... Again this applies just as much at the exit from the curve. Introducing even a short bit of transition curve between them can significantly reduce these effects. Q2) if there are two parallel tracks,...... how do you make the tracks the correct distance apart? Templot will do this for you, if you select the auto-adjust option when using the tools> make double-track function: 2_130832_030000001.png To save me typing it all out again, here are the more information notes for that: 2_130832_020000000.png Reading through that, I think the notes for manual adjustments need updating (what doesn't?).

For a crossover on a transition curve, the auto-adjust option is not available. It is better not to use the usual make crossover function. Instead make plain double track, and then insert a turnout in it. roam the turnout to the position where the turnout ...
