The shift from legacy systems to today’s enterprise mainframe reflects a broader digital transformation in railway management. Norfolk Southern has continuously invested in upgrading its infrastructure to meet the demands of a growing freight network.

Key Functions of the NS Mainframe

Train Movement Management

The mainframe tracks the real-time location of trains across the NS rail network. Dispatch teams use the system to schedule departures and arrivals, coordinate traffic across busy rail lines, and reduce delays.

This level of traffic coordination is essential when managing thousands of train movements per day. Even a small scheduling error can cause cascading delays across multiple rail corridors, directly affecting operational efficiency.

Cargo and Shipment Tracking

Every freight shipment that moves through Norfolk Southern’s network is logged and tracked through the mainframe. The system monitors cargo status from origin to destination, giving operations teams full supply chain visibility and transparency.

Accurate shipment tracking supports customer service as well. Shippers get reliable delivery windows and real-time updates on their logistics — reducing uncertainty across the entire delivery chain.

Crew Scheduling and Workforce Coordination

Crewcall is one of the most widely used operational tools within the NS Mainframe. It manages crew assignments, shift schedules, and employee availability across the entire rail network.

Employees can check upcoming work assignments and access their schedule through work schedule access — all through the mainframe interface. This supports broader workforce coordination and ensures that every train has a qualified crew ready at the right time and location.

Operational Communication Tools

The Memo system within the NS Mainframe delivers official company notices, operational updates, and safety instructions directly to employees as employee notifications.

This replaces slower communication channels and ensures that workforce-wide updates reach all relevant personnel quickly. Whether it is a route change, a safety protocol revision, or a scheduling update, the Memo system — along with other internal tools — keeps everyone informed through streamlined dispatching communication.
