The cars aren’t available, but if you are looking for inspirations, the SPCRR at Ardenwood have two tiny narrow gauge passenger cars: SP 1010 has a 28’ body, while Arcata and Mad River 2 is only 25’ long.
1010 is a combine (built as a coach) with an arch roof. She is restored and in occasional use on our railroad.
Car 2 is our latest acquisition, a gift of Henry Sorensen and his children. It was built as a coach, with a bull nose clearstory roof, converted to a caboose complete with a cupola, but was reduced to a body sitting on a standard gauge flat when the railroad standard gauged. Henry has it back on narrow gauge trucks, with platforms and couplers, but much work is still needed.
Both cars had stoves, and longitudinal seating.
