HERITAGE trips on a classic London Underground train were cancelled today by London Transport Museum (9) after the train was vandalised.

The restored 1938 stock was due to travel on the Piccadilly line between Acton Town and Oakwood stations.

Six £22-a-head journeys were planned from around 10am to 8pm. Ticket holders were due to hear from an LTM curator about how they care for the 86-year-old stock.

There was also to be a talk about the architect Charles Holden, whose design influence can be seen across the Underground network. 

Disappointed enthusiasts responded in outrage, with one branding the vandals "feral filth" on social media.

The four-carriage train is based at the LT Museum Depot at Acton Town, but it's not clear where it was vandalised or how.
