If the gauge was the same the new city LRTs could run on the Eglinton line but the new TC LRTs couldn't run on the city lines. There is no reason greater ability to handle curves, more powered wheels, etc would prevent the new city LRTs from running on the Eglinton line. The new city LRTs are built to convert to pantograph as well.
The Transit City lines will operate at a higher voltage - 750v dc rather than 600v dc. As well, the cars are wider by a foot - 9 and a half feet versus 8 and a half feet. And of course, there is the whole issue of double-ended versus single-ended, and the doors on both sides. And finally, the Transit City cars will have proper couplers and MU capability, whereas the cars for the legacy system will have couplers designed for emergency use only.
So, as we see above, the track gauge issue is almost the least of their concerns in terms of running the equipment together.
There is really no significant cost for getting TTC gauge vehicles. They are probably making more TTC gauge vehicles in Thunder Bay than standard gauge. Even though the subway cars are TTC gauge it wasn't an obstacle to sell them to Nigeria. I think the gauge cost benefits are seriously overstated from the costs of not being able to build a network which includes the network that already exists. For example a Kingston Road LRT... what gauge? A Dundas West LRT north of Dundas West station... what gauge? An extension of the Lakeshore West LRT into Mississauga... what gauge?
The cost comes from the engineering, not construction. The per-unit cost per car is probably in the same ballpark for each ($4.1mil, as per the Transit City purchase) but the total purchase price for the 204 legacy fleet cars - including all testing, prototyping and yet, engineering - brings the cost up to over $5.8mil per car.
And frankly, you can't compare the subway cars to streetcars anyways. A subway car rides on top of the trucks, much like a CLRV or PCC, and thus it is much easier to change gauges. On modern low-floor cars such as the new LRVs, the car surrounds the truck, which means that they have to be much more careful about equipment placement.
But you do raise a good point in terms of the system. I guess what will have to happen for the various lines is to figure out and compare what that future brings for them: What kind of capacity will be needed at the time of construction versus 20 years in the future? Where will they connect with other routes? Is through-routing with other routes beneficial, either at the time of construction or 20 years in the future?
Of course I am looking at it in the context of what is currently planned... because when Eglinton is completely underground all the parts of TC that were logical are no longer logical.
Agreed to a degree. But we're also stuck with the current EA, unless Mr. Ford wants to go back and start that again as well.
And, of course, changing the mode will bring back the question about what to do with the SRT, as well as planning for any extensions to it or connections with it.
