Holmes Hinkley and his partner Daniel F. Child founded the Boston Machine Works and soon built the third stationary steam engine that was constructed in Massachusetts.
The company gained a reputation as a reliable and respectable locomotive builder and grew to become the largest manufacturer in New England within a decade.
In 1848 the company reorganized as the Boston Locomotive Works and operated under that name until foreclosure due to the financial panic in 1859.
In 1879, the Hinkley Locomotive Works built a 4-4-0 named "H. C. Hardon", and numbered 73, for the Atchison, Topeka and Santa Fe.
[citation needed] A Hinkley locomotive was used to transport Abraham Lincoln from Springfield, Illinois, to Washington D.C. for his inauguration.
