Suppose you had access to all your country's data including all data stored at all companies, how would you use this data to improve the railway network?

Objective:
- improving punctuality

Example:
Asking automotive companies for their labelled image data.
They already use it to train their own ML algorithms.
So the railwork companies could use the same data to train automatic driving models and to spot e.g. persons on the tracks or other barriers blocking the path
