Here’s a little choo-choo train.
Actually it’s a diesel locomotive, but it is little.
Note the cute con rods which provide six wheel drive without having to use shafts and bevel gears, things which were alien in the days of steam which had only just ended.
Thing is though, how fast can it go, foot to the floor? (yes, I know it doesn’t have pedals. Never mind.)
(a) 15 mph
(b) 45 mph
(c) 75 mph
By way of a clue, it has about 300 bhp which is quite a lot. It’s more than my car. My car will do more than (c).
