Our son (3) got this package for my birthday. He was thrilled. It is included a certain number of tracks. Variability thus adheres naturally limited. The extension with the appropriate bridge is highly recommended. If you think with turnout at an extension, I recommend the same 4 pieces (2 luggage.). When you buy points to additional tracks are required. The train can be "refueled" with batteries. The battery compartment is secured by a small screw, so the little ones do not come so easily to it. The drive will only work if the locomotive is on the tracks or the floor. If the locomotive detained in the amount or, the drive switches off - for safety. Even after 2 minutes continuously before the drive switches off. Start and stop are accompanied with appropriate sounds (diesel engine and "brake squeal") - but in absolute tolerable volume. Move the locomotive toots sometimes the horn. In addition to the locomotive and two cars also plenty of railway equipment are: barrier, crane dock leveler, gas station (the locomotive "chuckles" if it is refueled), truck, recycling center, 3 figures. And of course everything can be completely rebuilt. For example, instead of shunting a locomotive with an open cab and a wagon with a large crane ...
It is a pity only that the locomotive runs in only one direction (earlier versions were forwards and backwards) and that the start-up behavior is a bit temperamental - slower is better, especially for children under 4. But the on / off button on top of the locomotive can be well met, because it is quite large.
For the price an absolute bargain. Strong buy recommendation. We have LEGO DUPLO for a year now and so far there were no failures.
