I am revisiting my Terminus design to try to get the trackwork to 'flow' more smoothly. On the prototype, when a crossing of say 1:8.2 was encountered, did they build it to this angle or use the nearest 'standard' of 1:8 or 1:8.5 and realign the surrounding track? Cheers, Brian |

Brian According to British Railway Track Design, Construction and Maintenance 1956 reprint the crossing angles to be found in standard leads is as follows:- ex GWR 1 in 8, 8.25 or 8.5, ex LMS, LNER and SR 8 or 9. These crossings being manufactured from bull head rail. In flat bottom work the choice is between 8 and 8.5. In all likelyhood these ex company standards were adhered to after nationalisation. It would be my assumption that Pway designers would have been encouraged to use standard crossing angles and amending the plain line to suit.

Thanks Rob. I didn't know if each instance was a bespoke design and build or whether they had a stock of common components. You have answered the question! Cheers, Brian |
