Thanks I assume with an MA and compressors in the saloon. Correct I assume. I recall seeing the compressors, not sure about the MA but I will check at some point.

Why do you say that? I remember seeing the 4 car west RAT unit towing 4 cars of 1992 stock before. Is it a logistics issue regarding combining trailer and motor car equipment?

I sincerely hope LU spends a few £ on the ability to run the trains under their own power from Ruislip to Acton ruther then all the b*gg*ration of splitting trains and running with the ancient relic/MPU. This would be good for the journey to Acton. However, there would be a risk in returning the 3-phase converted trains to Ruislip unless they are tested. Does anyone know whether the test track (27 road) at Acton will be retained?

Out of curiosity is there any reason why it's called MPU rather than the more traditional Pilot Motor (or even locomotive)?

Does the M not stand for 'Motive'? Wouldn't surprise me if there's a few different variations floating around, mind...

Were the 67TS modified to be compatible with the Central Line Signalling, which is a close descendent to the OLD Victoria line system??

It is light years ahead of the old Victoria Line system in terms of technology and is more closely related to the current Victoria line in that regard. The similarity between Old Victoria and Current Central was more in terms of (very) basic principles than anything else.

kkc35348 - perhaps you are getting confused with the former Woodford - Hainault installation decommissioned decades ago on which the 67ts did occasionally run.

A quick frequency conversion job sounds easy doesn't it. But these things are never "a few £s" are they. And maybe the new 92TS equipment doesn't need or have 125Hz compatibility, so then we'd be on to fitting proper new track circuits and then on to will those be needed at all with Picc Upgrade so is there any value? Oh dear!

There is no signal compatibility requirement for the MPU and Central line ATP. The 1992 tube stock will travel under its own power to Ruislip. From Ruislip, the MPU will take the half train to Acton under tripcock protection via the Ruislip depot to Met spur, and Rayners Lane. There had been speculation about running whole trains via Harrow on the Hill, the Circle and District where all track circuits are 'immunised', but I haven't heard the outcome.

Oh dear! From what I know of the 1992ts they are compatible with 125hz track circuits as they ran with them during the period the Central line was being resignalled. At one point I was involved with a feasibility assessment for converting the North Ealing to Rayners Lane area to 125Hz operation. With some careful design and planning it was probably feasible to do it over a series of weekend closures, but only if a radically different approach was taken when compared, say, to the 4LM method of Frequency conversion which was rather specific and required more invasive alterations.

Hi, yes I was aware 92TS is compatible with 125Hz, I was just postulating that the replacement package might not need to be. A cheaper method of frequency conversion of the route sounds interesting. I wonder if that's what was value assessed against the 4 cars at a time, hauled approach. And regarding the other route via baker St and the Circle, it still includes some 125Hz tracks if I recall correctly. And in any case, the Thales ATC commissioning should be happening in time to rule out frequent passage that way of trains only having tripcocks or Central line ATP. Or is this 92TS job going to happen really fast?

I believe because all 4 cars are powered/motored. I have photo of it in 2014 being shunted at Acton town and it is a two car unit. and this the photo. FISH7373 81C NFP

The total value looks wrong to me. £1.8m is far too low, and if it's out by a factor of 100 then it's £60m higher than in the press release.
