Description
Hitachi installed cameras on trains to capture video of 40,000 km of overhead rail lines and built an AI pipeline on Databricks Lakehouse, using Delta Lake for storage and MLflow for model management, to analyze the footage and alert rail network operators to defects or displacement in near real-time, enabling predictive rather than reactive maintenance.
…. Now the company was generating a huge volume of video data from their trains, capturing images from a total of 40,000 km of overhead lines — the distance equal to one lap around the world! — that they’d have to analyze…

Problem
Monitoring and tracking potential overhead-line issues was traditionally a manual task: network operators walked the tracks, visually inspected lines from moving trains, or relied on infrequent measurement trains limited to detecting certain issue types. Any overhead line break caused delays and costly unplanned disruptions.
…ructure running smoothly is a costly and labor-intensive endeavor. In the past, network operators would have to manually maintain infrastructure by walking the tracks to inspect overhead lines on foot, monitoring it from the window of a moving train to visually inspect potential…
Solution
Hitachi installed cameras on trains and uploaded the video to the cloud, building an end-to-end AI pipeline on Databricks Lakehouse. It uses Delta Lake for data storage and pipelines, MLflow for model management, training, deployment and experiment tracking, and Databricks SQL for monitoring dashboards, analyzing footage from 40,000 km of overhead lines to generate near-real-time alerts on defects or displacement.
