In a previous post on page 2 i neglected to include a link to my vision of the RT ROW between Sportsworld and Preston. Take a gander
Concerning a Cambridge GO line; there is more priority to extend the current Georgetown rail line into Kitchener VIA Guelph. Also, GO has already made a priority to double track the system from Union to Georgetown which is essential to improve system efficiency. It's only a matter of time before the system is expanded into Kitchener (with double track I hope). However nice it would be to have the GO train system to run into Cambridge it is currently not a priority, however I feel that the region could make this priority. GO transit currently has a lot of strides it must make in improving system speed and efficiency on its current network before it can effectively expand.
As for location of the station, I like the idea of a dual station approach, one central Galt station and another Park and Ride on Franklin. I have no real opinion over the exact location of a Galt station, but it would need to be integrated directly into Rapid transit whether it be at Samuelson or the Delta (I'd prefer the Delta but eh..)
Aside, Imagine something like this at the delta (in 10 or 20 years); a traffic controlled roundabout with a below surface RT line and station with pedestrian access tunnels.
(i'm sure many of you have seen this picture before, taken from Roundabout on Wikipedia)
The main reason I prefer the Coronation route over the Hespler route is because it is the most direct route between Kitchener and Galt, also it serves established town centres.
Hespler Road as it exists today is a very unfriendly place for pedestrians, with large parking lots, limited road crossings for pedestrians, and overall auto supremacy. The Hespler corridor is not dense enough to support a rapid transit line with limited stops and would be difficult to create such density in the corridor. With time, this may change, but currently it is a typical, suburban, sprawling strip mall.
Preston, however provides more promise for creating a destination for pedestrians, already posessing history and retaining its town identity.
In the future, my dream would be for the RT line to extended from the Galt Core up along Hespler Road and into the town of Hespler proper. This would likely be at least 10 years off from the completion of the current RT system. But, along with the RT system, there is also going to be improvements to bus systems to travel along major corridors with more efficient crosstown service, there is no doubt that the demand will be there.
