God you're acting the clown. You have very little understanding of relativity, as you've shown already, but you keep trying to pretend. Why don't you actually say something, instead of bullshitting?
Answer, because as soon as you do, you get it wrong.
Such as :

Acceleration is change in velocity over time.
As velocity has both magnitude and direction, in the case of rotation around the centre of the Milky way, it's the change of direction that's relevant, not the speed at any instant.
Good point.
I've already answered your dumb question, when I posted about general relativity and the curvature of space time being responsible for the "apparent" acceleration towards the centre of the Milky Way. You obviously didn't read it, or didn't understand it.
You went on to waffle :

But still, both station and train are accelerating. Is the effect of acceleration/gravity linearly related to its effect on the Special Relativity equations? What I mean by that is, is the fact that it's only a small amount of acceleration/gravity mean that it only introduces a small variance into the Special Relativity equations?
You only need to know a tiny basic bit to know the answer :

But they are not in an inertial frame, because they are accelerating. SR deals with inertial frames. MM has yet to tell us the effect that acceleration has on SR calculations, other than to offer speculation.
This is absolute bollocks. Everything is in an inertial frame. You can of course accelerate in an inertial frame.
Why the fuck do you blog on when you don't know what you are talking about?
The point about general relativity is that it's a model that handles gravity and accelerating frames more easily.

Special relativity, contrary to some outdated descriptions, is capable of handling accelerations as well as accelerated frames of reference.[8][9]
I've made the point in different ways that the curvature of space time in our location due to the Milky Way is negligible. That's perfectly relevant, as stated above.
It's not negligible, if you are talking about timeframes of 250 million years, again as I pointed out.
If you had had the slightest clue what you were talking about, you would have understood all that.
As it is, your input is a waste of space. Literally.
