Pittsburgh is intervening to challenge Norfolk Southern’s plans to alter three North Side bridges to establish a second route for double-stacked rail cars.
The city Thursday morning released copies of a letter and a protest it filed with the state Public Utility Commission this week. The commission is reviewing railroad plans to two raise bridges and lower another to create room for double-stacked cars to operate on the North Side route and supplement the existing route through the South Side.
