A report on an ambitious attempt to build an LMS Patriot class locomotive, none of which were saved for posterity in the 1960s. The Unknown Warrior will serve as a permanent memorial to all those who fought and died in the First World War and all subsequent conflicts. The enthusiasts behind the project have already built part of the engine at the Llangollen Railway and are hoping that when its finished it will wow the crowds just as much as Tornado has done. They've been endorsed by the Royal British Legion and want The Unknown Warrior to be a National Memorial Engine similar to one built after the First World War.
