Later this month the last remaining D stock train running on the London Underground will make its final trips as a public train service.

The District line D Stock train was introduced in 1980, but over the past few years, the entire sub-surface fleet of trains has been replaced by the walk-through, air cooled S Stock trains.

The last D Stock train is scheduled for all day public service on Friday 21st April, after which all the trains on the Circle, District, Hammersmith & City and Metropolitan lines will be replaced by a single fleet.

To celebrate nearly 40 years of service, there will be a special farewell tour on Sunday 7th May, a last chance to see these trains on the London Underground.

On the day, the special six-car D Stock train will operate as Train 755 and will travel to all parts of the District line – except the High Street Kensington to Edgware Road section. It will also visit Northfields on the Piccadilly line.

Customers will depart from High Street Kensington at 09:55, with an opportunity to alight at Northfields at 12:56 for an hour’s break, where there will be a pop up shop in the ticket office. The trip will finish at Ealing Broadway at 17:50.

Tickets go on sale on Tuesday 18th April 2017 at 10am.

Ticket prices are £50 per person and £25 for children aged 11-16 (children 11-14 must be accompanied by an adult, who will require a ticket to travel). Children under 11 are not permitted to travel on this trip.

A maximum of two tickets can be purchased per person.

Keep an eye on the Transport Museum website for details closer to the date.
