That's an interesting point about the Confederation line. However, by comparison the line 5 light situation would then mean there is that longer low-floor dwell time, plus traffic light delay. Again, I hope that more aggressive TSP is implemented.I mean, dwell times will be long simply by nature of it being low floor. Low floor means more erratic door spacing, as well as less doors period. This means more people bunching trying to exit and enter the train, and thus the train dwells for much longer. Compare dwell times in Ottawa vs Toronto for a good comparison.
