A question about Norfolk Southern's SD40-2 fleet.
In viewing the excellent NSDash9.com http://www.nsdash9.com/roster.html" onclick="window.open(this.href);return false; website NS has apx 500 SD40-2 in its fleet. I was wondering what does NS use all these units for. I know NS is a very large railroad and the obvious answer is to move freight, but with all the newer units (SD60, SD70, SD75, SD80, SD90, Dash8-40, Dash9-44, ES44AC) along with the GP and MP units they also have, what role do these seemingly ageless units preform?
