Junctionmad Posted May 15, 2018 Share Posted May 15, 2018 My club is building a derivative of badmington ( South Wales direct line ) in O Gauge, I’m not a GWR modeller so I was wondering how the platform side and corballing was executed . The station was predominantly red brick Any ideas or Pics ? Thanks Link to post Share on other sites More sharing options...
RMweb Gold unravelled Posted May 15, 2018 RMweb Gold Share Posted May 15, 2018 No details to hand, but I am sure I have seen pictures of replica platforms under construction on a preserver line, which showed details of the construction. E.g, http://broadwaystationgroup.blogspot.co.uk/2016/05/meeting-day.html hth Dave Link to post Share on other sites More sharing options...
Junctionmad Posted May 16, 2018 Author Share Posted May 16, 2018 Thanks , that looked like one row of corballing , I thought there was more usually ? Link to post Share on other sites More sharing options...
RMweb Gold unravelled Posted May 16, 2018 RMweb Gold Share Posted May 16, 2018 I'd agree that there are sometimes more, and I am sure I've seen a GW reconstruction, but I guess what was done changed over time. Increased clearances, as a refuge, were recommended at some point, and space might be needed for point rodding etc.. There's this thread from 2009 which might be relevant http://www.rmweb.co.uk/community/index.php?/topic/3196-gwr-platform-construction/ Thanks Dave Link to post Share on other sites More sharing options...

The Cheltenham reconstruction ultimately shows three rows of corballing , topped by 4x 3 flags and does seem to be an attempt to recreate the structure as accurately as possible with modern materials, and yes the modern " refuge " requirements do mean that the platform support was is set back a little more , so its remains to be seen Link to post Share on other sites More sharing options...
ejstubbs Posted May 16, 2018 Share Posted May 16, 2018 No details to hand, but I am sure I have seen pictures of replica platforms under construction on a preserver line, which showed details of the construction. E.g, http://broadwaystationgroup.blogspot.co.uk/2016/05/meeting-day.html Tenth photo down on that Broadway Station Rebuild page: "One or two trees at risk in secretive GWSR felling programme". It'll be on the front page of the local rag before you know it. (To the OP: It's "corbelling", BTW - https://en.oxforddictionaries.com/definition/corbel).

RMweb Gold The Stationmaster Posted May 20, 2018 RMweb Gold Share Posted May 20, 2018 Just remembered that I have some pics of the real thing, GWR fashion, ona platform which is probably not dissimilar in age from those on the Badminton Cut-Off. A click on the image will enlarge it to a more helpful (I hope) size. 1 Link to post Share on other sites More sharing options...
Junctionmad Posted May 20, 2018 Author Share Posted May 20, 2018 Thanks , yes thats very like Badmingtron , Is the top row bricks on their end ? Link to post Share on other sites More sharing options...
daifly Posted May 20, 2018 Share Posted May 20, 2018 Thanks , yes thats very like Badmingtron? Is that anywhere near Badminton? Dave Link to post Share on other sites More sharing options...
Junctionmad Posted May 21, 2018 Author Share Posted May 21, 2018 Is that anywhere near Badminton? Dave Can’t say , but from comparison pics , badmington had the same style of two step corbeling, with a bigger ( higher ) step near the platform coving Link to post Share on other sites More sharing options...
3 link Posted May 21, 2018 Share Posted May 21, 2018 Thanks , yes thats very like Badmingtron , Is the top row bricks on their end ? Most probably blue engineering bricks, they are a much stronger brick so less moisture can permeate and so last longer in use. These can usually be found being used as a top course on a lot of brick work. Martyn. Link to post Share on other sites More sharing options...
RMweb Gold The Stationmaster Posted May 21, 2018 RMweb Gold Share Posted May 21, 2018 Thanks , yes thats very like Badmingtron , Is the top row bricks on their end ? They look as if they are to me. I might be able to find a platform I can measure somewhere. (it's out of use before anybody asks and accessible by a public footpath). The dimensions for the slabs I have already posted on another thread. Link to post Share on other sites More sharing options...
bgman Posted May 21, 2018 Share Posted May 21, 2018 I'm not certain if these photographs are of any use ? Whilst waiting at Crediton Station earlier I thought about your question and decided to take these, amongst some other shots. The third photograph was taken deliberately to show the corbelling of the bricks where it has been altered and the original ramp moved slightly. There appears to be no blue engineering brickwork used at all, but then the station has been "upgraded" over the years so it would be difficult to tell from these photographs.

Ressaldar Posted May 22, 2018 Share Posted May 22, 2018 If you enlarge the view in the second picture in post #7 it shows that there is a mortar bed half way down the upper element which means that there are two course there - flush faced. To achieve the corbelling, the bricks must be laid as ‘headers’ otherwise there would be nothing bearing down on the course below and brought forward from the course below by less than half the length of the brick otherwise there would be no strength in the bond. This also means that the bricks laid behind the upper courses would also be headers to achieve the overall strength of the bond. Regards Mike Link to post Share on other sites More sharing options...
Junctionmad Posted May 23, 2018 Author Share Posted May 23, 2018 (edited) wow thanks folks , Im quite certain now Badminton was two rows of corbeling , with the top row as two brick depths appreciate all the effort ( and my spelling corrections ) dave Edited May 23, 2018 by Junctionmad Link to post Share on other sites More sharing options...
