Here is my calculation

This can be also considered as simple derivation of Lorentz transformation up to the equation (i)

Now no worries to assign A and B to whether events or train ends as long as we are talking from the perspective of the train rest frame

the second image is more clear and accurate

Would you please do a little more work and type your calculations into a response instead of expecting all of us to scrutinize your attachments. It is very difficult to read what you have written and frankly, I'm not motivated. You also need to explain every detail of what you are doing. It might make sense in your mind, but remember, we can't read your mind.
