Class 57s modified for faster rescue
Network Rail is speeding up its ability to rescue failed electric multiple units with specially adapted Class 57s.
The rescue trains’ brake interface units have been modified to allow drivers to operate their own brakes and those of the failed train together. The train can also operate the safety interlocks, allowing broken-down units to be removed at normal line speed. This means rescues can be completed in 15 minutes.
The Class 57s will also routinely move EMUs between works for servicing.
Mick Stewart, senior fleet engineer, National Delivery Service, said: “We can now quickly move units that are stranded – for example, when the third rail network is disabled, if there’s snow and ice, or where there’s been a mechanical failure.
“The 57s are also powerful enough to haul a 12-car EMU – another EMU wouldn’t be able to do that.
“Before, failed units had to be rescued using whatever train was available, powerful enough, and that could be coupled to the unit.
“Route controls would have to source the rescue vehicle, find competent fitters and get them to the depot to collect the emergency adaptor coupler before the recovery train could go out – all of which took valuable time.”
