I fully agree with this.

GP40X

OK if you like the flared radiators, but they are not spaced the same as those on the SD45, has two banks and not three.

GP40P

(passenger commuter loco ordered only by Central RR of NJ, with three later GP40P-2 ordered by SP).

However all these are really marginal locomotives, ordered for special needs - GP40X was a testbed for the new GP50, very few of them, and the commuter locos where really rare. Under 20 in the whole US.

I think the simplest adaptation may be to do the standard radiator section, cut out a couple of doors per side and do an SD40. There were hundreds of them and the frame length is the same as the SD45, so the powering options are probably the same.

Locos which are four axle and have the flared radiator.

Original owners, ATSF, UP, SP, SOU. Southern units came with a high short hood. SP and UP units had a very odd style of truck called the HT-B which I think was unique to them.

They seem to have worked for the later RRs like BNSF, NS and a few smaller ones, so if modern stuff is what you want, then I guess they are OK.


GP40P etc

A passenger commuter loco ordered only by Central RR of NJ, with three later GP40P-2 ordered by SP.

Interestingly the UP picked up the SP ones in the merger, and the CNJ ones still work today for NJ Transit so they are pretty high profile locomotives. Even I have ridden behind them. Indiana Harbor Belt has one too, for some reason.

The concept seems to have taken off with the rise of commuter RRs in the US and there are copycat versions like the GP40-2H. A commuter RR called Shore Line East has two painted in the old New Haven McGinnis livery.

However all these are really marginal locomotives, ordered for special needs - GP40X was a testbed for the new GP50, very few built, and the commuter locos are rare and generally only seen in passenger service, not a common thing in the US.

I think the simplest SD45 adaptation may be to do the standard radiator section, cut out a couple of doors per side and do an SD40. There were 1268 of them and the frame length is the same as the SD45, so the powering options are probably the same.
