These cars are designed to complement your Holiday Express Set. Each is fully assembled and includes the same accessories found on cars in the set. Plus, each comes with two sections of New Style Track so you can display them by themselves, or expand the basic oval of track in the Holiday Express. These two elves never put down their axe or saw as they work merrily to chop enough wood to keep everyone warm. Nightfall wont slow their efforts either because the nearby lamp post will give them sufficient light to work well into the Christmas night. This edition to the Holiday Express Train is a must-have.
