I guess some time management comes in handy, when summer and outdoor activities takes time from updating CZ-coaches. Some rain or mosquitos in the evening and I'm back fiddling with the interior. The rebuild of the interior in the observation lounge is coming to its end and is almost ready for paint.
The things I done to the observation area is filling in the holes from the old chairs. Made a new rounded floor end. Made holes instead of the slits in the original piece that was sawn off. The original stairs needed some attention. I cut off the sides on the two lower steps. Added trim and extended the lower step with two rounded pieces. I used Plasticard for all additions to the base, some laminated to get the right thickness. The only exception is the desk that was 3D printed. The glues I used was Tamiya plastic weld and some Gorilla glue, Cyanoacrylates.
Sanding and adding Tamiya's putty to level everything out, and sanding again. Below the stairs were a small recess that was filled too.
The pre 1960's observation lounge. Hopefully I'm getting there... 
The more fun part of the build. The 3D-printed chairs and couches is painted and I started to pick figures for the area. I guess I will go with this crew. Next step is to finish painting them. The standing lady is intended to be a "Zephyrette", on here way to attend to the old lady in the front. No CZ train is complete without at least one of the Zephyrettes.
Taking pictures of your build is a good thing to do now and then. A good way see more things that needs attention. The guy on the left in the gray pants looks like a more dubious german character from WW2. 
Adding figures to the upper observation area is a bit fiddly. Trimming down butts, spines and cutting legs. Some figures I filed down the sides to get two to fit the narrow couches. One way get more combinations of figures. Still some trimming and fitting to do in this area, before the finishing paint on the figures.
