Late one August night, BTP report to Paddington SS that there's an unattended bag heading north on the Bakerloo. (Hang on, why didn't the BTP deal with it? They are, erm, the Police, after all.)
Anyway, the SS tells Line Control, who plan to get it checked at Queen's Park. But Line Control has a bit of a problem getting hold of anyone at Queen's Park (sorry, did someone say "stations destaffing"?!). But rather than hold the train and wait, or get the police/bomb squad down there, what does the Control Room do? Tell the driver to press ahead to Willesden Junction and they'll get it checked there.
Good job that (a) Queen's Park station staff did manage to get to the train and check it; and (b) it wasn't a bomb. Otherwise there might have to be a proper investigation.
