Pedal powered rail vehicles date back to at least the 1850’s, when maintenance workers used hand-cars and ‘rail bikes’ to travel along the tracks. They were used to transport crew and materials for track inspection and repairs. Today, there are a variety of designs in use around the world: the ‘Draisine’ and ‘Velorail’ of Europe; ‘rail bikes’ with aluminum frames and rubber wheels; and modified road bikes with an outrigger wheel.
