So since our backyard has a long long slope (approx. 35’-40’) going to the west from our layout I am wanting to build a trestle bridge and am wondering should I be concerned about running a trestle this long?
The elevation drops from 1’(@current track location) to 4’ at the end of the yard, then goes up hill to the south about 5’ in a span of about 16’-18’ I know this incline is way more than 3 degrees so I would have to do something to make the climb whether it be in a “S” configuration or something else. But for now before I get too into build a ton of trestles I am just wondering about the overall length. Any input is appreciated.
