Realism vs not; how they work is how they work. I agree, this is the way they've always behaved and changing that carries some risk. It's ultimately up to taste, but IMHO the acceleration around top speed just "feels off" and this is what I found when I looked into it. In lieu, is there a...

A log: https://pastebin.com/9dmBKmSH The Problem Air resistance should be proportional to velocity squared, but it is currently only proportional to velocity. Symptoms In vanilla, trains accelerate more than they should at high speeds and don't accelerate as much as they should at low speeds. With t...
