Maintenance Of Way (MOW) vehicles are crucial to maintain the operation of any rail line. From light to heavy duty work, these trucks are equipped for service. This model can be built in one of two different configurations - locked down traveling mode or opened up with outriggers in place to stabilize any heavy lifting. Also included is one set of The Standard Service Truck or Machine Shop Tools - welder, torch, tool boxes, cans and drums. This model comes with standard steel wheels. If you want to customize these work trucks further, we offer the Medium Duty Alloy Wheels and the Medium Duty Cast Wheels sold separately. Watch Steve DeHart's 5 minute video of his excellent build of this MOW. --- https://www.youtube.com/watch?v=45Vyq4P9dhY
