Our combined technologies improve tractive effort allowing you to
PULL MORE WITH LESS.

Thermal Protection
Testing on Jett Hill in Frankfort, Kentucky demonstrated operation in short time rating zones (up to 1,600 amps) for 15 minutes before the Control System automatically reduced amperage to prevent damage to the traction motors. Conventional locomotives need an operator to reduce power after 5 minutes.

Individual Axle Control
On a conventional locomotive, when a wheel slips, all the axles on the truck or entire locomotive reduce power to regain traction. Often, the engineer must use manual throttle modulation to minimize the slippage. Our traction control system reduces and reapplies power to the individual axles, prior to loss of traction, while continuing to send full power to the remaining traction motors.

R. J. Corman Field Study
Jett Hill contains a constant 1% grade over 5 miles with 11 and 14 degree curves. On this stretch of track, CSX rated a 3,000 hp GP40-2 for 1,550 trailing tons. The 2,000 hp RP Series RP20BD used in this study was rated for 1,900 trailing tons. The conclusion: the RP20BD pulled more with less.
