I recongize those demos they are SD45X's or at one time SD55's. these were 4200 hp using a twenty cylinder 645 just like the SD45's but rated higher. SP got these for about twenty years before they were return to EMD. Only one is known to exist today as a test engine.

What a great photo, even the new SD-45s are not in front of the coolest locomotive ever made, the GP-30!
