Military personnel and veterans attending services of remembrance next month can travel to and from the events by train for free.
The offer, provided by the Rail Delivery Group (RDG), applies to remembrance services across Britain on November 12.
Veterans and serving personnel attending the Remembrance Sunday ceremony at the Cenotaph can travel to any London terminal for free on Saturday 11 November or on the day – and be able to return home for free afterwards.
RDG Chief Executive Jacqueline Starr said: "During this period of reflection and remembrance, the rail industry is proud to help the service personnel of today... travel to ceremonies up and down Britain".
Transport Secretary Mark Harper added: "Remembrance Sunday is an important day of reflection... It's right that our veterans and serving military personnel will have free rail travel".
Free rail travel will also apply to Royal British Legion volunteers collecting for Poppy Day in London on November 2 and Manchester on November 9.
