The London and North Western Railway War Memorial is a First World War memorial located outside Euston station in London, England. The memorial was designed by Reginald Wynn Owen, architect to the London and North Western Railway (LNWR), and commemorates employees of the LNWR who were killed in the First World War. Some 37,000 LNWR employees left to fight in the war—around a third of the company's workforce—of whom over 3,000 were killed. As well as personnel, much of the company's infrastructure was turned over to the war effort. Of the £12,500 cost of the memorial, £4,000 was contributed by the employees and the company paid the remainder.
