I may have made light of this elsewhere. Penn Central was a combination of 2 bitter rivals, Pennsylvania RR (my grand dad worked for them) and New York Central. When the PC went bankrupt, it was the largest bankruptcy in the nations history up to that point. As a kid, I remember it being on the news quite a bit! I was born in the early 60's, grew up a couple miles from the PRR Mainline in Maryland, headed into DC. A good book to read, is called "The Wreck of the Penn Central".
