Here's a curve for you guys to look into. I was recently told that with the ordering of the 800-900 series ES44AHs from GE, CSX has opted for standard applications of appliances. Most notably the High number boards, mounted over the windows in contrast to previous orders of GE models for CSX which were ordered with number boards mounted on the nose. This was suppose to be a cost cutting measure. I also understand that the "standard application" of appliances is the "standard" set by Union Pacific orders.
Harleys and EMDs, some of my favorite rides
