On 22-23 June 2019
No 1 steamed
along a stretch
of the District Line
as part of a season of celebrations
to mark the 150th anniversary
of the opening of the District Railway in 1868.
Rolling stock used included
former Metropolitan District Railway coach No. 100.
This event was billed as being probably the last time a heritage steam train
would be seen in central London on the Underground
due to the impending installation of a new signalling system on the network.
One locomotive, No. 5 John Hampden,
is preserved as a static display at London Transport Museum
and another, No. 12 Sarah Siddons,
has been used for heritage events, most recently in June 2019
running in conjunction with Metropolitan Railway Locomotive No. 1
on steam excursions to mark the 150th anniversary
of the opening of the District Railway.
