Yes, that is exactly what I have. My father was a car repairman on the NYCRR, PennCentral, Conrail RR by the time he retired. When repairing "hot boxes" he'd scrape out the burnt journal box packing and save the babbit that had melted and accumilated in the bottom of the journal box. Of course since all modern rolling stock has roller bearings, the source died out probably 20 to 25 years ago. The babbit was analyzed and has the same components and make-up as Rotometals #2 (Rotonickel-.15% Monel).
A side note, we (Dad and I) collected so much babbit in summer of 1964 when I went with him to work (because he was on the road and had broken his hand) that I was able to buy my first car from the proceeds of selling the high tin babbit as scrap for $0.33 a pound. The car cost a whopping $100! I'd guess Dad and I had smelted and sold at least 2000# of the stuff while I was in high school. Wish I had known then what I know now, I'd have a lot more in a stash.
