摘要：	The purpose of this study is to identify the feasibility and cost benefit for obtaining two (2) track double stack vertical clearance along the Keystone Corridor from west Philadelphia to central Harrisburg. The Pennsylvania Public Utility Commission (PUC), which has jurisdiction over all rail/highway crossings in Pennsylvania, requires that new bridges be constructed such that the minimum vertical clearance between top of highest rail and overhead bridge structure is 22.0 inches. These clearances are in accordance with the PUC, Chapter 33-Railroad Transportation, Subchapter C-Clearances adopted in March 1978. The PUC requires a vertical clearance of 24 feet-3 feet electrified rail territory, which is the case for the Keystone Corridor. Norfolk Southern, the exclusive freight carrier with trackage rights on the Keystone Corridor, currently operates double stack trains between the Harrisburg and Philadelphia markets via Reading. This route is approaching operational capacity, in order to provide additional capacity between the Harrisburg and Philadelphia markets, the Keystone Corridor is being evaluated for double stack clearances. The following objectives have been accomplished: (1) Identify the double stack clearance restrictions along the Keystone Corridor; (2) Identify the possible engineering solutions to obtain double stack clearance; and (3) Identify the costs and benefits for the Commonwealth of Pennsylvania of obtaining the double stack clearances. / NOTE: Final rept.
