PA reengining

[garyla]

For a parallel in the automotive world, this is like taking one of those great-looking old Jaguars, removing the troublesome, expensive-to-maintain, long-stroke engine, and replacing it with a small-block Chevrolet V-8.

To some purists, it's a crime, but you get a beautiful machine that is now reliable.

I believe NYC also had on PB re-engined in their shops. It was not duplicated

D&H PA arrived on D&H with 16-244 engines. Re-engined by MK w/ 12-251's.

MKT, RI  & FRISCO FAs were done EMD.

MOPAC RS-11's were done EMD.

CR(PC) did a whole bunch of RS-3's with surplus 12-567s.  AMTK did a handful.

Isn't this one of the PAs that was sold to D&H?

In the late '50s, GE proposed a PA upgrade program that was adopted by both ATSF and SP. This program centered upon an upgrade/simplification of the controls.

Looks like the old SDG&E plant near the Santa Fe depot.

The AT&SF had their first PA re-engined with a 567, though it took a hit in power.

Dug around and was able to find this:

All three of 'em, wasn't it?  (51A-51B-51L)

1750hp doesn't look like 'that' much derating, but oh, brother, does it hurt at higher speed!

At least it wouldn't break cranks and all that...

Are you thinking of FAs?  I know of one NYC PB (booster) that was done at Collinwood in the late '50s.   'Christine' was the previous generation of Alco passenger power (DL-109, with the 'streetcar motors' that so mortified the Santa Fe people)

I seem to remember reading somewhere that some Alco PA's were reengined with EMD 567's any truth to this??
