Evening all, I was attending the Acton Depot Open Day, and I purchased what I'm assuming is a signal plate. I was wondering if any of you had an idea of where is from?  Many Thanks, Raynerslanemainman |

I'll check when I get home Monday but my initial gut feeling is on the EB line Alperton - Park Royal area. May possibly be on another line though. Watch this space.

That plate should be yellow if its a repeater, but it looks white to me.
Its an additional repeater for A527 (Wherever that is) as dictated by the 2.

Thanks reganorak That plate should be yellow if its a repeater, but it looks white to me. Its an additional repeater for A527 (Wherever that is) as dictated by the 2. The plate is yellow, but it is faded, I thought it was a repeater. Thank you both  |

A527 B is the inner home on the eastbound at Alperton, and it has two repeaters, of which R527 B(2) is the second. There was at least one other A527 B signal on the underground approaching Kilburn on the southbound Bakerloo from 1938 to 1984, but the arrangement of repeaters there was different. |

I thought it was a repeater. You can tell it's a repeater by the yellow plate (generally, see below) and by the leading R. Since the R is followed immediately by a number, you can tell it's a repeater for an automatic signal, here - as Harsig says - A527 B. If it were a repeater for a semi-auto, the R would be followed by the full identification number of the signal it repeated, including the cabin code. E.g.: RNQ3 repeated NQ3 - a controlled signal. "NQ" was the cabin code for Finchley Central and NQ3 was the southbound home signal on the High Barnet branch. That plate should be yellow if its a repeater, but it looks white to me. Its an additional repeater for A527 (Wherever that is) as dictated by the 2. In general this is true, although some (all?) of the original District Railway repeaters had white plates, e.g. RWG13 (WG13 is between Putney Bridge and East Putney on the west and is the last of Earl's Court's signals) has a white plate still (unless they've changed it recently): link |

I guess it makes sense to have two repeaters on such a tight curve into Alperton.
