Without a diagram, I'm not entirely sure what you mean by A' and B'.

What I'm saying is, if the train is moving forward 40 mph, and you jump off of it sideways at e.g. 1 mph, then you are still moving forward 40 mph even when you're in the air. (Because when you're "connected" to the train, you're going forward at 40 mph. And that speed doesn't just disappear the moment you disconnect.)
So, relative to the train's new location, you'd land perpendicular. But the train has moved forward, so, relative to the ground, you don't land perpendicular from where you jumped off. (From a bird's eye view, you're moving on a diagonal. Mostly forward, but a little to the side.)

Will I be losing the train speed after the jump out from this train ?

I do not see the answer so I assume that I will be losing the train speed after the jump out from this train. Please refer (or someone else) to this (the second answer from the top)  https://www.quora.com/If-I-jump-inside-an-accelerating-train-will-I-land-at-a-spot-behind-where-I-jumped

"To take a wider view the ground accelerates the entire train, including the floor you were standing on.  As long as you were in contact with the floor, it can exert forces on you that accelerate you with the rest of the train.  The instant you lost contact with the floor, these forces vanish (all forces are local!).  In the absence of any horizontal force, your horizontal acceleration goes to zero, and the horizontal component of your velocity remains the same until you land on the floor behind where you jumped.  In the train frame of reference it would seem as if there was a force pushing you backwards, but there is no such force.  The train is moving faster than you in the other direction.

The idea of all forces being local seems to be contradicted by gravitational and electromagnetic forces, but no one has been able to really make sense of such forces without using the field concept.  Gravitational and electromagnetic fields are considered to be at least as real by physicists today as the ordinary objects all around us, and these fields act locally to produce forces."

Suppose you are on a bullet train going 150 mph.  You see a post ahead.  You jump from the train 1 foot ahead of the post.  You will slam into the post at 150 mph (less some wind resistance slow down, very minor) and turn into a pink mist.  I suggest you not try this experiment.

If one gets a running start in the train and jumps on a perp. plane out the door the momentum vacuum will lurch him parallel along train, only to be stopped by concrete post?

It is not about this whether I will slam into the post but "Will I be losing the train speed after the jump out from this train ?" because if I will be losing then this is the evidence that one of the walls would kill me and there is no so-called "earth's rotation" (look at my introducing commentary on this topic).

As james03 mentioned, you lose a minimal amount due to wind resistance, but this force is not enough to overcome the much greater force of the train's forward velocity. Newton's First Law of Motion says that an object continues to move at a constant velocity (or stays at rest) unless acted upon by a force. Wind resistance slows down your forward velocity, but only to a very small degree. Your forward motion in jumping off the train is stopped when you slam into the post. Otherwise, if there were no post, you jump and continue along the forward vector until you hit the ground, which ends the forward motion. If you jumped off the train the instant you passed the post, you would not land immediately behind the post, but further along from it, since you left the train with the train's forward velocity.

Maybe there is the rotation. Who knows...

And of course the Foucault Pendulum.

I thought there was a moratorium on discussion of geocentrism? Or does that not apply to the proposition that the earth is unmoving?

It isn't related unless one supposes so. The Earth doesn't have to be the center to be either non-rotating or non-revolving. It can be non-revolving but rotating, or rotating but non-revolving (around the sun). For discussion sake.

Momentum.
One of the scientists responsible for convincing others of the rotation of the earth was Jean Bernard Leon Foucault.  He introduced the Foucault pendulum as a tool to illustrate the rotation of he earth. BTW, Foucault died as a Catholic, so any claim that this experiment is related to Jewish culture is ridiculous.  BTW, is it true that there is a certain amount of anti-semitism on this site?

Long range artillery calculations have to account for the Earth's rotation. It does have an effect on the trajectory of objects in flight.

Next question.

Within Islam (among those of us who haven't been corrupted by the kufr thinking of the Mu'tazila; *cough* modern Asharis *cough*) it is considered a divinely revealed truth in the Qur'an that the Earth is immobile and orbited by the Sun. The Grand Mufti of Saudi Arabia, Abd al-Aziz Ibn Baz, famously defended this teaching publically in the 20th Century. Admittedly the about-face regarding this teaching in Catholicism is a stumbling block for me, but it doesn't seem that geocentrism was ever formally taught by the Papal Magisterium.

The Sagnac effect, the Foucault pendulum, the coriolis effect, the diurnal aberration all indicate that the earth is rotating. Further,  because the earth is rotating, the satellites are carried along with the earth's rotation, which allows them to maintain a stable orbit. If the earth were stationary, satellites would not be able to stay in orbit.
I don't see where this has anything to do specifically with Judaism.

I don't put much stock in the supposed findings of the "physical sciences" nor the philosophical presuppositions underlying them. I trust my own two eyes and divine revelation; with the latter having primacy over the former.

That said, I don't see how Judaism relates either. Historically the Jews interpreted the Geocentric passages of the Old Testament identically to the pre-18th/19th century Catholic Exegetes; and said exegesis was identical to the exegesis of similar passages in the Qur'an. It was a cosmology shared by all three religions. Plus, neither Copernicus nor Galileo nor Newton were Jews (though Newton was a hermetic).

Your own two eyes can observe the Foucault pendulum.
Further there are communications satellites which can be observed to be in geostationary orbits. If the earth is not rotating, why do you suppose that these geostationary communications satellites do not fall to earth under the force of gravity?
