The Lake Shore and Michigan Southern Railway, established in 1833 and sometimes referred to as the Lake Shore, was a major part of the New York Central Railroad's Water Level Route from Buffalo, New York, to Chicago, Illinois, primarily along the south shore of Lake Erie and across northern Indiana. The line's trackage is still used as a major rail transportation corridor and hosts Amtrak passenger trains, with the ownership in 1998 split at Cleveland between CSX to the east, and Norfolk Southern in the west.
The Baltimore and Philadelphia Railroad was a railroad line built by the Baltimore and Ohio Railroad (B&O) from Philadelphia, Pennsylvania, to Baltimore, Maryland. It was built in the 1880s after the B&O lost access to its previous route to Philadelphia, the Philadelphia, Wilmington and Baltimore Railroad (PW&B). The cost of building the new route, especially the Howard Street Tunnel on the connecting Baltimore Belt Line, led to the B&O's first bankruptcy. Today, the line is used by CSX Transportation for freight trains.
