Jun 1, 2022 at 13:56 comment added Marius Ladegård Meyer What they will agree on, is the value of $c^2 (t_A - t_B)^2 - (x_A - x_B)^2$ (with or without primes).
Jun 1, 2022 at 13:55 comment added Marius Ladegård Meyer The observers in the train will have two space-time coordinates for the event "the light reaches person A", $(t_A, x_A)$, and similarly for B, $(t_B, x_B)$. In their frame of reference, $t_A - t_B = 0$. The person not in the train will have different coordinates for these events, and both the time and space coordinates will be different. For them, $t_A' - t_B' \neq 0$. Both have correct descriptions of what happened in their respective reference frames.
