    Didn't ConCor sell the C-636's back in the 70s? Would those have them? (granted, they would probably have pizza cutter flanges, but the sideframes might be usable)

    NJ you are right on the money. I have one of those and it does have the high adhesion truck. Obviously the cant be swapped out. And the axle spacing is different. On the standard truck the three axles are spaced differently where as the the high adhesion truck axles are spaced the same. I wonder if a six axle sd50 or 60 axle would fit in the C630? Could swap out and sand down the side frames and glue the old ConCor frames on. I wonder.....

    "Didn't ConCor sell the C-636's back in the 70s? Would those have them?"

    One of the problems in trying to use the Concor truck sideframes is that the truck itself was too short. There is some info on building the correct length of truck over on the N-scale Kitbashing list from the Concor truck, which is worth taking a look at!!! Its in, I think, the Photos section which likely will require a person to join if they are not already a member (don't get me started on Yahoo! Groups) but it is some really good info...

    Briggs Models ( http://www.briggsmodels.com ) offers a Dofasco Truck kit for the ALCo and this is a symmetrical truck and together with parts of the old ConCor/Roco trucks it should be possible to build something...

    ...the ones on the yahoo group are built based on a Kato SD40 truck and parts from the ConCor/Roco model.

    (yes, close up pictures are brutal - something is missing)

    the kits are complete new trucks including the gear housing, all you need from the original Atlas trucks are the gears and the wheels...

    Dofasco trucks were used in Canada and possibly on some Mexican M-series locomotives as well. They were used because of their shorter wheel base.

    Hi
    The easiest way to make an acceptable Hi-Ad is to use an existing Flexicoil truck with some of the details filed down then add the centre part of the Con-Cor frame. See below:

    I'm sure some of you have seen this before, but for those who may be new, here is the finished item.
