Benn Posted October 26, 2015 Share Posted October 26, 2015 Afternoon all,I'm after some dimensions and a decent picture or two of the 3 piece type concrete grids that sit in the 6 foot, made up of two slabs of concrete with a grid in the middle. Usually found where the drainage is a bit poor, for example in a cutting or through a station from what I can gather. A couple of pictures here of what I'm after, seen between the running lines, just to clarify; https://www.flickr.com/photos/10113772@N00/4364476711/in/gallery-55746092@N00-72157630764984168/ https://www.flickr.com/photos/bristolsteam/6012337086/in/gallery-55746092@N00-72157630764984168/ I'd like to scratch build some to put on my layout, so any help would be most appreciated.Thanks,Benn.

RMweb Premium Grovenor Posted October 26, 2015 RMweb Premium Share Posted October 26, 2015 You should be able to work out the size pretty well as the concrete cable trough units are 1 metre long. Rgds Link to post Share on other sites More sharing options...
Benn Posted October 26, 2015 Author Share Posted October 26, 2015 Thank you very much gents, that's fantastic, just over 1.5ft per section them I'm going to guess, and approx 3ft wide. I plan to cut some rectangles to the correct size, and score some lines in the middle for the grid section. It's N gauge, so I think I'll get away with that... It's things like this that make this forum excellent, the most mundane and non interesting question is answered within a few hours, telling me exactly what I need to know! Makes up for all the nonsense that has to be trawled through on occasion. Link to post Share on other sites More sharing options...
RMweb Gold TheSignalEngineer Posted October 27, 2015 RMweb Gold Share Posted October 27, 2015 A fairly recent drawing. http://www.ihsti.com/NoRCS/docs/brafas01/dept/elec%20pub/network_rail/nr_completed/CIVILS/CIVSD351.pdf This is a concrete catch pit ring. Although apparently approved by NR, it does not seem to meet the requirements if human access is required. https://andertonconcrete.azurewebsites.net/DocumentControl/documents/rail_techincal/matisa_catchpit_frame.pdf Link to post Share on other sites More sharing options...
