Your human edge
The main tasks with no real AI use seen and no big speed-up expected. This is where your skill counts most today.
- Signal locomotive engineers to start or stop trains when coupling or uncoupling cars, using hand signals, lanterns, or radio communication.
- Observe train signals along routes and verify their meanings for engineers.
- Inspect couplings, air hoses, journal boxes, and handbrakes to ensure that they are securely fastened and functioning properly.
