The cruising speed of a train would be 200 km/h. For the Trois-Rivières-Montreal route, which is quite frequent, it would mean that it could be done in half an hour or 40 minutes. What distance does the train have to travel before it reaches its full cruising speed and before it has to slow down for the next stop? In other words, how many stops can we have in that corridor and still be able to talk about a high-speed train?
