials have on revenues as ML may find that the cheaper the fares go, the more money they have coming in. Use the info to extrapolate how a RER in Toronto would effect TTC traffic point, over crowding, and revenues. ML could actually find out what ALL Torontonians think of the service and not just the ones who can afford to take it. Look at the changes in ridership but also who those new or switched riders are in terms of age, work and destination which will help determine how many Pearson employees would take the service if they could afford it.
The UPX is a wealth of information so take advantage of that opportunity and use it as such.
