The rolling suitcase that I normally travel with is 14 inches wide, stands 23 inches tall, and is 7 inches thick. If I had two of those bags, I could just barely fit both of them side by side in the cubbyhole above the hall. The same sized bag can also fit underneath your seats. One bag could be a little wider than mine by maybe an inch or two, the other I’d say could be approximately 5 or 6 inches wider. They could not be much taller or thicker and still fit underneath the seats. There is also room for a shoulder bag next to the larger of the two seats. Your car attendant will try to accommodate larger bags, but it is very difficult for him to do so. He usually has to store them in the shower room, and in the vestibule of the car. This means that he has to keep moving them around as people enter and exit the train at stations, or if someone wants to take a shower.
