Very nice locomotive metal. It is much heavier than the Brio locos are weight helps adhere well to the rails. It has 4 wheel drive which allows it to always move at constant speed, even downhill.
It is compatible brilliantly, but tends to hang on the corners (the middle of the wheels are raised to pass). It has an LED at the front.
The big problem with this loco is its switch. It's not easy to put it on / off, even for an adult.
