Ian_B Posted June 15, 2022 Share Posted June 15, 2022 several years ago one of the Modelling magazines (Model Rail I think) printed a clearances diagram which showed the clearance in MM from the rail to surrounding objects (Platform edges, bridge abutments, signal masts and heads, catenary etc etc. Does anyone, by any chance have a copy?

ejstubbs Posted June 15, 2022 Share Posted June 15, 2022 I don't know if it's the one you have in mind, but this is the one I usually refer to: No idea where I first got it from, I'm afraid. 2 1 2 Link to post Share on other sites More sharing options...

It's from a Railway Modeller publication - it's something that has appeared multiple times. In 'Starting in scale OO', for sure. 2 Link to post Share on other sites More sharing options...

Philou Posted June 16, 2022 Share Posted June 16, 2022 (edited) Would this table be helpful too? I can't locate the drawing that accompanied it at the mo'. It showed most of what is on the dimensioned drawing above but also showed from where the radii were taken when constructing tunnel mouths. If I can find it again, I'll post it separately. Cheers, Philip PS: The .gif isn't a moving picture, just a picture. Edited June 16, 2022 by Philou 3 Link to post Share on other sites More sharing options...
Philou Posted June 16, 2022 Share Posted June 16, 2022 (edited) Aha!! Found the drawing! Cheers, Philip Edited June 16, 2022 by Philou Forgot to attach the drawing!! Doh!! 3 Link to post Share on other sites More sharing options...
Philou Posted June 16, 2022 Share Posted June 16, 2022 Maybe you'd like this one as well - very clearly laid out. A more modern version of the first drawing. I use a centre spacing of 45mm and not 50mm as shown as dimension A in this latest table as I find it more realistic though you have allow for 'widening' on curves of less than 7ft (c. 2.1m) radius due to under- and over-hang.

No doubt it has been published many times, but the specific OO one posted by EJStubbs earlier, is exactly the same as the one in my book, except there is a box at the top which says 'appendix 1'.

Its useful because it combines all the major scales. 1 Link to post Share on other sites More sharing options...

This any good? https://www.elginmodelrailwayclub.co.uk/2010/articles/advice/standard-railway-modelling-dimmensions.html "The following diagrams show the structure dimensions with the table indicating the appropriate measurements in various scales as devised by the British Railway Modeling Standards Bureau (BRMSB)." It's not the BRMSB web site as mentioned by Les Bird - but then I'm not sure that such a thing exists, given that the BRMSB itself seems to have ceased to operate 60 years ago or more, before the world-wide web was even a twinkle in Tim Berners-Lee's eye. There's another thread about the BRMSB standards here. 1 Link to post Share on other sites More sharing options...
Philou Posted June 20, 2022 Share Posted June 20, 2022 .............. and just when you all thought it was safe to come out, here's another one. This time, it's for comparative purposes as it's for the 1:1 railway - extract from the Blue Book. You can compare the real world dimensions with our modelling ones.
