This idea adds a connection on a grade (blue) to replace the steel bridge reverse connection which allows the out and back from the yard route, then heading back into the yard. This connection is at a 4% grade, at the limit of acceptability, but the good news is that the grade can be taken DOWNHILL to complete the out and back route.
The revised steel bridge connecting the turn-back curves is now optional, not needed for the out and back route. But it allows trains to reverse direction the other way. So with this option, the layout now has reverse connections in both directions, to turn trains.
The max grade in the turn-back loops is 2.6%.
