Thinking about it, perhaps it should just be one setting instead of two.

I've changed engine reliability decay to stop once the no vehicles expire after year is reached

Well yes, they'll have their initial reliability values, not their maximum ones.

OK, I see what you are doing now. Probably best to combine the expiry/introduction stop year settings to avoid these issues with engine age and the reliability curves.

Unifying the settings doesn't seem necessary after all. Clamping the expiry to be not before the end of the engine's stage 1 duration should get the desired result.

It's the period of a year or so when the engine's reliability is rising to its maximum after the engine is first introduced, see here: https://wiki.openttd.org/en/Manual/Vehicles#maximum-reliability-ratings

That ought to be the case with the most recent commit
