Career

Early years

He was apprenticed to a shipbuilder and later worked for Robert Stephenson, the Grand Junction Railway and the Paris and Rouen Railway.[2]

Chief mechanical engineer

He was Chief Mechanical Engineer of the Caledonian Railway (CR) from 1847–1856, the Eastern Counties Railway (ECR) from 1856–1862 and, following a merger of railways, of the Great Eastern Railway (GER) from 1862–1865.[3]

Consulting engineer

Sinclair resigned from the GER 1865, and became a consulting engineer. In this capacity, he designed a fast 2-4-2 locomotive for the Great Luxemburg Railway, and an outside cylinder 2-4-0 for the East Indian Railway. The Luxembourg 2-4-2 design was later adapted into a 2-4-2T for commuter services on the GER.[4]
