Some Interesting Facts from
The Great Railroad Strike in Ohio
The Doubleheader
One of the most dangerous things crews face on a freight and coal trains was the doubleheader. This was the doubling of cars engines run with the same number of crewmen. Regular freight and coal trains on the Pennsylvania Railroad, for example, consisted of one engine and eighteen cars, so a doubleheader had thirty-six cars with an engine on either end. This and a wage cut motivated workers on the Pennsylvania subsidy Pittsburgh, Fort Wayne & Chicago to strike on July 19, 1877. This fact came from The Great Railroad Strike in Ohio by this website's creator, Mark Strecker. You can buy it at Amazon or from the History Press.
