Plarail Vehicles Electric Trains First photo: The three on the right have been tested and confirmed to work with batteries. First photo: The three on the left are connecting cars. The one on the left doesn't move even with batteries. There is deterioration, wear, and missing rubber on the wheels. There are also missing parts on the connectors. Cars without rubber may not be able to climb hills. These were played with by children, so there may be overlooked dirt, chips, etc. Please consider these factors and purchase only if you are satisfied. Thank you for looking.
