More trouble Thursday, as I was leaving BAN WB the train behind me was stopped by an “obstruction on the tracks”, something we normally hear when a branch falls off a tree during a storm or bored children on school holidays find an amusing use for shopping trolleys, certainly not something you expect at LIS at the end of the morning peak.

In 2003 the whole Central Line was closed down for months after a train was derailed at Chancery Lane when a motor that fell off so I was a little anxious when Wood Lane asked if I was having any problems and then a train technician got on at WHC to run a system check. Thankfully it was nothing to do with the train itself, the cover of a junction box had fallen off and got stuck underneath.

For the want of a nail......
