The G Scale Bachmann Big Haulers Engine Tender and Passenger Wagon with Track is a model steam locomotive set designed for collectors and enthusiasts. This set includes a steam locomotive, tender, and passenger wagon, all in a G gauge size. The two-rail system and DC power type ensure smooth operation on a model railway track. Bachmann is a trusted brand known for producing high-quality model railways, making this set a great addition to any collection. I don’t think this engine has been run have checked it out it runs well the passenger carriage doesn’t look like it’s been out the box. The track has a diameter of about 53. Bought years ago to setup in garden but never got around to it.
