The Polar Bear Express?

"The Polar Bear Express today mostly services the residents of Moosonee and Moose Factory when they travel south from their communities that lack road connections to the rest of Ontario. During the winter, many passengers are from communities further north who travel to Moosonee by winter road before taking the train."

Unless you charter a bush plane, or want to perfect your J stroke on a long canoe trip, the train is the only way to reach Moosonee.

There's no roads connecting it to the rest of Canada:

It's not like you'd hop off the train and find an opera house or high end boutiques.

It's the freakin' Canadian wilderness for God's sake.

Tourist go there for precisely that reason: hunting, fishing, camping and whale watching.

Moosonee is a very tiny place. There isn't much to do there. Since Moosonee is inaccessible by road, the Polar Express mainly serves the residents of Moosonee and Moose Factory when they need to go south, and it also carries cargo from the south up to those towns (everything from cars and trucks, to industrial equipment, to retail goods.)

There is a railroad museum...not much else. The draw for tourism is primarily nature. Tidewater Provincial Park attracts campers, and I think there is a novelty factor in going to a town with no road access.

You won't see any polar bears, but there is plenty of non-Arctic wildlife around if you go hiking and camping.
