The "peak" is just a gap marking the end of the second 3% "step" upgrade. Past the gap the track progressively change to a 2% downgrade at the east end of Sullivan's Curve.
The problem was that 1/4 of the train was already on the downgrade and 3/4 still moving upgrade. Plus all the power on the head end.
I also eased the track superelevation of the gap curve. The name is "Rattler Gap".
