Reply to "Upgrading a 3rd Rail SD40-2 - Wisconsin & Southern"

Tim, yes we did. There are certainly different phases and features on SD40-2s since they were produced for like 17-18 years and close to 4000 units. Not sure if I have that correct, but I know it was a long time and a lot of units for the time.

Over those years I know the earlier units had more of a chicken wire radiator grill. open cage design which is closest to what 3rd rail did, IMO. While later units had the more corrugated style radiator grill with more depth and cooling efficiency.
