Norfolk Southern runs one of North America’s largest freight networks.
Its shipping clerks managed order processing on a mainframe that demanded hundreds of memorized command codes.
The job wasn’t to reskin it. It was to answer a harder question: can you modernize a system that can’t go down, for people who already know it cold?
The green screen worked if you’d put in the years: dense fields with no hierarchy, ASCII navigation, function keys worn into muscle memory. It was fast in expert hands and merciless to everyone else, and the learning curve kept the knowledge locked in a handful of veterans.
Supervisors and executives needed something the terminal never gave them: a live read on order health, exceptions, and trends, not a report assembled by hand after the shift. Clerks needed the same speed without the memorized codes, and both had to live in one system.
The legacy
Green screens
Command-line terminals and function-key navigation: the operational backbone of a major railway, built for another era of computing.
Cryptic codes · months of training · no live oversight
The mandate
One modern system
Speed up order processing for clerks and give supervisors and executives a live operational view, from the same product, not a second reporting stack.
