Are you sure of that? I thought I remembered reading about it (as a current event) later in the 1980s; the Friends of Alton Station website says 1985; and in this cab ride video from 1988 much of the disused track is still in place.

I'm pretty sure that Moreton-Dorchester was singled before it was electrified, so no third rail reduction at all.Farnham-Alton singled 1980; Moreton-Dorchester singled 1985.
Farnham to Alton was singled on 21 July 1985, and the loop at Bentley opened on 24 November 1985.Farnham-Alton singled 1980
not third rail, thoughMoorgate-Farringdon (Widened lines)

That was wired at 25kV AC overhead, not third rail.Moorgate-Farringdon (Widened lines)
Pedantically, wouldn’t those have been fourth rail rather than third rail?London Underground lines-

The singling took place in 1985, bizarrely it was on a Monday after the morning peak. My last train of ballast for the track reinstatement from Alton to Medstead was booked to run that morning, but was stuck in Woking Yard for weeks until someone could work out a pathway.The singling in 1980 had no intermediate loop: the loop at Bentley was only added in 1987. Holybourne Siding had been added in 1986.
If you're going to be doing 'mass balance equations' then you need to allow for the extensions of third rail in the not too distant past.Apologies if this is not posted in the right category. I have been wondering for a while how many track miles of UK railway have been removed (or converted to OHLE) over the years, that were already 3rd rail electrified.
Lines that spring to mind are:
* Copyhold Junction to Horsted Keynes
* Folkestone Harbour Branch
* Elmers End to Addiscombe
* West Croydon to Wimbledon (became Croydon Tram)
* North London Line (various parts converted to OHLE)
If a system of 'trading miles' (old for new) was allowed, would there be enough miles of new 3rd rail lines to cover 1 or more of the diesel islands south of the Thames?
If you take it to the logical extreme, you'd say there should be almost none at all, because very few stretches of track were built with third rail from scratch.If you're going to be doing 'mass balance equations' then you need to allow for the extensions of third rail in the not too distant past.
Stratford to Canning Town went over to the DLR (so a different form of 3rd rail), Canning Town to roughly Silvertown became part of Crossrail (OHLE) while the final part of the line to North Woolwich closed completely.The NLL as stated elsewhere in this thread was 3rd rail in its entirety from Richmond to North Woolwich. (The 4 track section from the ECML to Dalston used to have 2 lines of OHLE and 2 lines 3rd Rail with other parts being dual electrified (Camden - Stratford section springs to mind)). The West London Line (Willesden Jnc - Clapham Jnc) wasn't 3rd rail until Eurostar came to town and the juice rail was extended from Clapham to North Pole. ( I travelled on both lines in the 80's, 90's and early 00's). I haven't been on the Stratford - Custom House - Woolwich section since it went to DLR and I can't add dates to when the changes took effect as they were all observations when out spotting on Travelcards or Rovers.
Pedantically, if there were four rails there must have been a third one.That was wired at 25kV AC overhead, not third rail.
