My son got this train for Christmas. Today we have built it. The construction went quite quickly from equip and my son can have been expected to try its so much desired path hardly. But soon gave way to the joy of a bad mood, because the engine / drive train is far too weak. The cars do not reach the loop, if they come at all by the drive and not get stuck. Batteries were changed because I just thought that they were too weak. But the problem remained! Conclusion: The train goes back! Thank you for long faces and bad mood on Christmas Mattel! Product absolutely not recommended
