Are you finding WHEELED EXCAVATOR RAIL GEAR . We are your ideal shop. The advantage of friction drive is that the tires straddle the rail so the machine can get on/off the rail without crossing. With simple guide wheels, the inner dual tires barely drive on the rail and you need a rail crossing to safely get on/off the rail.
