When operating a Trackmobile that has two (2) weight transfer couplers, you can increase the Tractive Effort up to 60%.

Simply couple to one (1) loaded railcar on the back or front coupler and use it as a ballast car. Then you can couple to a string of loaded railcars on the other coupler of the Trackmobile and charge the air brake system. This technique allows the Trackmobile to "borrow" 49,000lbs on the rear coupler & 49,000lbs from the front coupler, increasing the pushing/pulling power.
