I would never have guessed that combining a first class compartment coach with a dynamometer was a real idea. But I trust Carl Greatrix (bricktrix) to have done his homework. Although I’m not blogging it for its unusualness but for its lovely looks. There a few touches that purists may not like but it’s a gorgeous old wagon however you look at it.
PS. And no, speedometers are not the same as dynamometers. But the concept is much the same.
