Finally, a scale passenger train that will fit ANY layout! At just 3.5 inches each, an entire 5 car train is shorter than one of our 21" passenger cars. Based on our logging disconnect trucks and a whole lot of whimsy, these little minis are packed with detail inside and out. Perfect behind smaller scale locomotives or traditional O Gauge product, these trains will look great under the tree or mixed in amongst your other trains on a layout. Good things do come in small packages - including complete interior details, die-cast sprung trucks and the ability to convert to scale couplers.
