TMR - Reversing Transmission for Hi-Rail Applications

TMR - Reversing Transmission for Hi-Rail Applications

To show the diversity of Waterous products, we developed a transmission for a vehicle which can operate both on rail tracks and a conventional road. The Hi-Rail, from highway and rail equipped with a Waterous TMR Transmission allows the vehicle to travel forward or backwards without having to change the vehicle’s transmission setting saving wear and tear on the vehicle transmission.
