The mind boggles!! How many railroad companies ARE there in the US? The mind boggles! And if they're all now made up of mergers/acquisitions, then how many were there at the peak??? The ABC & D railroad through to the WXY & Z Railroad. Think I'll start up my own and just call it Alphabet Railways! BTW..... did the Atkinson Topeka & Santa Fe really exist? Or did the Andrews Sisters spend half their life changing trains??
