in einstein train thought experiment, if two bulbs were placed, in the front and rear of a moving train. And a person A with a single switch for the two bulbs stands in the middle of the train. Near the lights are clocks which register current time, when the light glows. would the person A see the lights simultaneously and the clock register same time? Also if instead of lights, two balls (speed < c) were released towards him, would those ball hit him simultaneously? Another person B outside the train in the ground, when the train has just passed him half of its length, if i'm right would notice the light/ball simultaneously from the front and rear of the train. How would he see the light and the ball hitting the person A?
