Unknown diesel engine.
Nope, this ain't a diesel at all 😁
What's happened here is that someone's taken the front car of the Plarail 485 Series EMU (the 'Tomy Express' to all us Tomica World collectors) and modded it to fit onto a Thomas loco chassis, for reasons that only they know why lol
I can assume this was their vague attempt at cloning the special edition Plarail Jurassic World train since it has dinosaur wagons attached, but dear lord is this a bizzare train, an EMU driving car pretending to be a diesel loco that has steam wheels with connecting rods (why?) and 2 shoddy looking dinosaur wagons, all in a vaguely Thomas-themed package 😜
'Rail Master', yeah right lmao
Been building Plarail worlds since 2001; Building when I can in 2023
