Scaffolding and netting were erected around the station last year to protect pedestrians from loose stonework on the station's facade.
Some exterior pre-restoration work will get done under a contract now out for bid, but the station's full restoration must wait for congressional funding.
Meanwhile, Amtrak is creating a new master plan for developing the station and its environs that likely will include proposals for building over the sprawling Penn Coach Yards that stretch north of the station.
Amtrak is working with Drexel University and Brandywine Realty Trust to redevelop the station and its University City neighborhood, and proposals are expected to be unveiled within two months, Galloway said.
"We are looking for smart, tasteful development of the area," he said.
The plan will also propose better access for buses, cars, bicyclists and pedestrians.
The station, Amtrak's third-busiest, was opened in 1933 by the Pennsylvania Railroad. It handles 120 Amtrak trains, 400 SEPTA trains, and 26 NJ Transit trains each weekday, and more than eight million passengers used the station last year.
But the station is isolated by a river, two expressways, a cordon of busy streets, a wasteland of parking lots, and the train yards.
Galloway spoke at a day-long conference on rail transportation hosted by the Rail Users' Network and the SEPTA Citizens Advisory Committee.
