Track and wheel standard spread sheet
All are the same spread sheet with different input defaults. The dimensions calculated are the necessary dimensions for complex track work found in crossings.
On my H0 fine scale spread sheet I have default inputs for my recommended wheel dimensions.
The Proto 87 spread sheet has my recommended dimensions, which vary from the original and NMRA RP. The purists will not like this easy to make slightly coarser alternative which is 100% compatible with Proto 87 wheels. Track built to the dimensions I am suggesting will allow modellers to use re-gauged P4 wheels without reducing the flange thickness.
