Looking for 70t trucks from Atlas Hart ballast hoppers

[bbussey]

Folks,

I am looking for sets of 70-ton trucks (National C-1) from the Atlas Hart ballast hoppers.  If anyone has changed their cars over to MTL trucks, still has the original trucks on hand and is willing to part with them, please let me know.  Thanks.

NOPE those are not the ones he is after those are roller bearing trucks not friction bearing they only put these on the Hart ballast.I have called Atlas quite a few times hoping that they will offer these separetly but as of a few months ago they still were not and no one else has a 70 ton friction bearing truck available.
Ask any SPF guys and they now of this delema if they are building an NSK kit.

These are 77T National C1 trucks right? I'll add these to the Atlas list.

Just National C1... truck capacity is determined by bearing size, wheel diameter and axle spacing.  Since AAR standards have changed over the years, if your going to rate them by capacity, then also need to factor in the years in which they would be applicable.

I think I have some black and brown trucks on the way.  I can still use two pair of the oxide red (such as on the Soo Line car above) to put on a pair of Alan Curtis (now N Scale Kits) F30A flatcars.  I'll use brown if I have to, but would prefer the oxide.

Still waiting for their Andrews trucks to be available separately.

Didn't realize the Andrews weren't available either.  They are interesting in that the bolster cross beam is far lower than all other Atlas and MTL trucks, which is most of the reason why the three USRA-type boxcar models sit at scale height above the rails.  I suspect that they wouldn't work on MTL equipment.  They would save the need to lower the bolster itself, but the surrounding area on the underframe would have to be removed to allow for wheel clearance and proper coupler height.
