preliminary engineering

Phase 1 (15% Design) of preliminary engineering is now complete and the Refined Route of the King of Prussia Rail Project (KOP Rail) was released. The Refined Route was improved from the recommended Locally Preferred Alternative (LPA) with the North/South design option.

The design refinements included:

  • Detailed engineering analysis of the rail alignment and guideway design
  • Minor modifications to station locations and designs
  • Initial assessments of potential property and environmental impacts
  • Studies of rail operations, and other details

These design refinements were the direct result of community input, comments at the public hearings and other stakeholder meetings, coordination with affected property owners, engineering criteria, and continued review of the existing land use and future development opportunities. These designs are still preliminary and are not ready for construction.

Phase 1 was integral to the successful completion of the Final Environmental Impact Statement (FEIS) and combined Record of Decision (ROD) from the Federal Transit Administration (FTA). The FEIS, signed in January 2021, identifies environmental and community impacts and commits to specific mitigation and minimization actions to eliminate or reduce negative effects. The ROD is the official decision document of the Federal Transit Administration (FTA) for KOP Rail to continue into further engineering and construction of the project.

After the FEIS/ROD phase, Phase 2 of preliminary engineering will build on the efforts of Phase 1 and will add more detail during 30% design. Phase 2 will also include FTA requirements for project development, such as a project management plan, cost estimate, and project delivery schedule.
