A red signal tells a train to stop but on the extremely rare case where a platform is overrun, nothing can stop the train from moving onto the road. Whether that rare tiny risk is worth the traffic disruption is a reasonable question but in our "don't think just follow the regs" region, that isn't something that was discussed.
That’s a good point. Although with modern train control systems, it should be possible to set speed limit triggers as well so that the emergency brake will be engaged before the red signal if it is travelling too fast.
I’m not actually worried about the traffic impacts at Seagram station, but I do wonder about Northfield, Ottawa, and Block Line. Also I’ll be interested to see how Northfield works: the LRT should only trigger the eastbound crossing protection, not the westbound. During tow testing I think sometimes both were triggered but I think somebody said that was manual.
Agreed with whoever mentioned the media. They absolutely should by now have run one or two short items about the powered testing. Doesn’t have to take long, just a brief clip and a couple of sentences about what is happening.
