This is a set of 6 Plarail Advance train cars. There are 2 lead cars, 2 motorized cars, and I believe 2 intermediate cars, but please check the photos for confirmation. Both motorized cars have been tested and are working. They move forward and backward. They can also be connected as shown in the photos. Both will be shipped with batteries installed (one battery is new) via Yu-Packet Post. These are toys that children have played with, so please expect some minor scratches and dirt. Please refrain from purchasing if you are concerned or overly sensitive. Thank you.
