Another name that railroad is the Jersey Central. Here's the cover of his rules book that shows a crease where he used to fold it to carry in his pocket.
Having suffered such a horrendous accident PopPop was always one to stress safety to his grandchildren.
I looked at the exam card below and wondered why it was so neat and unsigned. It wasn't until I scanned it that I noticed the typo in the name, spelling "Estilow" as "Eastlow." Most likely they typed out a correctly spelled one which he signed and carried. Perhaps they let him have this rather than throw it away.
