Ill post a few more pictures but can anyone identify this piece of kit please.
It was part of the system used to throw an old set of points located near Amersham on the Metropolitan Line, so we've been told. |

Do you have any photos without the black bags hiding things ?

That looks like a slate board and the fittings appear to be those of a traction section switch. If associated with a set of points I expect that the points were for a siding and that this pile of scrap once upon a time was the siding traction fuse circuit breaker.

For some reason, the photos reminded me of when I was in Deptford a couple of months ago and came across the Thrift Market off Deptford High St. Anything and everything on sale, that mostly looked as if it had been salvaged from skips. Interesting, but generally expensive!

Unfortunately no other pictures, just these were sent to me.
We'll pick it up anyway and see what we have, if it's scrap then nothing lost....

Not the same thing, but similar looking 630v equipment: click on the photos to enlarge  Disused equipment in trackside building at Golders Green. Believed to have been associated with Traction Control. Taken at night after close of traffic. Unfortunatley the light in the room wasn't working and so I didn't find out until too late that I hadn't got it all in the photo!  Rear of sising circuit breaker - I think it was Tooting Broadway, but Tooting, Kennington and Archway are all the same. The manual (pole) operation and + / - breaker blades with arc shields are on the other side.  Close up of the bottom half of the rear, clearly showing the positive / negative in / out traction connections and some of the low voltage control equipment at the bottom (there is more LV equipment on the front). |

Interesting top picture looks like a traction circuit breaker and on the wall to the right I believe the yellow boxes are track recording voltmeter transmitters. |

It's a pity I didn't have a photo of the front or photos of anything else in the room (I've looked, and that photo was the only one I took in that room). The photo was taken during a night trackwalk. I should have gone back during the day and taken some more photos and taken photos in the other rooms. From what I recall, the room (in a small trackside building) wasn't much bigger than an outside toilet and just had the one piece of equipment in it. It's possible there was traction equipment in the other part of the building.

Reading up on some notes that I did, I see that the building was the Depot Switch House (I should have remembered that!) that switched traction current. There are two substations at Golders Green - one for the running line and one for the depot. According to the diagram, the switch house contained a circuit breaker (normally open) and a changeover switch (possibly open, as no default position shown). Both positive and negative would have been switched. The changeover switch was fed from either directly from the running line substation or from the Golders Green to Belsize Park SB traction current section (via the current rails). The centre of the c/o switch went to the circuit breaker and the other connection from the circuit breaker went to some of the depot roads and the two shunting necks. In turn, these were connected to the depot substation via a section isolating switch. This arrangement gave flexibility in an emergerncy, such as the loss of one of the substations. E.g., in the event of the depot substation failing, after performing any necessary isolations, the circuit breaker could be closed to allow the running substation to feed the entry part of the depot. Although it was on the current Controller's diagram at the time (2007), it was obvious that the switch room equipment had been abandoned and so I omitted it from further notes and diagrams that I did. It's quite possible that, under the traction current system upgrading, it was simply decided that the emergency connection facilities were no longer required. switch house traction current connection arrangements  |

Apologies for not replying sooner.
Thanks for the information, looks very much like the bit of kit we.ve been offered.

Probably of little use 'as is', even were it to be in first class condition, on a line without a traction supply. However, any and all parts may be useful 'spares' for something as long as one has available storage space. |

It would make a nice light switch  |
