Pennsy re-engined a early RSD-7 that had the unreliable Alco 244 motor with an 567 emd motor. This brass motor in this model is a omi #3501.1 GP/SD35 567 2500hp motor, I think Pennsy used the non-turbo`d version but I wanted to try this for a repair scene at my engine house, it`s far from being complete

it looks like it should be sitting around a roundhouse or main shop awaiting final repairs

This project engine was sold in a box full of my stuff after a fire I had destroyed my home. Some stuff did get salvaged, and this project was salvaged, but the box of stuff it was in got sold for a hundred bucks. If anyone has seen or heard of this project please contact me here on Diesel Detailer. Thanks ... BRIAN CAMERON

It would be very unlikely that a non-turbocharged engine could obtain that horsepower rating... it simply could not be done but if it could have been EMD would have offered it. Turbocharging on a rebuild such as this nearly unheard of (lets not forget that ATSF did a similar repowering of most of its SD24s which resulted in a HP increase) since the whole point is to save money when dealing with this unit.
Does anyone know the number for this unit? Would be interesting to see if photos could somehow be tracked down of the prototype...

It was in the back pages of the first or second Jerry Pinkepank's Diesel Spotters Guide that this info was obtained from, and was stated the rebuild program was brought about to try to salvage the RSD7's with the troublesome unreliable Alco 244

Is the repower project in question actually the Penn Central 9949? It was an ex PRR 8611 RSD-15 that PC repowered with a 1200 hp EMD 567B. Paired with a RSD5 slug that shared the same number and was assigned to the hump at DeWitt yard. The combo later became CR 6849. Another set was planned but cancelled.
The repower had the external appearance of the RSD-15 changing by two exhaust openings instead of 1 turbo exhaust and two large EMD type radiator fans replacing the single Alco fan. The slug kept it's cab with its side windows blanked out until it was eventually removed and various pieces of an RS1 or Alco switcher hood replacing it. Work was done at Syracuse in 1975. Resulting model was called AEH-12

All,
The ALCO in the photo looks more like a EX- PRR ALCO RS27 than a RSD?

Actually I believe the loco in the picture is a C420.

Actually I believe the loco in the picture is a C420. Actually the engine in the photo is an RSD15. It appears some alco info is needed to supply some info on models of the alco line of locomotives for some to feast they're eyes on so they'll be able to make a call on the great alco line that so many of us long after ... just sayin

I was referring to the photo that is attached as your signature. Which is an ALCO C420 as it has two axle AAR trucks which makes it the four axle loco shown. The C420 was the only Century series loco to have the long short hood like the RSD15. The RSD15 would have 3 axle Tri-mount trucks making it a 6 axle loco.
If there is a different picture showing the engine of the rebuild you ask about it is not showing in any message I have read.
