Stanley No. 1
The Stanley Works rostered a 45-ton 0-4-0F (fireless) steam locomotive, the Stanley S1.
HK Porter no. 7230 built in September, 1936.
Cylinders - 22" Diameter, 18" Stroke
Drivers - 36"
Wheelbase - 6' 3"
Length (over bumpers) - 23' 0"
Height - 12' 8"
Weight - 90,000
Advised radius of operation - 60 feet
Sharpest radius of operation - 35 feet
That works out to ~5" or ~8" in HO(!) unless my math is wrong...
They are rated to haul 1,420 tons on level track, the equivalent of twenty-eight 50-ton cars. Even as much as 170 tons up a 3% grade.
It was sold (donated?) to the Connecticut Trolley Museum at Warehouse Point c1970.

A fireless steam locomotive has no firebox or smokebox. Instead of burning coal or wood to heat the water in the boiler and generate steam, the locomotive is connected to a steam line at the factory. Only a 5th of the tank is filled with steam, the rest is water. Each charge can run for two to five hours. Recharging takes about 15 minutes.
The Connecticut Trolley Museum sold the locomotive to Railstar who, to the best of my knowledge, intended to put it back in service. On July 2, 2005 a 12- and two 13-year old girls started a fire that burned the warehouse where it was being stored. The locomotive was damaged significantly and moved outside where it has remained.
Here's a series of photos I took while taking measurements in July 2020.
Note the dent in the top of the back of the cab was there when the locomotive was at the CT Trolley Museum.
A sketch I made using the measurements I took.
The drivers show the 36" of the prototype vs 50" drivers on the Mantua 0-4-0 "Shifter" that I might use as a chassis.
