The first locomotive that Rogers' company assembled was actually built by Robert Stephenson and Company of England in 1835. This locomotive was the "McNeil" for the Paterson and Hudson River Railroad. It took another two years before Rogers received its first order for a complete locomotive. In 1837, the Mad River and Lake Erie Railroad ordered two locomotives from Rogers to form the beginning of the railroad's roster. The first of these two locomotives was the "Sandusky", which became the first locomotive to cross the Allegheny Mountains (albeit by canal boat and not by rail), and the first locomotive to operate in Ohio.
