What are life­guards?

Rail (UK) - - Feature Rail Rovers -

Life­guards are me­tal pro­tru­sions that sit in front of the lead­ing wheels on main line rolling stock, like a mini ob­sta­cle de­flec­tor.

As the Rail Ac­ci­dent In­ves­ti­ga­tion Branch’s di­gest into the in­ci­dent at Cradle­hall (near In­ver­ness) on Feb­ru­ary 25 2018 shows, they can help prevent de­rail­ments - in this case by push­ing rail left on the track out of the way. Of course, had the an­gle of im­pact - or the ap­proach speed - been dif­fer­ent, the train in­volved may well have de­railed.

Sim­i­larly, at Frox­field ( Wilt­shire) on Feb­ru­ary 22 2015, a lorry knocked a 13-tonne bridge para­pet sec­tion onto the line, where it was struck by a High Speed Train. The lat­ter’s life­guards ap­pear to have been in­stru­men­tal in pre­vent­ing a de­rail­ment here, too.
