Six-wheeled F class goods locomotive for the Indian State Railways. Date uncertain, perhaps around 1901. Related text in the original publication is not decipherable from the scan, but there is mention of flanges and other metalwork being done at Ajmer and the results being cheaper, at a quarter of the price for similar metal-working in England. The F class 0-6-0 was the most numerous built metre gauge locomotive in the 19th century (perhaps of all time too!). From "Railway and locomotive engineering : a practical journal of railway motive power and rolling stock" (1900s) Scan from the Internet Archive of Book Images.
