Wait, you’re suggesting replacing trains because the computers inside them are old?

I think they're just saying parts should be periodically replaced across the board on that timeframe, and using the fact that the trains are being swapped out as an example. The Breda trains are still running some percentage of the fleet however. I rode in one today.

That’s right. System refreshes are a fact of life, especially if one is parsimonious in using what works until obsolescence. There are downsides of doing things that way, but I don’t see it inherently more defective than other approaches, such as some kind of continuous refresh that has a conceit of keeping a system “modern” in perpetuity.

But twenty years for a train seems very low. My daily driver is 12 years old, I thrash it every morning and never gives me problems. I live in the snowbelt.

By comparison a train is vastly over-engineered and has an electric drive train. Sure stuff will need replacing but a train should last 40 years at least
