Just booked a roomette on 1/SL and was assigned roomette 18 in car 0131. After having consulted Superliner car diagrams and consist listings for the SL it appears that this reservation will be in the transdorm sleeper. Some previous posts had mentioned that the transdorm sleeper cars have the shower on the same level as the roomettes. if that is correct then it would be very convenient when time comes to freshen up. Are there any disadvantages that i should be aware of being in the transform sleeper? The SL consist shows this car as being directly behind the baggage car at the head of the train.Would that have any effect on the ride quality? Welcome any and all comments on this.
