It's good to know that not every heritage feature on the London Underground has been ripped out and replaced by something plastic, modern and accessible. Not yet, anyway. Here's a mighty fine example, seen somewhere on the Hammersmith and City line.
This is the bottom half of the big sign in the ticket hall at Barbican station, at the top of the stairs down to the platforms. But where's the pink Hammersmith & City line gone? It appears to exist only as a bolt-on panel just below Barking. And that's because this is a pre-1990 sign, before the H&C was introduced, back when the Metropolitan line used to go all the way to West Ham and beyond. Nowadays the Metropolitan line terminates at Aldgate, and the Hammersmith and City has taken over the old route out east.
And there's more. The orange of the East London line is missing too. Prior to 1990 the track from Shoreditch to New Cross and New Cross Gate was part of the "Metropolitan line - East London Section". That Metropolitan purple stretched everywhere in those days. No longer. And Shoreditch station isn't open any more, and Canada Water station (apparently) hasn't been built yet (it ought to be between Rotherhithe and Surrey Docks Quays). This sign just doesn't reflect 21st century reality.
And there's more. The Docklands Light Railway appears to exist only as a connection at Bow Road (via another bolt-on panel). It ought to get a mention at Shadwell too, and probably at Tower Hill, but it doesn't. No matter that the DLR's been open for 20 years, it barely gets a look-in on this sign. Ditto the 1999 Jubilee line extension, which ought to have a connection at West Ham, but doesn't.
This sign is at least 20 years out of date, and quite possibly 30. The network depicted on this sign no longer exists. Several new lines, new connections and even new stations are not included. Any visitor to London relying on this sign for accurate transport information is being seriously misled. This sign is, quite clearly, wholly unfit for purpose. And yet it hasn't been replaced, and it hasn't been significantly updated, and it remains only because nobody quite has the heart to replace it. And I for one am delighted by that. Thank goodness that there are still people working for TfL who have a sense of heritage, rather than a passion to modernise. And let's hope that this tiny corner of Barbican station stays safe from the ravages of the evil redesign barbarians for at least another 20 years.
