Andy et all:

It's pure speculation on my part, and border-line counter intuitive, but one possibility is that the three demonstrators were 37' 1" and the production units 36' 9". Randy made a similar suggestion.
Again thanks to everyone for their ideas and assistance.

Hi Dave,

A drawing in the 1970 Car and Locomotive Cyclopedia gives 36'-9" as the bolster center measurment for the C-430. Of course by then it wasn't an Alco, but shown as an "MLW-Worthington" locomotive. Since no 430s were actually built after 1968 or in Canada, I take that drawing as representing the Alco specification.

So long,

Andy


 

Andy,

I have that Cyclopedia but that particular drawing is suspect in that it shows a fuel tank integral with the frame. Certainly none of the PC/Conrail C430 units I saw had such a frame. My understanding is that the only US domestic Alcos with that type of frame were the C-855 and the H-430.

That frame design was used on Australian built DL 500G units dating from 1970, and hence licensed from MLW and not Alco. These used MLW-Dofasco trucks as used on M and MX series units.

Of course, that doesn't mean that the dimensions are wrong, just that no units were built to that design.

The Tiger Valley C-430 measures 36' 9". I also have a Tyco shell (which is about a 1/4" longer than the TV shell). I scratch built the chassis in brass for the Tyco and comprimised with a 38' 6" spacing and a lengthening of the fuel tank by 1/8" to keep the proportions right, this is not noticable even with the two running together. Both have the TV Hi-Ad sideframes. Only a rivet counter armed with a scale rule would know the difference.

Pardon my fumblefingers, that should have read, "I found 36' 9"...."

Andy:

Ironically, the 37' 1" dimension comes from the September, 1986 MR, pages 78-79.  I found 37' 9" in the November, 1985 issue of "that other publication."

Everyone's assistance is greatly appreciated.  I hope I made it clear that this is a "curiosity question", as logically I'm going to match the Hobbytown underframe (with Tiger Valley hi-ad sideframes) to the Alco brass model.

 Two different drawings used as the source, one may have been a preliminary, or there may have been a design change mid-production.

Truck Centers Distance, Alco Century 430

(I submitted this once before but can't find that it was ever posted - if it's a duplicate and I'm just not looking in the right placeSleep my apologies.)

What was the truck centers dimension on an Alco Century 430?  I have found two different drawings in the model press; one says 36' 9" and one says 37' 1".  The Alco Models version measures 37' 0", close enough to the one drawing.  I also have a Tyco body mounted on a Hobbytown drive that's currently set at 39'; I'll be shortening that and my research as to what it ought to be is what uncovered this discrepancy.

Thanks in advance,

Dave
