Height for trestles, bridges, etc.

What is the recommended height for a bridge, trestle, etc? 1" ought to be enough, yes?

NMRA standard S-7 has clearance height of 1-8/32” (modern) above the rails for Z scale height and 1-6/32” for classic.

What is the difference between classic and modern?

I have newly made Marklin steam. Christmas engines.

The Classic era is from 1920-1969 and the Modern era is post-1983. Here is an index of NMRA standards.

On my old z scale layout, I was modeling modern CR/NS. I needed a 1.25" clearance. I could run most things. Autoracks and stacks would not fit but everything else I have would.
