When you have government representatives that don't understand technology, it doesn't get funded.

It's no wonder everything is emulated/old/never-replaced.

In defense of government, they need to have an audit trail and (in functioning democracies) can be held accountable when things go seriously wrong, so it means they only have a select few orgs to choose from that have passed all the certifications/due diligence. Connex (the company running the show at the time) were a private operator who has lease of the rail system for probably long enough to justify modernizing some of the systems, but maybe not enough to justify a full rewrite. Rewrites of systems with big safety implications, like civil transport, would have a different risk profile to upgrades of less consequential legacy systems

Edit: Apparently it did eventually get replaced https://news.ycombinator.com/item?id=29158255
