The Pennsylvania Bway Limited sound car is not the dining car rather it is the kitchen car. The Bway Limited was one of the onlytrains that had a separate kitchen car. If you examine the dining car which comes with the kitchen car as a two car set you will see it has a full length interior since there is no sound equipment in it. The kitchen car does need to be opened up in so that some sort of opaque barrier can be put in the four windows that cover the sound equipment area. At the same or a latter time it is also possible to model an actual kitchen scene that could be seen through the four windows at the opposite end of the car. I am planning to do this. I can not under stand why Lionel did not have the factory not put frosted windows at the sound equipment end of the car but this is not a deal breaker for me.
