There do seem to be some signaling glitches with the ATP - we should be able to hit 70 on the Waterloo Spur. Places with an up arrow or down arrow seem to be the places where the ATP kicks in. I was talking to a signaling engineer (who did not work on this project) and they think that the ATP speed blocks are incorrectly placed (too far behind stations) so there is improper control.
We have a weird ATP system. If you look at Ottawa's, there are glorified little RFID tags (balises) bolted between the rails at regular intervals to let the trains know exactly where they are. I've heard that our system instead relies on the AC track signalling in the same blocks that are used for the crossing gates and other signals. It's accuracy is finicky, and I suspect we were over-promised while the equipment provider under-delivered. If they can't simply tune (or software upgrade) their way out of it, then they should add more blocks until they can get it to work correctly, on the provider's dime.
Of course that's easy enough for me to say, but I suspect the contracts around it were weasley enough (how well did the region really understand the technical implications of what they were signing?) that we'd have to pay substantially for such rework. There'd probably also be significant downtime. Ultimately it needs doing though, especially if the headways are shortened in the future to deal with increased demand.
SideNote: we have updated planning info for the Cambridge-Guelph Rail concept:
Cambridge to Union Passenger Rail Connection Initial Business Case and Concept Design
Project Overview The Region is developing an Initial Business Case to explore passenger rail service between Cambridge and Guelph, connecting to Union Station via the Kitchener GO Line. Providing an efficient, well designed transit service for Cambridge residents towww.engagewr.ca
Thanks!
Edited: Grammar, readability, and added the word/link for balises.
