Thames Valley Signalling Centre is on a busy mainline rail network that thousands of commuters and travellers rely on every day. It all hinges on having continuous power, so when Network Rail needed to take the centre off-grid to upgrade a breaker in their switchgear, they needed interim power - and they needed it fast.

Network Rail had a back-up generator but as it was linked to the switchgear that was being upgraded, it couldn’t be used. There wasn’t much room onsite either, so anything installed needed to be as space-efficient as possible.
