RMweb Gold The Stationmaster Posted January 24, 2021 RMweb Gold Share Posted January 24, 2021 51 minutes ago, Donw said: According to my Father in law the coach he was in glided into the platform unassisted. However he did not say whether the main train had gone through the platform road or the centre road. A lot depends on whether the interlocking would allow the signalman to change a turnout between the train passing though. I imagine the signalman might be able to throw the levers quick enough especially if an economical FPL (i.e only one lever) was used. However I think changing a turnout in front of a moving coach would not be acceptable. What if it jammed. Of course from my Father in Law's point of view the Express would have cleared either the platform or the centre road before the Slip was close enough to see. This was at Reading with a Slip off the up Torbay Express not sure if he mentioned the date but it would have been before 1942 when he joined the RAF to become a Lancaster ground crew member. If you build one using DCC. You need to set the acceleration CV so there is no delay in reaching speed (or else the coach will appear to speed up) and iff using say the Zimo immersive drive where it will coast and you press F2 to break it will be a close replica of dribving the real coach by using the break. Sounds fun. Don PS Staionmaster Mike may have a better idea if the interlocking would have allowed the turnout to be changed with an approaching coach. PPS this had been flagged up to me by the system as something was updated I didn't notice the date. I see Mike did give a clear answer about slipping distants. It was not permitted, even if it had been physically possible (which it wasn't - see next sentence), to alter points between the passage of the main train and the slip portion. The Rules and signalling Regulations required than no stop signal reading through facing points be replaced to danger until the whole of a passenger train, complete with tail lamp, had passed beyond those facing points - and of course the original tail lamp was on the slip portion 1 3 Link to post Share on other sites More sharing options...

The signalman might often be waiting for one movement to take place before another can start. If the signal for an arrival is still off, the points it will traverse are locked, so if he is over-hasty and tries setting up a conflicting movement prematurely, the locking will do its job and stop him moving the points under the arriving train. Where points are locked by track circuits however, there may be nothing to stop restoring the lever once the points are locked by the track circuit.

Apart from good practice and observing the requirements of the Regulations that where facing points are involved the trains is required to have passed beynd the points before teh signal is returned to danger. Old provisions die hard it would seem although it is good signalling practice as it dsscourages people from attempting quick restiing of things ready for the next move.

RMweb Gold The Johnster Posted May 9, 2021 RMweb Gold Share Posted May 9, 2021 Or an auto trailer. I suppose one could install a powered bogie into a proper slip coach and control it's decelleration into a station to a stop with DCC, and possibly have it not coupled to the train but geared to be faster than the train so that it looked coupled but was actually pushing the train along. The main train is left running at it's normal speed but the chip in the slip coach can reduce the current to it's motor so that the slip falls behind under control. Given the linear spatial compression of most layouts, it would probably be more realistic to just have the main train appear on the layout, run through, and then dissappear back into the fiddle yard at line speed, and then 'drive' the slip into the station about 30 seconds later. As high speed slips took place about a mile out, you would need a scale mile, not far off 70 actual feet, to model the full working including the slip operation correctly and even a compromise solution would suggest at least a quarter of a mile. That's over 17 feet between the exit from the fy to the station, and while there are layouts around that can cope with this sort of space, there are not many of them. A railmotor or auto trailer is unsuitable for conversion to a slip coach, and while anything is possible if enough money or time is thrown at it, it would really be easier to stick to kits, scratchbuilding, or modifying RTR to make slip coaches. The Hornby Hawksworth Brake Composite is probably the most obvious RTR candidate, but is only suitable for the BR period. Prior to that you are looking for gangwayed Brake Composites, and the only other RTR is the Mainline/Replica/Bachmann 'Sunshine' BCK, and I am not sure that there were slip coach versions of these. Railmotors/auto trailers are not even remotely similar. They have severely bow ended bodies and underframes, whereas slips were flat ended, and the end windows are much bigger than those on slip coaches; the centre one on slip coaches has a droplight. An exception might be the 'Clifton Downs' flat ended compartment trailers, which were converted from Dean designed non-ganwayed cascaded ex-main line stock that might have had slip versions; you'd have to research it. Roxey do kits for this coach in auto trailer form; a slip version would have had smaller front windows but might be acceptable apart from that. 1 Link to post Share on other sites More sharing options...

bécasse Posted June 10, 2021 Share Posted June 10, 2021 And Worsley Works do actually have quite a good reputation providing that you accept that they sell "what it says on the tin", ie scratch-building aids and not complete kits. 1 Link to post Share on other sites More sharing options...
RMweb Gold The Johnster Posted June 10, 2021 RMweb Gold Share Posted June 10, 2021 Kits, unfortunately, are becoming a little problematic; actually they always were but are becoming more so. Most of the kit producers are one man band cottage industry operations and it is a part of the trade that is in serious decline as the owners retire or are withdrawn from service altogether and transferred to the Great Engine Shed In The Sky. Sometimes the ranges are taken on by others, but all too often these are also approaching retirement and the thing becomes too onerous to continue with. Comet (who don't AFAIK do a slip coach kit but have a good range of GWR coaches) are pretty solid and good value, but other manufacturers will need researching and it is not always easy to find up to date information about them. A possibly acceptable 'layout' slip coach could perhpas be cobbled up from a brake composite. There were single and double ended slips; for a single ended slip you need to remove the gangway connection at that end and cut the windows in. The central one has a droplight which I think was the means by which the slip guard attached a headlamp to his portion. 'SLIP' branding and an auto type gong below the windows, and a number of vacuum reservoir cylinders on the underframe (these are not the same as the operating cylinders, they are crossways mounted between the trusses) which enabled the guard to be able to release the vacuum brake after he'd already applied it for a controlled stop). A double ended slip, which can be slipped to another destination on it's return journey without needing to be turned, needs the treatment at both ends of the coach. TTBOMK there were no double ended Hawksworth slips and and I don't think there were any Colletts; you have to go back to Churchward toplight days, but I am happy to be proved wrong on this point. Ends were painted black, another difference from auto coaches. Link to post Share on other sites More sharing options...
Steamport Southport Posted June 11, 2021 Share Posted June 11, 2021 Comet slip? https://www.wizardmodels.ltd/shop/carriage/w46k/ I would go for that rather than the equivalent one in the Phoenix range. My view point of the BSL/Phoenix range is they are a bit dated and a lot of work. Too modern? Try the Roxey clerestory. https://www.roxeymouldings.co.uk/product/1044/4c56-gwr-f12-38ft-6in-slip-composite/ Jason 1 Link to post Share on other sites More sharing options...
Coach bogie Posted June 11, 2021 Share Posted June 11, 2021 I have built from several Worsley Etches and they are fine, especially considering the diagrams that only Worsley produce such as the C16 clerestory to go on the Hornby body. Decent thickness of sides as well. some kits are paper thin and distort easily. Here is what you get for the Worsley D42/H2 Dreadnought Tea car. No one else makes this. Worsley etched this up for me amongst others and it is now in his range. Clerestories have bespoke roof designs that slot and tab together with roof strips etched in- much improvement on the Mallard one size fits all roof sections.

Alan Gibson, Romford/Markits, some people even use the Hornby or Bachmann ones. ISTR that Larry Goddard (Coachman) had switched to the Hornby ones for some reason lost in the mists of time.
