6959 Posted September 20, 2013 Share Posted September 20, 2013 I am working on the two versions of the prototype CK coach S15000 and have managed to 'cut and shut' Tri-ang sides to work out the cut lines before risking cutting a Bachmann model. For the body I have used a broadside photo of each side of the coach with ACE headboards, and interior shots plus the Diagram 126 sketches in Parkin page 93. Looking at various photo's, the buffers on S15000 differ from those used on the usual BR MK1 coaches, and the under frame bits look different and more Southern than BR. Where can I find information or pictures showing the correct under frame details of S15000? Before and after pictures of the corridor side. Original (maroon) Tri-ang CK side and cut and shut S15000 side still in blue. The two types of interior with later all-compartment version at top. The original open end in the incomplete lower picture will probably come out of a Bachmann RFO. Thanks in advance. Link to post Share on other sites More sharing options...
mark54 Posted September 21, 2013 Share Posted September 21, 2013 If you haven't noticed them, there are 2 underframe photos in Parkin that are reckoned to be S15000 because of the reversed angle trussing (i.e. flat side outwards). That might be tricky to replicate! Mark Link to post Share on other sites More sharing options...
6959 Posted September 21, 2013 Author Share Posted September 21, 2013 When I cut up a Tri-ang/ Hornby MK1 coach side, after the glue has set to touch dry but is still soft, I put the sides in a coach to ensure the sides are straight before the joins set hard. Corridor side of S15000 in Tri-ang chassis and roof to check alignment. Compartment side of S15000 in Tri-ang chassis and roof to check alignment. Mock up of Tri-ang side in Hachette underframe. The bottom tongue on a Tri-ang/ Hornby MK1 is 1,6mm (1/16th inch) but the tongue on the Hachette and Bachmann coaches is 1mm thick. It is easy to file down the Tri-ang side to fit the Kader chassis (Hachette/ Bachmann). Also, the Tri-ang side needs to be notched at each end to clear the moulded butresses on the inside of the Kader ends. The top is more tricky and the Tri-ang side needs to have a flange glued along the top inside to fix the roof. Mockup of Tri-ang side in Bachmann underframe. Each type of Bachmann underframe has fouling lugs moulded into the slots to suit a particular coach side so notches need to be filed on and foreign side lower edge to clear these projections. My models of S15000 will most probably be assembled into Hachette donor coaches. My modified CK sides came out about 1mm too long which suits the Hachette base. The 1951 demonstrator version with semi-open design will be glossy crimson and cream. The full corrider 1952 version will be toned down to make set Set 531 comprising BSK 34653 - CK 15000 - BSK 34654 which ran on the Ilfracombe section of the Atlantic Coast Express. Modeller's licence will be applied to fit the period 1951 thro' 1957-ish when S15000 was repainted green. Link to post Share on other sites More sharing options...
tabalf Posted November 13, 2013 Share Posted November 13, 2013 You could have saved yourself a lot of work by using the Kitmaster CK which has the dimensions of prototype S15000. You would still have to amend the underframe of course.. Link to post Share on other sites More sharing options...

mark54 Posted November 13, 2013 Share Posted November 13, 2013 The Kitmaster CK although purporting to be a standard Mk1 design has both it's 1st & 2nd class compartments of differing widths for some strange reason. They do not correlate to S15000. Mark Link to post Share on other sites More sharing options...
tabalf Posted March 26, 2014 Share Posted March 26, 2014 Thge Kitmaster coach is correct in having different sizes for the compartments. This can be seen in the prototype as illustrated above. The Ian Allan ABC of BR coaches mentions that S15000 has firsts 2 @ 6'73/4", 2 @ 7'25/8" seconds 2 @ 6'27/8", 1 @ 7'2". Where the Kitmaster is incorrect is that the windows and doors on the corridor side are based on the production coaches rather than the prototype. I had not realised this when I wrote the earlier piece. Link to post Share on other sites More sharing options...
pete_mcfarlane Posted March 26, 2014 Share Posted March 26, 2014 The list of Mike King drawings I was looking at the other day includes one for S15000, so that's another source of information. Link to post Share on other sites More sharing options...

I had not realised this when I wrote the earlier piece. But the wrong compartments have the wider spacing. On the Kitmaster coach the two wider 1st class compartments are adjacent to the centre vestibule, not the ones adjacent to the toilet as on S15000. Likewise the wider 2nd class Kitmaster compartment is adjacent to the toilet and not to the centre vestibule as on S15000. Link to post Share on other sites More sharing options...
