Armstrong (of Punjab)
From Graces Guide
'Sometime in 1868, Mr. Armstrong, of Rawilpindee, Punjab, India, made a neat little steam car riage, having two steam cylinders, each 3in. diameter, and 6in. stroke. A trunk was used, so as to do away with slide bars. A separate stop valve was fitted to each cylinder. The boiler was 15in. diameter, 3ft. high, and was worked at loolb. steam pressure per square inch. The carriage travelled at twelve miles an hour on the level road, and up an incline of one in twenty at the rate of six miles an hour. The driving wheels were 3ft. diameter. The engine had been running more than a year when the above particulars were forwarded by Mr. Armstrong to The Engineer' [1]
