The C Stock is next on the TfL hit list as the final days of the A Stock draw to a close... From what I can gather, one unit - 5595 - has already been withdrawn and stripped, although it had been out of traffic for some considerable time anyway. Although no S7 stock is expected to enter passenger service until after the Olympics, the first unit 21301/2 has either already been delivered or is on the point of being delivered - it was seen at Leicester being moved from Derby to the test track the long way round three weeks ago. There is one oddity amongst the C Stock fleet - unit 5555 apparantly can only be formed in the middle of a rake as it has some long term problem that causes it to fail if it is being directly driven and they have never managed to pin down why; little point spending the money now to sort it out anyway. One question: Does anyone know how often the C Stock rakes are split and reformed? They do seem to stay together for a considerable time, but equally they do seem to have a constant low level of reforming going on.
