Great work. Never thought of Plastruct for actual kitchen units as opposed to scratch building materials; see below.
That looks amazing! IIRC someone posted a thread on here with their detailed kitchen on their Polar Express diner a year or two ago. I don't have time to search for the thread now, though.
I think this is the thread you mean with a detailed account of Volphin's dining car rebuild:
Further back, there was this remarkable kitchen car super-detailing effort by Dreyfuss Hudson based on a GGD model, which is a bit of a head start over Lionel in the detail stakes:
My effort is not a kitchen car but the kitchen of a Lionel 21" aluminum diner, the Texas Special "Sam Houston" model, which is still a work in progress:
This is certainly not perfectly scale accurate (apart from the turkey!) but was planned on the basis of the standard Pullman-built diner kitchens of the time, including the huge range and grill unit, sinks and counter opposite and pantry on the side (adjoining the diner seating compartment) with everything in stainless steel:
I took a leaf out of other people's books and added lighting effects in the kitchen and the dining compartment; the "fire" under the grill flickers and can just be seen in the first and last photos. Here is the car as whole in a long view and the bottom photo is of the light show powered up:
