... enough to match the track standard, as in 4-SF (00-SF). The widest gap in a crossing, across just in front of the nose of the vee, is the same in a 1:50 crossing as in a 1:5 crossing, or any angle. The longest conventional turnout which can be created using the pre-sets in Templot is 1:80, for which you need the 30ft straight switch. It looks like this, its 1700mm long (5ft-6in): 2_311950_190000000.png The 1:80 V-crossing: 2_311950_190000001.png For which the vee nose would need to be filed much sharper than most switch blades.

There's some pretty long switches at Ashford on the HS1 line set out for 300km/h running. I was half-tempted to make a 1:50 to see what it would look like ...
