Is it possible to set the bend radius for obtuse crossings in a similar manner to setting the knuckle bend radius? The NERA booklet "Standard Railway Equipment - Permanent Way, 1926", suggests this is 16" multiplied by the crossing angle for angles between 1:4 and 1:8. It also seems to apply to the check rail as well. Thanks |

Hi Richard, The bend radius for K-crossings isn't currently supported. It's somewhere on my to-do list. Of course, now that the code is open-source, it can be on everyone else's to-do list too. It would be part of the journey over the years from Templot templates being simply construction aids, to being full descriptive drawings. Bear in mind that for wider than scale model flangeways, for good tracking through K-crossings the check rail bends need to be as sharp as possible, to maximize the checked length. This differs from the situation with the wing-rail knuckle bends in V-crossings. Fortunately, unlike the wing rails, REA check rails are always vertical, which makes it much easier to make sharp bends than in inclined rail. cheers, Martin. |

Thanks Martin With so much else going on here, I'm refraining from looking at the Templot codebase, however tempting the prospect is. |
