we have only trained in late oct, and nov. since we were hauling luggage, we booked green car(there is a bit of space at the end of the car for luggage). the non reserved cars looked packed. during each trip, it appeared that all seats were taken at one time or another(8 trains total) most passengers seems to be male business me. they all had expensive suits. if you are going to train, i recommend one buys a beneto box at the station before training.
