Although some railroads have a highly integrated, single-vendor system for their train control and operations functions, most train control and operations centers must make do with a set of disparate legacy information technology (IT) systems. This article discusses some general principles that may be helpful in streamlining these operational systems. Most railroads are highly computerized, but the IT systems could be considered "islands of information." Effective IT solutions can break down the functional silos that develop in most companies and support the service delivery cycle as a whole, without compromising the integrity of the real-time safety-critical control systems. The key is a service-oriented IT architecture where functional modules are able to communicate via interfaces. Interfaces must develop between long- and short-term planning, short-term planning and day of operations, and performance monitoring and planning functions. These interfaces can help boost productivity and reduce costs by improving the flow of information through the operational business cycle.
