<p>London Underground C Stock train at the Metropolitan Railway station which nowadays is only used by Circle &amp; District line trains.
</p><p>The train doors had failed and a member of station staff is seen using the emergency door open control located on the side of the train car - this only releases one of the four pairs of doors but is still far better than being trapped inside!
</p>
As there is no-one inside it is likely that the member of staff was actually closing the doors when I took this photograph.
