Many thanks to all of you who followed this project.
I will soon begin to work on making some Pullman Palace Plan 70 coaches for this Forney. Plan 70 was a design from 1879 for suburban service coaches and elevated railway cars. With bodies only 8' 9" wide, and 39' 4"long (not counting the end platforms), they seated 48. Thirty six identical windows gave them a 'rolling china cabinet' look of frailty.
But consider such cars never traveled more then 30-MPH between station less than mile apart. Further these cars built for Staten Island use did not carry car heating stoves or end platform steps.
First for a safety, the Gold steam heating system was used. Each car carried four 15" diameter radiator tubes under the length wise seating at the ends of the car. The tubes were filled with salt water, through which steam from the locomotive was piped via a train line. Once heated, the salt water radiator tubes could keep a car warm for up to 6 hours in winter.
No car steps meant that station platforms were all high level. This enabled faster boarding and alighting of passengers - especially for women given their mode of dress back then, traveling to work as typists and telephone switchboard operators as that new technology grew. Further, on Staten Island all stations were fitted with ramps to the platforms instead of steps where possible. Again for efficiency as well
Enough of this sales pitch! Here is a drawing for the Pullman Palace Plan 70 coach, as well as prototype photos.
