I just received a flier from TMW for their new American Steel Foundries A-3 70 Ton trucks. Brian does a super job on his trucks and he always list the railroads that used the trucks. He includes SP and Santa FE for this truck, however, when checking Tony's SP books and Richard's SF offerings I cannot find cars that I have modeled that used this truck. Can anyone specify just which cars used this truck on the SP and SF?
