.... READ WITH INTEREST THAT TRUCKS DESIGNED FOR SOLID BEARING
JOURNALS CONVERTED TO ROLLER BEARING JOURNALS WERE OUTLAWED IN INTERCHANGE SERVICE IN 1994. ANY INSIGHT INTO WHY THIS TYPE OF TRUCK/BEARING ARRANGEMENT WOULD BE OUTLAWED, AND WHY SO CLOSE TO THE OUTLAW DATE OF THE SOLID BEARING EQUIPPED TRUCKS?
No, I can't account for it. But maybe Chris Barkan can; IIRC, he was working for the AAR at the time.
