"I held off for a long time buying this, as high speed trains are really children's toys. I mean, only one motor unit, one carriage and one steering unit is not really a train. But with two, it's a whole different ball game. There are enough bricks to make two carriages from the three units, so you have a five unit train. Now it looks cool!
As one power unit is enough to move the train, you got a spare bottom plate and power unit for your own project. My son and I made one unit a restaurant unit, which looks really cozy. Other parts have been adjusted to fit more seats."
