Sorry for the delay. I didn't have all the numbers, so I had to wait for an email reply from a club member who had the information.
Maximum grade on the mainline is 2.38%.
Minimum radius on the mainline is 48 inches.
Minimum on branch lines is 36 inches.
Frogs are mostly No. 9 on the mainline and minimum No. 7 elsewhere (turnouts are hand laid in place).
Rail is Code 83 on the mainline, mostly Code 70 in yards and on spurs and branch lines.
I hope this answers your questions.
