That goes a long way in explaining why only one A/B/A set of ATSF PA's was repowered with 567 engines in the 1950's.

 

I believe so.

Even with the attractive prices GM was offering at that time to repower other makes as new unit sales declined in the wake of effective dieselization of America's railroads, Alco's deal had to of been significantly cheaper I'm sure.

And in addition to Overmod's excellent point about turbocharging and high altitudes, didn't those EMD repowers get derated to 1,750 hp? I suspect Santa Fe liked the added horsepower of these in the flatlands of Texas where much of their service went on, so I doubt they were thrilled with the derating of those three examples.

I'd love to know the reasons behind the selection of that particular set. Perhaps a reflection of their early nature and slightly different specifications? Or perhaps just as much a message to the bigwigs in Schenectady to see these famous locomotives being selected as their first choice to be repowered by the competition.

That set were celebrities of sorts as the first production examples of Alco's passenger line, were marketed as Alco's 75,000th locomotive, went on a national tour, were introduced at the Waldorf-Astoria Hotel's siding, etc.

Seems like a good way to voice your displeasure and get your point across to me.

Please tell me what these are.  My understanding was that the Cleveland 248 and 278 both had the camshafts right at the rockers, just to the inside of the V (unlike the 201A which had them in the block outside and just below the cylinder bores).

My apologies.

I was in fact thinking of the Soviet Kolomna 14D40, a V-16 used in the M62 locomotive, which was designed specifically to counter the EMD AA16 locomotive (built by Nohab and AFB) which ran as the M61 in Hungary. I don't know if any submarines used the D40 engine.

I think Kolomna is now in the Ukraine (maybe the Russian occupied part)..

The 14D40 is a two stroke with both a blower and turbocharger (like some of the bigger Detroit engines). It has some external  resemblance to the Cleveland engines but is quite different in construction.

The M62 was one of the most successful Soviet diesel locomotives and was used extensively in Russia although it was designed as an export unit for Eastern Europe with reduced clearances. It is very popular in North Korea.
