Hear the difference in sounds of GE and EMD locomotives dynamic brakes. Keystone, PA.

We are trackside at Keystone, Pa. as we watch two west bound trains drop down the western slope of Sand Patch grade. The are both passing under the old WM bridge, which is now a bike trail. The bridge was last used by CSX to pick up coal a few miles out just off the end of Salisbury viaduct. Here is a short clip of, what we believe to be the last train across the bridge,    • Last CSX train on Western Maryland's Keyst...   The fist train down grade is GE powered taken 7/07/1990, the second EMD taken 10/06/1990. They are both in dynamic braking at this point, and you can hear the difference in the two builders Dynamic brake features. The EMD may be a little harder to hear, as the friendly crew was saluting us as they passed. Also, at the time this was filmed, it was still three tracks on this part of the grade. The third track was taken out a few years later. 10/06/1990. Thanks for watching... All parts of this video and trademark are protected.
