Unlike steam locomotives diesels were often provided to railways on demonstration to show off their abilities. This practice continued into recent years often with units painted (and numbered) in the scheme of the road they were demonstrating on.

General Motors Aerotrain, a lightweight streamlined passenger train. An ill-conceived design based upon automotive styling and technology featuring GM highway bus bodies riding on 2-axle air suspension system. Two trainsets of one 1200 HP 12-567C (underpowered) diesel and ten 40-seat coaches with a pair weighing just half that of traditional lightweight coaches capable of handling the same number of passengers. Unfortunately, the hoped for smooth ride was anything but. The two sets demonstrated in 1956-57 on four major US roads for over half a million miles but found no buyer. Finally, sold to the Rock Island for Chicago commuter service! Retired at ten years old. Saint-Hilaire, Quebec 1956.
I believe this color photo is at the older long-gone Stellarton,
Nova Scotia station. Car on the rear may be the Sunnybrae jitney.The MAK
arrived in Saint John, NB off a boat from Cuba on April 23, 1956. George
Parks, working Truro roundhouse at the time, says it arrived at Truro
on June 1, 1956. He says it worked on trains 33 and 37 between Stellarton
and Oxford Jct. from August 15 to August 31, 1956, and also other nearby
branches. It also worked on CPR in Quebec
MaK 800D diesel hydraulic demonstrator unit. Built by
Maschinenbau Kiel of Germany.
It also demonstrated on CPR but no order developed and it was returned to Germany.
MLW demonstrator RSD-17 3899 somewhere in Quebec sometime
