Inspired by a photo in Garden Rail magazine, and by this car at Clark’s Trading Post:

I’ve whipped together a pair of light passenger cars for the railway.
The basis is the Hartland Locomotive Works ore tipper.
I kept the frames but discarded the tipper and replaced it with bench seats. A set of small Bachmann steel wheels and wooden dumb buffers complete the transformation to narrow gauge. Red paint with black trim makes it fit in with the passenger fleet. Now I need a set of 1:20.3 passengers to hang on for dear life.
They debuted on the RR at the Fall Steamup in October:
I need to get some properly-sized passengers, but otherwise I’m happy with them. The look good with Konrad and his IP Engineering coaches.
