The Flying Scotsman was seen making its way through Kings Langley station yesterday evening heading towards Watford Junction.

In a video shared with the Watford Observer, the famous train can be heard sounding its horn before green and red carriages roll by at around 9.55pm.

See the video below taken by Ben (a train spotter).

The train is marking its 100th year and is passing through mainline stations to go on tour across England, Wales and Scotland.

Designed by Sir Nigel Gresley and built for the London North Eastern Railway, the locomotive was named ‘Flying Scotsman’ in 1923 and continued in regular service until 1963 and then later in preservation. 

Today, it is owned by the National Railway Museum in York and is operated and maintained by Riley & Son (E) Ltd.
