Steam engines! (stationary steam engines only in museums, so no longer in the spoken language). I haven't checked, but in the days of steam, the word locomotive may well have been in use in North America. I will have to look in some of my old magazines. Don't know why "locomotive" is not in the general patois. The freight trains that run through town are called "diesels."
There no longer is any real use of passenger trains in western Canada. There are preserved railroad steam engines, some still running short excursions, so the public is familiar with them.
Farmer-mechanics here take great pride in their restored steam traction engines (just "tractors" to the general public, whether steam or gasoline).
