The Llantisilly & Montgomery Railway is a small railway dating back to the last days of the 19th Century. Originally serving a few villages like Llaniog in the top left hand corner of Wales, it still runs as a tourist line nowadays. But it is most famous as the railway of the star of screen and Welsh choir Ivor the Engine.

When it was a working railway it conveyed mail down to the main line in accordance with the 1891 Railway Letter Agreement. The letter stamps followed the standard green design, but the Newspaper stamps were also used. 2d and 3d examples each can be found. Since it has been run by volunteers souvenir stamps have periodically issued. Most sought after are Solstice Express stamps used on cover and postmarked on 20th or 21st Dec.

And before you ask, Ivor still operates there, always at his own pace, but Jones the Steam retired a few years ago.
