This is my Narrow Gauge OO9 or HOn30 Brake Van. It is based on the Brake Vans seen on the Skarloey Railway in the Thomas & Friends television show. They are completely customizeable and for the details, see my youtube channel, Elsbridge Productions. This video on my Narrow Gauge Slate Trucks will give you all the details necessary as they share the same chassis as this Brake Van;

To have them ready to run, you'll need wheels, paint and couplings, all of which you can find cheap solutons for in the video above. Leave any questions anywhere you like and I'll answer them as best I can! Thanks, and happy shopping!
