You have set up an impossible situation. The train observer cannot cause slit B to shut slightly after the light reaches A but before the light reaches B, because that would be faster than light.
That is only correct if the 2 events ( reaching A and shutting B) are time-like events. But Here they are space-like

Here is the set up of the experiment
