Description
The cranking group is MS500, LMS, UB and LMUD. What counts here is a short burst of hundreds of amperes into a cold engine, with the locomotive alternator recharging the battery between starts. MS500 is AGM and needs no watering, while LMS, UB and LMUD are vented and serviced in the depot by electrolyte level. ELM and DDr are meant for wayside equipment. They spend years in relay cases at crossings and keep signals alive when external power drops. DDr is AGM and suits remote cases with rare visits, ELM is vented and easier to check with a hydrometer.
How to choose
First define the task, diesel starting or signaling, then the technology by how often the battery can be serviced, and the capacity within 80–725 Ah. The 2–32 V voltage is built from cells and monoblocks to suit the onboard system or the wayside case. For European DIN-format rolling stock the Hawker ZeMaRail, PerfectRail and EvoRail range fits better, and for wayside sites with frost GAZ nickel-cadmium batteries cover −50…+70 °C.

FAQ
Which PowerSafe models are meant for locomotive starting?
Diesel starting is handled by MS500, LMS, UB and LMUD, with the range spanning 80–725 Ah at the 8-hour rate.
Which batteries suit grade crossing signals?
ELM and DDr are intended for signaling and communications. DDr is AGM, ELM is vented.
Does the MS500 battery need maintenance?
MS500 is AGM and needs no watering. The vented LMUD, LMS and UB require electrolyte level checks.
What voltages do PowerSafe railroad batteries have?
The range has cells and blocks of 2–32 V, assembled to match the locomotive onboard system or the wayside case supply.
