Pilot for the Class I Dispatch Modernization


As part of a project enhancing a 37k-mile rail network with PTC, our globally-known rail client required a highly skillful contractor to perform PTC upgrades for its centralized dispatching system. Before starting such a large-scale project, we negotiated a trial to confirm skill compliance and define the optimal engagement process. Deadlines were essential to meet the mandated government requirements for the national-scale PTC introduction.


Client Challenge

Estimate PSA skills and interaction capabilities to launch a national-scale PTC introduction product for the Class I railroad.

Project Objective

Deliver a pilot to showcase PTC-compliant development for the centralized dispatching system, as well as a flexible engagement process.


First, the PSA team defined the process for effective engagement on the dispatching product modernization. This included error resolution, adding new features, and creating new subsystems. We suggested and established:

  • Documentation and coding standards research

  • Documenting of code and design & code reviews

  • Domain knowledge training for engineers

  • Definition of process control tools

  • Data exchange options – online transfer, scrum meetings & weekly status reporting

  • Issue resolution flow – prioritization, resource estimation, assignment, and process tracking

  • Risk identification and management

Second, we resolved a critical issue to showcase the capabilities of its modernization. Our team had been traveling onsite to study the system, its communication standards, and technical PTC requirements. To troubleshoot the product, we researched and reproduced the issues, then fixed and debugged it while maintaining a transparent resolution process. 

Third, PSA prepared a fixed-price proposal for the modernization of the security component comprising multiple upgrades for the whole system. 

As a result, the client commended the PSA development and communication capabilities, and wished to proceed with further activities. This pilot project introduced a new chapter of safety on this Class I railroad.
