The Caribou, colloquially referred to as The Newfie Bullet, was a passenger train operated by Canadian National Railways (CNR) on the island of Newfoundland.

CNR renamed this train in 1950 to the Caribou and it maintained approximately the same 23-hour schedule from St. John's (also the eastern terminus of the railway on Newfoundland), to the system's western terminus at the ferry terminal in Port aux Basques, where connecting ferry services to the North American railway network at North Sydney, Nova Scotia, were made.

CN withdrew the dedicated passenger trains in July 1969 and instituted a bus service, marketed under the name "Road Cruiser.

"[2] CN maintained limited "mixed" passenger and freight train service to certain isolated communities on the island until the complete abandonment of its narrow gauge system in the fall of 1988.

The CN Roadcruiser Bus service operated until March 29, 1996, when it was sold to DRL Coachlines of Triton, Newfoundland.
