During the first engineers school in June I experienced the hill 'the opposite way'. I brought the train down the hill from Lava with 487. As we swung around the curve and apparently 'started our descent' I saw what was coming and added something more than a 5lb set to the brakes. Couldn't figure out why we nearly came to a stop. Marvin was looking over my shoulder and just smiled. Definitely an optical illusion.
