Passing on the inner circle a couple days back, I noticed R2250 not showing any aspect. Passing by it today, I noticed it was still not showing any aspect. This has got me thinking about two things. When do LUL replace burnt signal bulb?. And what actually is the function of R2250? Im assuming (since I cant remember the starter signal number) it repeats the outer circle starter signal at Farringdon, but whats the point of such a signal when trains all stop at Farringdon? Any insight/"logic" behind R2250, would be appreciated  |

R2250 is a repeater for signal A2250 which is itself a draw up signal for the eastbound station starter A225. A2250 is located just past the crossover less than halfway along the eastbound platform.

If a Repeater is on the same post as a Running Signal showing a Red aspect the Repeater signal will be suppressed ie no aspect will be shown
I don't know if this is the case for this specific signal

Here is the signal in question, as shown in a screenshot taken from Video 125's Driver's Eye View video.  And here can be found a picture showing the signal it repeats www.flickr.com/photos/crashcalloway/16167848212/ |

Ah! Ive never noticed A2250! Thanks for that. The number code did seem to imply it repeated a draw up signal, but I never knew it was there. Thanks for that! |

A2250 is a strange signal, it has no green aspect. There's an old thread about it here where you can read more about it: districtdavesforum.co.uk/thread/1425/a2250-farringdonAnd here's a detailed picture of it www.flickr.com/photos/24772733@N05/6235040565/ |

No indeed, why just one station away at Barbican there's one, isn't there? A2320.

Yes, but it's on the inner rail.

Interesting that the photo shows the conductor rail on the platform side!

Interesting that the photo shows the conductor rail on the platform side! As far as I can tell, thats because the points crossing from the inner rail to the outer rail, take up the space in the 6 foot meaning the outer (positive) conductor rail cannot be layed away from the platform edge. If you observe carefully, you can see that there are raised board on either side of the positive conductor rail to partially protect any person that falls on the tracks from making contact with the live rail. Either way, the positive conductor rail is only on the plaform side for the length of the points, and then goes back to being away from the platform. Hope that makes sense... Also, does anyone know the number of the points, I cant seem to remember. |

I wonder if A2550's earlier history has to do with the long, long, gone facing connection at the western end of the Farringdon platform, Outer Circle right across to the Widened lines

A2250 was only installed circa 1998/9, many years (decades?) after the connection to the widened lines was removed. |
