If, your travel takes you to the area there are many Historic sites that you MUST SEE, including
The Baltimore & Ohio Railroad Musem, Carrollton Viaduct, Thomas Viaduct are all located within thirteen mile radius of the Center City.  

There is plenty of railroad activity. The yards, port area and the NE corridor are all in close proximity  
In addition, AMTRAK, CSX and MARC lines radiate in all directions. Some areas are more secure than others so you should be aware of your surroundings.

The Carrollton Viaduct, is located in Carollton Park and is easily accssable, via a paved bike path fooling the stream and a foot bridge. The Park has plenty of parking and appears to be a secure area although Ho-Bo's have set up a small camp under the I-95 overpass on the far side of the stream. 

The Viaduct is tucked between an industrial park, scrap metal yard and Carrollton golf Cuorse.  A visit to the Viaduct does require some walking. The Park is adjacent to the I-95 ramp for convienent access.
