What small children not yet Remember: the quality pretty bad, now much worse than anyone has known "in our childhood" of Brio. Made of real wood are only the tracks, everything else is plastic. If you build on a carpet, the connectors are a bit uneven and the coatings remain hanging it. The males have to hang wide arms, they remain on the bridge. The connectors have so much tolerance that the whole train wobbles and fall over the supports to the highly specified bodies permanently or moved. It is battery operated and only one locomotive, the other not. The electric locomotive has not a lot of grip on the drive wheels, a slightly longer train can no longer pull up the slope.
The Brio railway system is indeed now copied by many manufacturers - no, "compatible designed" - so I'm still looking for a quality alternative that suits Brio.
