IF those are Lionel Die cast Sprung trucks , those trucks are certainly not "Cheapo" . They were PREMO trucks of the Day from the 80's to the mid 1990's. From your third Picture:
One can see the raised base of the underside to prevent the truck from riding and eventually catching and scratching the body side sills.
I say this is a custom boxcar. Blank cars sold by Lionel and decorated somewere else or a promo.
IT would not be the OLD Atlas 1970's becasue of the raised Floor adapted for that die cast truck.
