Apologies if this has been covered before. I was making a 1 in 12 crossover using the "Tools>make simple crossover" function with tracks at the usual 11ft 2inches centres. The result is something where you have to shove timbers and for this 1 in 12 I ended up with timbers going ABCDEDCBA from nose to nose where the ABCD refer to the usual chair nomenclature. Is this protypical to have a central timber? If so how are the rail joints arranged? By contrast 1 in 8 works out real neat ( ABCCBA ) with a gap in the centre where the two halves of the crossover can be fish-plated together. My question is : is my reasoning right or can somebody please explain prototype practice? Regards, Geoff |
