Rail Power Systems

For over 20 years, the world’s largest locomotive  and rail car manufacturers have relied on Espey to deliver rugged, reliable power management and conditioning components required  for the harsh environment and long MTBF’s common in the freight and light rail markets.

In an industry that is becoming increasingly global and competitive, locomotive “up-time” has become a critical determinant in the selection of locomotive and car suppliers.  Operators expect high MTBF’s, long life and maintenance-free operation in the difficult vibration and temperature environments common to rail. Espey delivers that capability.

Whether in power management and switching operations of diesel –electric locomotives, or the critical electro-hydraulic braking systems electronics modules, Espey’s products have logged tens of millions of miles of maintenance-free operation.

Espey also maintains  a robust logistics and repair capability to service long-lived components; when those Espey components have exceeded their designed life, they can be returned for refurbishment and re-issue for many more years of service life, further stretching operational value.
