Hi. I'm new to posting here, but have been lurking around for a while.
Anyway, ever since the news came out about Metrolinx and the TTC having a hard time trying to decide how to get the Eglinton line across the Don Valley, it really got me thinking. I would say that the best option for building the eastern section of the line is a Transit City surface alignment, with changes to still make the line truly rapid and reliable. Instead of having the LRV's stop for traffic lights at the major intersections, I was thinking it would be much better for just the stations themselves to be grade separated, but in between them, have the tracks run at street level in their own median right of way, without having to stop at a red traffic light. It's kind of like the 202 Northeast line in Calgary, but in this case, no level crossings, no flashing lights, and no lowering arms would be needed. The LRV's can dip down into a ditch under the intersection where the station is located and have an overpass that the automobiles, cyclists and buses can use, or the intersection can be lowered so the LRT line can use the overpass for grade separation and the automobiles, buses, and cyclists can pass underneath the station. Of course I am no expert transit planner, but with tight budgets nowadays and massive debt problems all around, reducing the cost by running on the surface while having grade separation when needed, I think that is the best choice. Now if only Rob Ford could get that through his thick skull and come to terms with the fact that his paranoia of surface LRT and a fetish for expensive underground rail is not the way to do things, especially when both the province and city are sunk in debt up to their knees.
