Following the World War II, many railways began to use automobiles and trucks equipped with flanged wheels to transport workers and equipment. With their standard and flanged wheels (which can be raised or lowered), hy-rail vehicles provide flexibility for the railways. They can be used on public roads or on the railway?s tracks. You can occasionally see modern versions, a pickup truck, utility van or sport utility vehicle (SUV), with flanged wheels, traveling along highways and country roads. When they come to a railway crossing, it can be positioned onto the tracks. With the flanged wheels lowered, it can be driven to the intended destination to pick up or drop off workers and equipment. Bachmann?s Hy-Rail Vehicles feature smooth drive mechanisms, detailed bodies, and metal wheels.
