In the case of twin A on board of train moving at v relative to platform where twin B stands, when they reunit (disregard acceleration )which will be the case:
1- a & b look the same age
2- A sees B older
3- B sees A older
4- Both A & B see each other older
A brief expl. is also welcome

(In the case of twin A on board of train moving at v relative to platform where twin B stands, when they reunit [sic] (disregard acceleration )which will be the case:)
1- a & b look the same age
2- A sees B older
3- B sees A older
4- Both A & B see each other older

4- Both A & B see each other older
When they reunit[e] time will have passed, therefor, they will both see each other as older because, they will be older.

Exactly right, Anomalous!

Einstein's absurdity , in my very humble opinion, is in making the measurement of "time" an axis in some sort of coordinate system which defies logic.

When the image of the hands of a clock, or even the digits of a digital clock, leave the clock in the form of a wave front, neither the hands nor the digits change within the image, as the image travels the distance from the clock to the observer.

Both the clock's hands or digits keep changing, as well, so does the observer's clock; indicating a new present moment, sending additional images.

Changing the distance between clock and observer merely changes the duration of the time the image spends in transit. The duration of the transit of the image is the entire object and subject of relativity. The rest is conjured out of whole cloth.

You can't disregard acceleration.

While the train is moving, A is aging more slowly relative to B. But if you want them to meet up and compare notes before and after the train ride, you must accept the General Theory as part of the result. Otherwise, you're just going to get silly answers.

Your answer is proof of that contention Anon.

To which acceleration is Anonymous referring? Gravity? the acceleration caused by being in orbit around the Sun? The acceleration caused by being on the surface of the Earth as it rotates diurnally?

The time problems were caused by Einstein's misunderstanding of relativity in his Special Theory of Relativity. When it became evident that there weren't any, the problem was supposedly move to to his General theory. By the denial of a universal time, and placing "time" on a fourth "axis" perpendicular to the three in Cartesian space, one can manufacture all kinds of anomalous fictions.

The truth is that relativity is simply about the finite speed of a light pulse over a given distance.
