Abstract
A road and rail vehicle has a truck tractor vehicle frame such that it is street legal, but also provides sufficient power to move freight cars on low density rail lines or at other desired locations. The vehicle has a transfer case to provide front wheel drive by road wheels when the vehicle is in a road or highway mode and to provide rear wheel drive by rail wheels when in a rail mode. The vehicle has a front guide rail wheel unit which moves front rail wheels between an upper road position and a lower rail position. A rear or back axle has right and left back road wheels thereon and is movable between an upper rail position and a lower road position.
