RMweb Premium PaternosterRow Posted April 17, 2012 RMweb Premium Share Posted April 17, 2012 Can anyone tell me where, apart from Farringdon, did overhead and third rail meet. Would they have run side by side by Clapham Junction say? Link to post Share on other sites More sharing options...

10800 Posted April 17, 2012 Share Posted April 17, 2012 A number of goods yards on the Eastern section of the Southern - Hither Green, Hoo Junction, Shepherdswell etc. Link to post Share on other sites More sharing options...
Edwin_m Posted April 17, 2012 Share Posted April 17, 2012 A number of goods yards on the Eastern section of the Southern - Hither Green, Hoo Junction, Shepherdswell etc. Just to stop any hares running those were 750VDC OLE, installed in some goods yards before the advent of electro-diesels because third rail would have been dangerous to staff on the ground. Also platforms 9 and 10 at Euston and two approach tracks out as far as Camden, where the Euston-Watford DC service uses the same tracks as the 25kVAC trains. There used to be a bit of third rail in one of the main line platforms at Watford Junction so the 313 units could change power on the way to and from their depot at Bletchley. Were there ever any bits round Willesden Junction low level? (none shown now on the Quail map). Talking of 313s, we mustn't forget Drayton Park.

Southernboy Posted April 17, 2012 Share Posted April 17, 2012 Yes, at Clapham Junction 3rd rail and OHLE ran side-by-side (along with steam), I believe this was also the case at Wimbledon, and possibly at other junctures where LBSCR and LSWR lines ran alongside each other. Actually, at Wimbledon the 4th rail District line service also terminated - adding another dimension to modelling traction potential in one scene. It's a scenario I would love to model one day Link to post Share on other sites More sharing options...
RMweb Gold big jim Posted April 17, 2012 RMweb Gold Share Posted April 17, 2012 Here is an obscure one, crewe electric depot "platform siding" there is a short length of 3rd rail under the ohle in there, only energised as required iirc Link to post Share on other sites More sharing options...

Suzie Posted April 18, 2012 Share Posted April 18, 2012 Bury Bolton Street must have had at least one dual platform before the Holcombe Brook branch had the 3600V DC overhead replaced with1200V DC third rail Link to post Share on other sites More sharing options...
Nick Holliday Posted April 18, 2012 Share Posted April 18, 2012 I'm not sure if the OP was referring to the LBSC overhead electrification of the 1920's, but it didn't extend to Wimbledon, so it only ran side by side with the LSWR third rail from Clapham Junction before it turned away to Victoria. However, during the changeover to third rail the two systems ran over the same lines. Link to post Share on other sites More sharing options...
roythebus Posted June 13, 2012 Share Posted June 13, 2012 There's OHLE,3rd rail and 4th rail at Wimbledon today with Croydon Trams. Stratford and the Central Line, Farringdon, LTSR and the District Line; in the "old days" there were various connections across the DR tracks to serve various factories on the DR side.

adanapress Posted October 7, 2012 Share Posted October 7, 2012 A train going to, say, Willesden Junction High Level from Gunnersbury , is on fourth rail for a few hundred yards after leaving Gunnersbury (which provides a reversing facility for LT trains in times of 'service perturbation') then a short distance of third rail running through and just beyond South Acton (which in LNWR days was 4th rail for their service to Kew Bridge!) followed by OHLE AND third rail at Acton Central for AC/DC change over. Must be quite a few immunisation problems thereabouts. Theres also some interesting bits just south of Willesden Junc. Low Level, where the southbound Bakerloo lines have juncs (left turn) to the N London lines and also (right turn) into Depot, within which there are oddities, or so it seems from Quail). I think theres also OHLE meeting fourth rail end-on (but not connecting physically) at Upminster. Also a bit of 750 OHLE used to exist in Stewarts Lane depot, a line right up against the viaduct.wall, or so think I recall, but it was a long time ago.

RMweb Premium phil-b259 Posted October 7, 2012 RMweb Premium Share Posted October 7, 2012 Here is an obscure one, crewe electric depot "platform siding" there is a short length of 3rd rail under the ohle in there, only energised as required iirc Presumably installed for the benifit of the new class 92 locos, all of whose depot allocation was Crewe (despite the fact that for many years they had to be draged dead from the to Dollands Moor because of the delay in getting them acepted by Railtrack) Link to post Share on other sites More sharing options...

David Hibbert Posted October 11, 2015 Share Posted October 11, 2015 Can anyone tell me where, apart from Farringdon, did overhead and third rail meet. Would they have run side by side by Clapham Junction say? Between Euston and Watford Jct and parts of the North London Line. I expect they did on the Southern in various places.

David Hibbert Posted October 11, 2015 Share Posted October 11, 2015 how 'bout oop north, between allerton depot and hunts cross in liverpool, there is a chord from the wcml onto the 3rd rail merseyrail network Between Euston and Watford Junction, parts of the North London Line and in North Pole Depot and its connections towards Kensignton as well in the Liverpool area. Also in the freight yard approaching the Channel Tunnel. Cross Rail will also have some at Abbey Wood. The area from Acton Central does experiencedc corrosion problems, and the OLE mast bases have special insulated base connections.In Selhurst depot there is a short length of OLE for testing Class 319's. Note that when both systems are dc there is no corrosion problem. Additionally there are a number of places where 3rd/4th rail tracks run adjacent to OHL lines.

David Hibbert Posted October 12, 2015 Share Posted October 12, 2015 Has anyone got any OLE layout plans of Southern 750 V d.c. that I could obtain copies off please? Link to post Share on other sites More sharing options...
Nearholmer Posted October 13, 2015 Share Posted October 13, 2015 DH No plans, I'm afraid, but it was very simple "tramway" wiring, suitable for low speeds and currents, so not too challenging to model from photos and "standard practice" I would think. For completeness, there were bits of it on the Central Section too, pre-dating the Eastern Section bits, having been installed for the benefit of the 'Hornbys'.

10800 Posted October 13, 2015 Share Posted October 13, 2015 They were just done as test beds (at Balcombe and Lover's Walk). As I understand it the Central section then went for third rail in the arrival and departure roads only, leaving the main shunting areas unelectrified for steam and diesel shunters.

Judge Dread Posted October 13, 2015 Share Posted October 13, 2015 I did in a moment of madness build an EM layout called Brockley Green SE4 which had the OLE in the parcels depot and coal yard. I only had one loco, a DC kits class 71 to run on it. After 6 years exhibiting in 6 countries, 26 shows and 9,800 miles, I sold it to a GWR fan in North Somerset. The 71, however runs now as a 00 loco on my present layout Meopham East Junction. Link to post Share on other sites More sharing options...
Nearholmer Posted October 13, 2015 Share Posted October 13, 2015 10800 - agreed. Suzie - do you know anywhere on the web where Holcombe Brook is described in detail; I only came across it in an old RM recently, and it looks like a fascinating little station/branch?

Suzie Posted October 13, 2015 Share Posted October 13, 2015 There is not much info about the electrification. Most references are an aside to the Bury line which used the 1200V DC third rail system that was later used on the Holcombe Brook line. Google will find a few snippets. Here is one with some nice pictures:- http://www.lyrs.org.uk/Electrification Another here:- https://www.railscot.co.uk/page/buryholcombebrook The single line portals used for the overhead were quite distinctive but I cannot lay my hands on the picture.
