Today marked the final service runs of D78 Stock on the London Underground. The Metro-Cammell built trains have been in service since 1980 so have had a good run which has now come to an end barring railtours and departmental use (a new Rail Adhesion Train has been made out of withdrawn D78 Stock). Many may also live on as "new" diesel powered trains outside of London though that project is still in its development stage.
The last D78 Stock train i travelled on was on January 23 of this year when i got off at Temple and took the photo below. I didn't know at the time it would be the last one i would travel on but obviously i knew their days were numbered so i took the photo just in case. Of course i am glad i did!
