QUOTE: Originally posted by M636C Matt, How about we try to clear most of these up at once. The description GP 40X was used twice, for the prototype locomotives that were used to develop the GP40 and later for the prototypes of the GP50. Since both of these were used to develop successful models, the actual sales are irrelevant. Some features of the second GP40X, in particular the low weight transfer truck, were not used on later models. We can conclude that they weren't worth the extra cost or were not enough of an improvement on the standard truck. It is almost impossible to conceive of a 4200 HP SD40. That is a 40% increase in power over standard. The SD45X, a 20 cylinder locomotive was rated at 4200 HP. These were only prototypes, but may have contributed to the eventual development of the SD80, the next 20 cylinder locomotive from EMD. Dash 3 is used to indicate an older type of locomotive rebuilt with microprocessor control. Two types of SDP 45 were built. There were passenger service versions built for Southern Pacific and , I think Great Northern (GN also had SDP40s). Erie Lackawanna bought a number of "SDP45s" which had no steam generators, but used the longer frame to allow a larger fuel tank. I would be surprised if any remained, although some might have been rebuilt as SD40 locomotives. Less than twenty passenger service versions were built, and the FP45 effectively replaced the SDP45 for passenger service. Peter

Peter On another note how many freight locos(ALCO, GE, EMD,etc.) were offered with a passenger option? I checked, and as far as I can tell, SP had ten SDP45s, GN had eight SDP45s but the "Freight Only" versions with EL numbered over thirty. Still no idea about survivors, if any. Peter

QUOTE: Originally posted by M636C QUOTE: Originally posted by Sterling1 On another note how many freight locos(ALCO, GE, EMD,etc.) were offered with a passenger option? All six axle U-boats were available with a steam generator, but only the AT&SF U28CG units were actually built. The AT&SF U30CG are basically the same but fitted with a cowl body. No Alco Century units were built with passenger equipment apart from the C420s built for Long Island where the steam generator was placed in the (high) short hood but presumably the option was available on other units. Some Mexican GP38s were built with high short hoods with steam generators, and there have been a few SDP35, SDP40 and SDP45 units built. There have been GP40P units with rear mounted steam generators, but survivors have been fitted with HEP gear instead. Many GP40s have been rebuilt with HEP gear for commuter service. SP had a number of GP9s and SD9s in commuter service out of San Francisco, as well as the SDP45s (post Amtrak) and the only GP40P-2s built. The passenger option with high hood units was fairly common, but SP's were amongst the last in service (until Caltrans took over with F40PH units).
