Nearholmer Posted August 31, 2015 Share Posted August 31, 2015 ForestPines Do note the word "intended" in what I wrote ......... Because, you are right, maintaining even a few ohms rail-to-rail over the length of a track circuit can be a real challenge, and failure to achieve it is the cause of many a "signal failure". But, solidly earth one of those rails, and hundreds/thousands of amps of traction current will go wandering off all over the place, by every path it can find, looking for other, perhaps accidentally earthed points on the rails, by means of which to "get home" - chewing metal as it goes.

Ray Von Posted August 31, 2015 Author Share Posted August 31, 2015 Cheers FP, very interesting info- controversial too I expect! What a can of worms.... Particularly grateful to Keith for that video, thanks a lot. :-) *edit sorry Kevin we posted at the same time ish! Link to post Share on other sites More sharing options...
pete_mcfarlane Posted August 31, 2015 Share Posted August 31, 2015 Never heard that one...what types were banned because of that reason? The only locos I've heard of being banned from the third rail system were the early English Electric diesel shunters with 4 foot driving wheels (class 11 and similar). The outside coupling rods got a little too close to the conductor rail. Link to post Share on other sites More sharing options...
Ray Von Posted August 31, 2015 Author Share Posted August 31, 2015 Interesting Pete, would class 08/09 be included in that? Ray. Link to post Share on other sites More sharing options...
pete_mcfarlane Posted August 31, 2015 Share Posted August 31, 2015 No, they all had larger driving wheels (4'6") to give enough clearance to run on third rail lines. Link to post Share on other sites More sharing options...
Ray Von Posted August 31, 2015 Author Share Posted August 31, 2015 Cheers Pete. This thread is all my Mrs's fault (God bless 'er) So, on my 1978-82 Canterbury / Thanet layout, I could run a hypothetical steam loco service once in a while? Colour me excited! :-) Link to post Share on other sites More sharing options...
RMweb Premium newbryford Posted August 31, 2015 RMweb Premium Share Posted August 31, 2015 Never heard that one...what types were banned because of that reason? Certain "modern" trains were (are) also banned from SR 3rd rail territory. In particular HST stock fitted with long swing link BT10 bogies. Short swing link stock had to be used when traversing Bournemouth for example. That's particularly why the NMT HST doesn't visit the Southern region - it has long swing link bogies on the intermediate vehicles.

Ray Von Posted August 31, 2015 Author Share Posted August 31, 2015 VERY interesting Mick, I was thinking of (in pure fantasy) running a 125 thru my station - for fun, it'd be too long to stop - but being in the deep south, I suppose even this is too far fetched!? What do you think of my occasional steam service idea though.....? :-) Link to post Share on other sites More sharing options...

(Rule 1 applies and I certainly won't be checking to see if your modelled coaches are SSL versions.........) Crack on. Cheers, Mick Link to post Share on other sites More sharing options...

Ray Von Posted August 31, 2015 Author Share Posted August 31, 2015 Ruddy hell, The Southerner- That was inspiring footage! Thank you so much for that, maybe the 125 will pass thru my deep south station in 1980.... Link to post Share on other sites More sharing options...

Ray Von Posted August 31, 2015 Author Share Posted August 31, 2015 Edit - Birmingham to Ramsgate, probably the service would terminate there and not see the bright lights of Margate! :-) Link to post Share on other sites More sharing options...

Fat Controller Posted September 1, 2015 Share Posted September 1, 2015 Already been done. Birmingham-Ramsgate regular service Cheers, Mick I think it ran beyond Birmingham, perhaps to Manchester, as we used it to return elderly in-laws to Stoke to avoid them having to change trains in London. I recollect we took them to Faversham to board it, and that father-in-law (by then in his 80s and deaf) complaining about people keeping the windows open all the time.

phil gollin Posted September 1, 2015 Share Posted September 1, 2015 . I've always wondered about steam locomotive injectors. To set an injector going a fireman used to run the water through (which ran out through a tube onto the track) and then turned on the steam to (with a bit of luck and skill) get the injector working and stop the stream of water. I've always assumed that the injector pipes must have been angled to avoid the normal position(s) of the third rail ?????? Does anyone know for sure ?

Zomboid Posted September 1, 2015 Share Posted September 1, 2015 There's no particular issue with spraying water on the third rail. It does rain from time to time after all... Though saying that I doubt the SR would have pointed them directly at it, it certainly won't help with corrosion and the like. Link to post Share on other sites More sharing options...
Ray Von Posted September 1, 2015 Author Share Posted September 1, 2015 Cheers chaps, all very useful information! I think Phil's got a point, what's to stop the electric current traveling up the jet of water from the injector, and making the whole train live? FC, do you recollect what year(s) you saw that service to Manchester via Faversham, was it around the same time as Micks picture? Link to post Share on other sites More sharing options...

If it were then rain would be a major problem. Link to post Share on other sites More sharing options...

FC, do you recollect what year(s) you saw that service to Manchester via Faversham, was it around the same time as Micks picture? It was a few years later than the photo, as we didn't move down here until 1991. It was whenever Virgin still had the Cross-Country franchise (just checked Wikipedia, 1997- 2007); the Ramsgate service apparently ran for the last time in September 1999, so it was quite possibly then.

Ray Von Posted September 1, 2015 Author Share Posted September 1, 2015 Cheers FC, How regular was that service, and was it always pulled by a Deltic? Can't believe that I never saw it, as I was a regular commuter on that line in those days, and the Margate - Ramsgate line passed my house... Thanks again, Ray.
