Back in January signs appeared at Northern Line tube stations advising that during the morning peak, all northbound trains on the Bank branch would go to High Barnet, and all northbound Charing Cross branch trains would go to Edgware*. Today they've put out a cryptic press release hailing its success:
A series of changes to the Northern line schedule, the product of over a year of detailed study, has resulted in more trains running on time. Modifying the service in response to increasing customer demand has led to increased reliability and has reduced journey times by around a minute.Interestingly they manage to ramble for 400 words without once mentioning what the major change is. The thing I find interesting is they could have used this as an opportunity to butter up the press for the probably upcoming full split, but have instead chosen to say nothing of substance.
(* actually each sign only mentioned the arrangements for the branch the station was on. Can't have the passengers knowing too much)
