Vintage Tube trains journey into London's Metro-land

An opportunity to ride on vintage Tube trains will be on offer on Saturday and Sunday.

The London Transport Museum (LTM) said fans of "1930s train chic" who buy tickets for the event will travel on a series of special services on the Metropolitan line.

The historic Sarah Siddons locomotive that first went into service in the 1920s will be part of the journey alongside four 1950s ex-British Rail coaches.

Passengers can also take a special trip on the museum's restored 1938 burgundy art deco-style train.

Henry Flynn, curator at LTM, said the Sarah Siddons electric locomotive no. 12 is a rare survivor of the 20 in the original fleet.

He told BBC London: "There are now only two survivors - one is in our museum in Covent Garden and the other is the Sarah Siddons, the only one that is still working, so it's very exciting."

As part of a publicity campaign in March 1927 designed to promote Metro-land in north-west London and the development of suburbia, the locomotives were individually named after real and fictional personalities associated with the Metropolitan Railway catchment area.

Sarah Siddons was a Welsh actress who rose to fame in the 1770s. She died in 1831 and was buried at Paddington Green cemetery, not far from the Metropolitan Railway's original terminus.

Some return journeys will be via the North Curve, a rarely used and section of the track connecting the Rickmansworth branch and the Watford branch.

This part of the line is used mostly early morning or late at night for moving empty trains and occasional engineering diversions, LTM said.
