This is the first time I've seen this in a car interior. Toilets and sinks. At both ends of the car. Busy reinstalling the glazing in my Q dome car project and noticed these for the first time. Who ever designed the interior for Concor went all the way on these. Now have to check the diner to see if it is as detailed. Will there be plates on the tables? I've only detailed the interior on two cars some years back, one a log camp car where I do have plates on the table and clothes drying on a line inside along with bedrolls on the bunks and the other is Loius Hill's private car with a auto in the rear garage area of the car, but this does raise the bar a bit. Hmm a little fella using the facilty?
