In N scale, what is my minimum clearance for passing under a bridge? Is 2 inches enough? Not enough?
I’m doing this for memory, but I think that most rolling stock clears 1 7/8" in N. I just round up to 2.
skiloff,
Check the NMRA web site: http://www.nmra.org . They have all this kind of info on their “Standards and Recommended Practices” page. Here’s the direct link to the page: http://www.nmra.org/standards/consist.html#standards

NMRA says 1 21/32"
Or doing it the prototype way, you need at least 23 ft of clearance (really 22 and change, so I rounded up).
Divide 23 by 160 (N scale) to give you .14375 ft. Multiply that by 12 and get 1.725 inches.
For you people without digital calipers, thats 1 23/32".
A calculator is your friend.

I stand corrected.
So thats roughly 4 1/4 centemeters?
1.725 in x 2.54 cm/in = 4.38 cm or 44 mm.

Thanks guys. I knew I could count on quick responses.
