Huh? I'm not sure if you're serious but I can give it a try.
Short answer : The tracks to Lévis have been removed decades ago and it's now a bike path.
Cynical answer: There are still tracks close enough to the city that a connection and new station could be built. However Via Rail is required to be profitable so it wouldn't happen. It's North America, just use a car (electric)!
Car-less person answer: You kind of can. Take a train to Québec City and use the ferry to Lévis.
But to me the bigger rhetorical question is, why the hell doesn't the Québec region have any kind of commuter trains.
