Rail Power Systems


Powering the modern railway

We have supplied the rail industry with batteries for over 20 years. We are the UK’s foremost authority on Cyclon batteries and have worked with Network Rail companies to develop and supply batteries and systems for both rail infrastructure and on-board applications.

Using a modular approach we have Network Rail approval for point end switching, level crossing and general signalling batteries and battery/charger systems.

Using our experience we are able to provide technical assistance to supply up to date, modern solutions to replace historical inefficient battery and power equipment.

DMS technologies is the only UK company approved to supply Enersys Cyclon Battery Packs to the rail market.

Manufactured in the UK and designed specifically for the professional user, the Red Flash™ Portable Power Pack range is suitable for starting most 12V and 24V engines – automotive, marine and rail.

All our Portable Power Packs incorporate safety features to protect both the user and the vehicle. Surge and spike protection circuits reduce the risk of damage to the onboard electronic systems and the On/Off isolator switch means power is available only when you need it. The use of fully insulated cable clamps, welding grade cable and highest quality batteries ensure the unit can be used in the harshest conditions and can start the most stubborn of engines.

The polyethene case is extremely robust and will protect the internal batteries and electronics from damage. The case is also fully resistant to oils and contamination found in workshops.
