I have been designing some mixed gauge pointwork and discarded all options as they are forced to include K crossings of angles around 1:10 ,where the gauge lines cross, because Martin's rules imply these cant be fixed Ks. However having examined his example BG crossover I find he happily includes such fine fixed Ks. Advice please! |

The opposite rail is fully checked, and it is therefore impossible for a wheel-set to take the wrong path through the fixed K-crossing. See the long check rails opposite the K-crossing: gwr_mixed_print_a1.png regards, Martin. |

Excellent, Thanks for speedy answer Now you have pointed out it is obvious really!
