in your opinions what will be the minimum height i need to reach to clear the crossover point

Ah, you just inspired me to find something I lost long ago.

BRMSB Standard dimensions. You'll find this useful for so many things you'll do on your model railway.

Kinda right.

It would be 3.5 / 60 = 0.058 = 5.8%

5.8% is 1:17 though. Because 100 / 5.8 = 17 (ish).

Thankyou, I'm much obliged. I never was very good at maths
