Thank you for the info, I will call them unconventional steam engines from now on.
Also, here are some WWII railcars.

"Locomotive" is defined as a self-propelled verhicle able to move independently from place to place. So the fireless engines are still considered "locomotives."
It might be better to call them "unconventional" steam locomotives, as opposed to conventional steam locomotives that use a firebox and boiler to create their own steam pressure.
