The rail wheels will lift the front road wheels just clear of the rails while the rear road wheels maintain contact with the rails to provide the traction needed. The steering column also gets locked in position. The driver only needs to control the brake and accelerator pedals. Here is the hi-rail now heading south along the west shore of the Hudson River. When I worked as a train dispatcher for NJT I hi-railed between Port Jervis, NY and Suffern, NY. It was a unique way to see the railroad.
Unfortunately, due to time constraints, the Q-439 and the hi-rail were the only two trains I was able to photograph this day.
