Hello My son received the lego train for Christmas. He is six years old and the construction of a lot to him pretty easily. But our first small'd had when we were trying to stop the train unfortunately my son had the transmission frequency of the remote control is adjusted so we thought until the train would not go after 5 minutes troubleshooting but we had both frequencies set to one and already the train was going. It is pretty fast and works very well. But unfortunately, far too few tracks here that means that you can build a circle covered already half full with about good followers. The locomotive runs so fast that they derailed several times at this small circle.
So that means buy more rail which are not cheap. Otherwise, the Lego City train is a very nice toy but you must also think I can weitermempfehlen to the follow-up costs this product anyway without hesitation.
