Can anyone direct me to some information on the differences between these engines? I can spot most differences between the 424/425 variations but, am not too sure on the 430’s. I have tried to look at photos but, am unable to find good straight on comparison shots.

My library has two handy-dandy Kalmbach Diesel Spotter’s Guides, and; they are well worth the effort to secure them with a ton of stats & spotting tips in addition to pictures. Double-check to be sure that the diesel years you need to be covered are in the guide(s) you are considering to purchase.
North East Rails is a neat source of prototype pictures…

Two easy ways to tell a 424-425 from a 430:\
Air intake aftercoolers “buldge” (just aft of the cab) is much larger on the 430 than on the 424-425. Also, most of the 430s had the Alco Hi-Ad truck, which looks nothing like the AAR type B under the 424-425.
The 430 is also longer.
Another is a noticable buldge in the radiator section on the 430.
Now that The Second Diesel Spotters Guide is handy, on pages 252-253, we find…
C-424 => 192 units made 4/63-5/67. Smaller main generator due to 2,400 Hp. 16-cylinder motor. Car body filters are missing due to adoption of the sealed car-body principal. There is a lack of a bulge in the radiator.
C-425 => 91 units made 10/64-12/66. Larger main generator due to 2,500 Hp. 16-cylinder motor, and; is the same as used in the GE U25B due to Erie Lackawana’s insistance. The only other external distinction of the C-425 compared to the C-424 is a broadening of the hood in the radiator area. Car body filters are missing due to adoption of the sealed car-body principal.
C-430 => 16 units made 7/66-2/68. A 3,000 Hp. 16-cylinder motor, and; the after-cooler assembly is bunched up behind the cab. The last ten units built went to the New York Central with Hi-Ad trucks.
Note the (1963) C-424 had the older-style rearend while the (1964) C-424 & C-425 reverted to the notches.
P.S.: Good insight from “my neighbor” - Shanksville’s tsgtbob.
You’d probably get a better response over at the Trains forum.
thanks for the info guys. I was wondering if the car bodies were similar between the 424/5 and the 430’s. I wanted to do one up in the Western New York & Pennsylvania colors to go with the 424 that I have. Looks like it will have to be a kitbash/scratch build.

Also the cabs are different. The C424/425 had the “v” front cab shared with the C420 & C628. The C430 had the cab where the areas over the walkways are 90 degrees to the centerline and only the area over the nose is “v” shaped. The cab used on the C430 is also used on the C630 & C636.
Yeah, I didn’t have my copy of TSDSG handy or the story of the C-430 that was in Diesel Era on my desk either.
What, screwing off while at work? NOOOO! NOT ME![:-^]
tgindy, if you have visited the Laurel Highlands Model RR club in Somerset, the O scale layout is mine…
