I caught a train from Great Portland Street towards Paddington this evening at around 630. The train and PIS both said Hammersmith. After leaving Baker St the displays changed to say it was a Circle Line train via High St Kensington, which caused a lot of confusion at Edgware Road. There was a few minutes delay there, after which the driver announced the train was going to Hammersmith
How does that happen? Is that a bug in the system or would the control room have needed to change the destination both times?
