Alaska Railroad obtained a fleet of Alco RSD1 units after WWII. Some of these were bashed by the ARR into the 1070 class RF1 covered wagons for passenger service. Several were converted to 4 wheel AAR road trucks. Others survived until retirement in the late 1960s in their original design. Alaska Railroad Number 1029 was in service until 1965 so here is my version of and RSD1 Alco in Alaskan service. alaskarails.org/creations/PD-RSD1/index.htmlPat Durand |

There was a thread a while ago about doing the trucks on these locomotives, I remember posting some of my pictures of the one in the RR Museum of PA. Did you make the truck sideframes yourself? How did you do it?

Rudy,
The RSD1 trucks on Alaska 1029 are what I call good enough. Most photos will never give you enough detail to figure out all the equalizers, springs and brake rigging. I have obtained highly detailed photos from Michael Patrick taken when the ex Alaska unit was moved from Strausburg to Ft Eustice. If you give me a mailing address I'll send you a cd with all the source photos and build photos for the model.
In short: The RSD4/5 trucks have the correct wheel base but roller bearing journals. I used a sharp knife and shaved off the bearing caps, actually saving all 12 for another project. Features that did not comport to the desired side frame were lobbed off.
I shaped a piece of styrene square stock to the end profile of the journal boxes and then cut them off one at a time. Each journal box cover is four pieces of .010 and .005 styrene built up. I used MEK to assemble the styrene parts and then applied them to the side frames using IC 2000 (black tire glue). I also used repeated applications of the IC 2000 and accelerator to "weld" fill the profile at the ends of each side frame. This material will cure and become part of the side frame ready to be filed and sanded to shape.
I made slivers of styrene to simulate leaf springs. I shaved coil spring detail from some throw away trucks. The brake cylinders are Precision Scale plastic part #31096. All of the other brackets, brake hangers and levers are styrene flat stock whacked up on my trusty Chopper II. When I painted it all black and then dusted it with white chalk, it looked like the casual photographs, "good enough".
Good enough, meets my goal of an artistic rendition of the prototype on an excellent mechanical assembly that I can operate for years.
Glad you liked the result so far.
