THOMAS & FRIENDS™ MINING WAGON with LOAD - BLUE - Large "G" Scale. Wagons (commonly referred to as trucks) form a large group of railway goods wagons designed primarily for the transportation of bulk goods and freight. Due to their ubiquitous nature on the railway, they have been employed for transporting a variety of other materials, such as wood, sand, china clay, bricks and even debris after large storms. Bachmann carefully reproduces your favorite Thomas & Friends™ characters in HO scale. All rolling stock features realistic character faces (where applicable), highly detailed, realistic plastic body shells, all-metal wheels, and international-style hook-and-loop couplers
