Today we built the approach to the overpass coming from the Louisville side. I saw in a previous thread someone suggested cutting out the homasote to allow the grade to follow all the way to flush, and it worked great!
The gradient is variable all the way through. Starts at zero, gradually rises to just under 5 percent in the straight, then drops down to around 3 percent just prior to the curve. I kept the grade through the curve at around 3, then tapers off to zero at the bridge (haven't built the curve yet).
We set up the transformer and ran a few big locos up and down and it was smooth sailing.
