More Info
HEP or Head End Power Units are also referred to as Wayside Power Cabinets or rail yard power. ESL’s units provide power to the HEP systems on a passenger car when the locomotive engines have been shut down and/or disconnected. Hooking a passenger train up to HEP units eliminates the idling of a locomotive’s diesel engine which decreases costs and reduces the number of toxins released into the environment. Below is ESL’s product selection guide for HEP Units.
