VIA Rail trip (Montreal-Quebec City)

Next June, I plan to go to Montreal, to soak up the sights and sounds of the city, and of course, I would like to exlpore the STM and ATM. Afterwards, I would like to take VIA on the corridor to Quebec City. I just wanted to know, what train lines or any other information, I would need to know to travel?

Have a look at my trip report from last January about riding the AMT commuter train to Saint-Jerome and a corridor ride to Quebec City.

You may also want to keep an eye out for sales - every summer VIA cuts their train tickets between Mtl and Qc City in half:
