Just to be on the safe side, I decided to sit with my back facing the direction that the train was going. While I prefer to sit facing the direction I am traveling, you never know when an accident might happen. That way, if there was a head-on collision, I would not be flung across the aisle and get smashed into the front wall of the wagon. Hopefully the wagon would not be smashed like an accordion, and I would be able to escape by climbing out of the window.
