The term smokeless locomotive actually refers to what is more commonly known as a "Fireless" locomotive. These locomotives were used where the fire of a conventional locomotive might prove hazardous - munitions plants, creosote plants, etc., or by facilities wanting to maintain a smokeless environment such as large hospitals, or packing plants. The "fireless" boiler was actually a reservoir that was filled with steam from the steam plant or air compressors at the facility. The engine would perform its chores until it ran low on steam, at which time it would return to be refilled.

If I recall correctly a friend of mine has a Porter builders list. When he returns from his current travels I may, just for giggles, see if I can find the construction number and build dates of the two CVR locomotives.
Cheers,
