I have been trying to design a 60' track jig so I need to know the distance between the sleepers so I can make some spacers, I have been sent this guide to help but is it correct? Len |

It shows the spacings for traditional jointed track with timber sleepers for the BR post-nationalization era. The table shows centre-to-centre dimensions, so to create spacers for a jig you need to subtract 10" (the width of a sleeper) from each dimension. Modern concrete-sleepered CWR (long-welded) track differs. Pre-nationalization track also differs for each company and period, although not by much. Pre-grouping track for different companies varies more and generally used shorter rails. Those dimensions for 60ft bullhead rails are the default settings in Templot2, so to create a jig for such bullhead track you can simply print some straight plain track templates. To choose between 24, 25 or 26 sleepers per length, go to the real > plain track options > rail lengths and sleeper spacings... menu item. For flat-bottom track you will need to enter the table dimensions as custom settings. regards, Martin. |
