This is a tinplate project I just started this summer (...to be continued until end of this year).
I didn't find any similar steam generator car or any heater car in the catalogs of the major O gauge or O scale manufacturers, but maybe I missed something.
Any way, after some investigation in historical archives I found various versions of steam generator cars and heater cars.
Some of their differences may be the following:
- with or without diaphragm
- with circular or rectangular window shape
- with or without side door
- side door at different location
- roof detailing with differently shaped exhaust pipes
- different truck type
Here are few photos of my on-going scratch-building project...
In this video you can see them in action...
In the published catalog (https://issuu.com/johannis_lik...neratorandheatercars) you may hopefully find the same car type model in the painting scheme of your favorite railroad. Lettering changes, re-numbering and re-painting is really easy. Critics and comments are mostly appreciated.
