I have recently been able to get copies of some photos from the 1950's/60's in the great eastern area. I'm trying to identify one location witch has a searchlight signal (I guess 3 aspect as it in black and white) which has the code of 'RU'. The ole on the photo is of the later type, eg the Clacton branch if that helps. Can't find anything on it at all. Can anyone help?

Is this Phil Deaves Signal Box codes any help?

It has RU as Rossington, and RUM as Romford Up Main (?) automatics.

I can only help one person a day. Today's not your day. Tomorrow doesn't look too good either.

Thanks Andy. I did look at this site and found that the info didn't match the photo. I would post it, but i can't due to not being allowed to publish them.

There are 4 photos of the same station, with ole with only 2 wires, so it can't be on the routes that where at 1500v DC. There are only 1 set of lines in each direction. There are 2 locos in the photos, one is a Colchester b1, the other a Stratford b17.

I should of put this information on my original post.

Bit of a long shot but some areas were known to reverse the letters for bi-directional working, so RU might have been signal box code UR. Not Upminster perchance?

Thanks Geoff, but I'm nor sure about that as there's alot of green and there's no other lines apart from the up and down lines. Also, I don't think Colchester b1's strayed on the LTS. I've looked at some of the other pics and there's one of the same b1 with 3 lner non-cor's, at what looks like Clacton.

Just out of interest, when did the Clacton line electric services go live?

There was some early isolated test running of the 25kV system in the late 50's, while Chelmsford - Colchester was still not wired.
First trains given as March 1959

I've used that site a lot. East Gate Junction (Colchester), Wivenhoe and Thorpe-le-Soken all had the code "RU" for Up line automatic repeater signals and seems to be in the correct area for the locos mentioned.

It's not a code, it's a notation.

"RU123" means "repeater for U123"; we'd nowadays write that as "U123R". Similarly "RUM123" is "repeater for UM123".

On the GE, automatic signals were numbered like "UE12C", where "UE" is the line code ("Up Electric"), "12" is the mileage (so between the 12th and 13th mileposts), and "C" means this is the third or fourth automatic signal in that mileage (the first one wouldn't have a suffix letter and I can't remember if the second was "A" or "B"). The four track section to Shenfield was Main and Electric, that to Hackney was Fast and Slow; the six-track section was Slow, Main, and Electric. Two-track main line was just "U" and "D", but I think some branches had suffices (from memory, the Southend Victoria branch was "US" and "DS").

Given this arrangement, it makes sense to make the "R" a prefix rather than a suffix.

This system was used elsewhere. The "MU"/"MD" notation for wrong-direction signals was a Western innovation, I think.

Unless memory fails me (by no means impossible) I think it was 'Suburban' rather than 'Slow' lines out of Liverpool St and on to Hackney.

I think that was a consequence of the original nomenclature. Before Ilford Flyover was opened, the present Electric lines were designated the Through lines and the present Main lines were the Local lines (with plenty of conflicting movements in the throat at Liverpool St to keep the bobbies on their toes).
