Problem

Design a scalable, fault-tolerant system that monitors railroad tracks in real time using a network of sensors (cameras, vibration sensors, temperature sensors) to collect data, detect incidents via ML models, alert personnel, and provide an operator dashboard.

Asked in the Service Design (New) stage. Cover real-time track monitoring with intermittent connectivity, low latency, and reliability. Explain how you would size the system, process sensor data, serve ML predictions, alert personnel, and operate the dashboard.
