Hi all - longtime lurker, first post Can anyone tell me about this porcelain insulator pot? I found it during a recent bat survey in the 'up'/northbound tunnel at Highgate High Level, at the East Finchley end, but I'm not sure this tunnel was ever electrified. I saw another pot, on the floor of the parallel tunnel, in much worse condition as the tunnels are damp. I have read some confusing accounts of shunting '38 Stock from Highgate to Finsbury Park for the Drayton Park line in the 1960s, but it's not clear to me.
this is where I found it: here it is - does anyone recognise the maker's mark or understand the ref number? the date is 1957.

A proper welcome to you, @smnmy . The makers mark on your insulators is that of Bullers Ltd which merged with Taylor Tunnicliff a year after the date of manufacture to become Allied Insulators which today still supply London Underground and NR with power supply components including 3rd & 4th rail insulators. The video footage I’ve seen of the area in 1961 shows that the platforms of Highgate High level were not electrified but that four rails did extend to Park Junction (divergence point for Alexandra Palace) and that the Northern extremity of the Southbound tunnel formed part of a shunting neck for Highgate Wood Sidings which is why it was electrified. Photo below showing a BR suburban service traversing Park Junction enroute to Alexandra Palace with the Northern line depot in the background and the electrified Southbound spur just visible in the foreground. .jpg) www.disused-stations.org.uk/h/highgate/approaching_park_junction_last_day(aa_jackson).jpgHope this helps, G.Arrow |

That was done using battery locos - here is such a transfer in passing through Crouch End 23.jpg) (it's running "wrong line", so the loco is at the far end of the train) After the ljne was dismantled in 1970, transfers were made from Neasden, via the "Widened Lines" and the "Hotel Curve" at Kings Cross |

Thanks - all makes sense now! i noticed the Allied ones are pretty much the same, so that explains that too. |

That's what I love about this site. An obscure and highly specific question like that gets a comprehensive answer within about 90 minutes, I think it was. God bless DD!

@smnmy , Just found the perfect shot here. Looking South towards Highgate (High level) from Park Junction showing the extent of the fourth rails towards the tunnels. I'd known about this photo for a while since the telegraph pole insulator you can see on the left hand side was gifted to me as a paperweight from a family friend who had worked as a surveyor when the permanent way in this area was dismantled. Incredible that there are still remnants of this hanging around decades later. Taken in 1956, published on Flickr by Owen Smitherswww.flickr.com/photos/17889585@N03/3527305705/ |

I'd seen photos of the bomb damage but it's only now that I can piece the info together. |

Some of the Northern Heights route was fitted with four rails but not conclusively. I found a photo of Cranley Gardens with the risks in place. Thanks for this too! I think I'll have to check out 'Northern Wastes'. |

Many years ago, a few weeks after first moving to London, I managed to get into these tunnels and walked through (in the pitch black) to the old Highgate stations. It was a fascinating day's urban exploration.
