Pretty freight train

Package delivered as usual; quickly without any problems, thank you to your team, and the deliverer.
Good train, the locomotive is correct (except for the bad connection in the battery case, but hey I already have two trains ICN 60051) for testing so I reversed with the train "white" and there it works I ordered another box on Brick Owl. it works the first time.
Otherwise the cow wagon is for me no, but my son is the fun, the train for him anyway, but must be recognized that all three cars are lighter can. Think of buying batteries and batteries advance especially if you have other cars to hang out more, this course adds weight.
It lacks more than the station now.
For rails against buying more because for the price, Lego could add some rail rights in the box.
