I expect this has been covered before so apologies if that's the case.
Are there any of the 1990s Central Line Project dot matrix screens left in service and if so where? These had if I recall correctly a mix of green and orange LEDs for different purposes.

Speaking from the eastern end of the line, they are at:
Chancery Lane
Liverpool Street
Leytonstone
Redbridge
Gants Hill (I’m pretty sure)
Buckhurst Hill
also one at Ealing Broadway

I wonder why some (the majority) were replaced but a few of the 90s version have remained?
The replacements were a bit brighter but you still have to be near enough to read the text.
Were the replacements linked to the Metronet station refurbishments, back in the day?

Funny how each of the platform DMI's have different times however with neither showing the correct actual time! |

The old displays will always hold a special place in my heart

Well if you take into account that all of the stations that still have them avoided PPP refurbishment, thats a most likely reason. |

I think there are a few different dot matrix boards now in existance. I tried to link to third party photos of them but it didn't work. 1) The original 90s display (with green and orange LEDs) 2) A similiar proportioned display with all orange LEDs, that replaced some of the 90s displays (? in the Metronet era). As I recall, the 90s displays seemed to be working but were replaced anyway at many stations. The LEDs are a bit brighter. At around this time indicator boards also appeared in the ticket hall (which seem of very limited use, especially at Roding Valley)! 3) More recently, smaller ones such as those at Bank. I agree that these are too small to read - unless you are standing right in front of them. |

They would be so much better with white LEDs as being installed on National Rail stations.
Better still would be displays like those on the Elizabeth line.

These had if I recall correctly a mix of green and orange LEDs for different purposes. I think you mean these ... which I wish were still in service as the different colours were much more pleasing on the eye than plain orange - or red at one station (Edgware Road, subsurface, I think)  |

Yes, that's the style. Nice picture. For another possible use a colleague was asking about this style with 5 dot lower case body height and the upper case going above and below.
I had the impression that this style fell out of favour with certain people in LUL quite quickly because Metronet got a very dusty response when something similar was amongst the styles offered for D78 Refurb.
Anyway thanks again to all contributors to the thread.

There is also a pair at Hanger Lane.
There used to be some at Bank as well. The new ones are very small to read and are much worse than the screens they replaced.

Unfortunately as many of the replacement train describers are proving, compliance isn't necessary aligning with user friendliness. Numerous stations on the Central line benefited from good replacements from Data Display (now Daktronics) during the Metronet-era. Those that have followed since have on the whole not been so fortunate

There is also another very common style, for example at Oxford Circus Bakerloo line. Are these from the same era as the one in the picture? |

The newer DMI shown in xtmw's post was used by Tubelines (Jubilee, Northern & Piccadilly lines) during the 2007-2010ish station refurbishments. These DMI's were made by Infotech: www.infotec.co.uk/ |

Speaking from the eastern end of the line, they are at: Chancery Lane Liverpool Street Leytonstone Redbridge Gants Hill (I’m pretty sure) Buckhurst Hill also one at Ealing Broadway I remember when these were expanded out in the mid 1990's to suburban stations like Snaresbrook which never had any form of arrival indicators. Leytonstone had the bulb unit which would light up the next train destination, but obviously these would not give minutes etc. I wonder how these old things worked if it was by someone in the station, it hardly was ever wrong. |

Can't the DMIs be 'overrided' from the station control room?

I'd just be happy if they had enough, correctly positioned that you can actually read them from anywhere on the platform. Impossible to read the Gants Hill westbound one when you are at the other end of the platform getting on the front of the train.

Though, the Central is reliable for having accurate indicators (SSR Lines I'm looking at you!) There is the occasional moment where it will go blank, and display Westbound Trains: Central Line or something like that..

Presumably the logic in the display is responsible for those types of message, so they will show whenever there is a glitch in the feed. |

The ones at Liverpool Street have been doing that recently but haven't seen it anywhere else. |

) I have to say while I love the green text, I'm not a fan of the capitalised 'M' in 'Mins'. I mean technically it should be 'min' instead of 'mins' but I can't hold it against that particular style of screen, as all of them have done that ever since the 1981 trials at St. James's Park. I guess the TfL style guide hadn't been invented back then... |

Central Line in green is just plain wrong! It's been the red colour since Adam was a boy.

If the choice is green or amber, might as well use green.
I don't much like how the baseline of lowercase is raised, it almost works visually for the destination but not for "Mins".
