Hello Martin You helped me a while ago in setting up the spec of Templot for LNWR timbering which I have now built the straight track with. Regarding turnouts, I have followed your postings about the importance of the "set" in the curved rail. I have the LNWR track drawings for 1909 and I can see no reference to a set though there are very detailed drawings of both straight cut and under-cut points. Am I therefore right in assuming that the LNWR may not have employed a set and used under-cuts instead where deemed necessary? Photos of LNWR track are hard to find but I have not seen any set in the few I looked at last night. I totally agree that the set would improve my running in P4 but I am just checking whether it would have been prototypical for my layout. Regards Peter |

Hi Peter, There is always a set or a joggle because without one it is impossible to set the track gauge correctly through the switch. The blade tips would have to be so thin and fragile that they wouldn't last 5 minutes in service. You never say never, but if LNWR switches didn't have a set I will eat a track template. An LNWR track drawing was posted recently on Templot Club, see: message 18021 Here is the full-size original uploaded: gallery/2110/original/2110_310840_390000000.jpg From which I have extracted this clip. I have drawn on the rail edges in yellow and blue, and you can see clearly that there is a set angle between them at the blade tip. 2_120837_340000000.png regards, Martin. |
