Nostalgia & History > gn sd9

I have 2 questions:     What type of horn did a great northern sd9 have?
Did the gn sd9 run long hood forward or short hood forward?

thanks. paul

GN first generation Geep's and SD's all ran long nose forward. Don't know about the horns.

Not sure if this helps much, these two SD9s, GN 573, and GN 587 each have a different horn type and mounting location. Slide date February 1970 by J.H. Lemke at Superior Wisconsin.

In that view, 573 has a Leslie Tyfon A-200-156 on the left facing us and a Leslie Supertyfon S-25 on the right facing away.  GN 587 appears to have a three chime Supertyfon of some sort (either an S-3L or an S-3K).  The Supertyfons are retrofits - new from EMD, the GN SD9's would have had pairs of A-200-156's.
