The Vandalia Railroad was formed in 1905 as a collection of a number of railroads between St Louis & Indianapolis. In 1921, part became known as the Pennsylvania RR.
Most of the line was abandoned in 1976 by Penn Central and in 1982 by Conrail. Some portions of the western half continued into the 90's. The Pennsy / Vandalia corridor is still largely intact with a few scattered incursions.
