The engine is very reminiscent of the 160hp Daimler Mercedes range which started out as a 150hp design circa 1914, and 215hp by the end of the war. Its not easy to see on my old mobile phone scrern, the early ones had 3 pairs of cast cylinders, later these were all individual for economies of repair (1916). Clearly these german / Austro-Hungarian fliers and mechanics are a risk loving bunch !

Yes, it's a Mercedes F-1466D-3A engine.

These are German pilots from Fliegerabteilung 302 or 304.

Alarmingly there seems to be no braking mechanism on board. Is it a suicide train?

There is a brake, but how to use it on the go is a mystery

Presumably, the track gauge is 1050mm. Perhaps a car built in the UK

Hello. Please tell me the type of car in the photo.
