Pennsylvania advertised itself as the standard railroad of the world and for years it was the nation’s largest railroad, especially in terms of locomotive and car ownership. The famous Pennsylvania four-track main line ran south from New York City to Philadelphia, then turned west across central Pennsylvania through the Alleghany Mountains via Horseshoe Curve on the way to Pittsburgh. The line continued across the farmlands of Ohio and Indiana to Chicago. Pennsy also had a line to St Louis. The Pennsy trailers are plain compared to the other trailers. One
is bright red and the other silver with just the Pennsy TrucTrain logo and Keystone herald.
