I was just to go out on site last night and decided to check the engineering notice of the night and I noticed that there was a stock move from Golders Green to Northfields of a 95 stock train. It was however cancelled as I learnt later in the evening (as I was at GG), however I have never seen, or knew, this stock move can happen. What would be the reason for it and can the 1995 stock negotiate the South Ken curves?

That would have been for brake testing on the South Ealing test track.

can the 1995 stock negotiate the South Ken curves? Presumably it can, unless that was the reason the move was cancelled. 1995 stock 17.77m x 2.63m 1973 stock 17.68m x 2.63m That extra 9cm length might make the difference but at dead slow speed it would probably fall within the dynamic envelope (the extra clearance allowed for swaying) of a 1973 (which also has to allow for changes in weight in service that an empty move would not) According to CULG 1995 stock cannot run on other lines because of incompatibility with he signalling equipment, so it would have had to be towed |

Why would it need to be towed? The incompatibility would be to do with TBTC surely, and unless tripcocks have been removed (which, thinking about it, they probably have), it would still be able to use conventional signalling. Besides, if the movement was carried out under a possession, then it wouldn't have mattered at all as it would be the only train on the line.

Wonder if the 62ts Pilot/Sandite unit is still compatible with towing 95s around?

The move was to have been carried out in a possession under its own power. The 62TS unit could tow the 95TS, but that would add unnecessary additional movements.
Not sure on the exact reason for the (second) cancellation of the move, but there was a gauging requirement before it could take place - although the 95TS have used the eastbound road before (on delivery), they haven't used the westbound.

That would have been for brake testing on the South Ealing test track. A few thoughts, can't say for definite as on leave at moment. I wonder if the testing is connected to the plans to run at 100kph on certain sections of the Northern. 95 stock now has had its tripcocks removed, so no possibility of running under old signalling. I don't think gauge would be an issue as 96 stock has been taken to and from Highgate via the Picc line, boxed in with battery locos on each end. Obviously relevant paperwork would need to be signed off for 95 stock though. |

Testing is in association with a speed increase and to validate a method of doing wet rail testing on the Northern Line. Tripcocks will be refitted and the train move under its own power. 95TS profile is very subtly different to 96TS and the secondary suspension is different therefore the gauge checking has been required. The software takes a long time to go through it all and any infringements have to be physically checked etc.

Dan

very interesting that train can fit in Piccadilly line with no ATO operation

The 95TS unit was refitted with tripcocks for the journey and ran in tripcock mode. Remember they did this regularly until relatively very recently. The move was also in engineering hours though, meaning no requirement to fit in with service trains.

As has been pointed out above, we already have a thread on this. I've locked this thread and will merge the two later (currently on a steam rally field). Threads now merged.

This (Finally!) ran last night. Here's a few snaps of it arriving at and departing from King's Cross (Piccadilly) just before 0200. What exactly happened here? I initially assumed it would be a simple matter of Euston southbound Northern line (city branch) platform 6 - Euston loop - King's Cross loop - King's Cross St. Pancras northbound Piccadilly line platform 6 - southbound Piccadilly line via the crossover. But looking at the pictures (specifically, which unit is leading into a Piccadilly line platform at King's Cross), it doesn't look like that's what happened? The 95TS unit was refitted with tripcocks for the journey and ran in tripcock mode. Remember they did this regularly until relatively very recently. The move was also in engineering hours though, meaning no requirement to fit in with service trains. I thought they'd also removed a number of tripcock mode indications etc. in the cab, such as the tripcock delay light? Was it really as simple as all that - just refitting tripcocks - or was it a more complex job? |

But looking at the pictures (specifically, which unit is leading into a Piccadilly line platform at King's Cross), it doesn't look like that's what happened? That looks right to me - the train had to reverse in platform 6 first picture shows 51720 leading into the N/b platform, right road second picture shows 51680 in the n/b platform, the driver having changed ends. third picture shows 51720 on what is now the rear of the train, leaving platform 6 "wrong road" as the train approaches the crossover . |

Nice one Jack. This is the sort of thing that keeps me interested.  |

that's was amazing so they did without needing tow? - that's reason 95/96s can use certain routes if they are fit
