It's New Year's Eve, and Bank station is closed, the Waterloo & City line suspended. Management tell the signaller on duty to send a train to Bank, carrying the precious cargo of a DSM and half a dozen "station staff". Half and hour later, the station re-opens.

Surely the company has not worked out a way to familiarise staff with the largest station on the network in just thirty minutes?! Of course not, the mere suggestion is ridiculous.
