Perhaps some of these finer details will be changed over time. Now that the vote has been taken the route may be fine-tuned.
With all the publicity over LRT, buses, cycling paths etc. it has been forgotten that Waterloo already has an LRT in place! I was riding my bike to work up at the U of Waterloo Research park the other day when I came across Waterloo's LRT doing its business with little fanfare or public attention. I am including this picture I took of it, and you can see there is a great deal of room for expansion of the service into more trains. The upside is unlimited!
