the brandywine valley's main line was originally built by the wilmington and northern railroad, largely following the brandywine creek, to connect reading with wilmington, delaware. by the time of the brandywine valley's formation, the line had been abandoned north of valley station, just north of coatesville. bvry took over the line from this point, the site of an interchange with amtrak's keystone corridor, south to modena, below which the ex-w&n was owned by penndot and operated by a number of shortlines over the years.
