Clearly showing the difference between a train of Tube Stock (left) and a train of Surface Stock (right), a train of A Stock led by 5100
overtakes a train of 1996 Tube Stock at Kilburn. The A Stock was on a Metropolitan Line service to Aldgate, and the 1996 Stock was
calling at Kilburn with a southbound Jubilee Line service. One of my pet hates is how many people call everything on the Underground
'tube' (including TfL themselves).
