Railway engineer After marrying in 1872 (see notes below on his family), Ross became chief engineer of the
Wisconsin Central Railway and then the
Lake Ontario Shore Railroad. On Lake Ontario, Ross came into contact with
George Laidlaw and several other well-connected railway promoters, who persuaded him to come to Canada. He was appointed chief engineer of Laidlaw's
Victoria Railway, and in 1879, he built the
Credit Valley Railway. Ross was then appointed as acting consulting engineer for the
Ontario and Quebec Railway, during which time he came into contact with three ambitious young men, namely
William Mackenzie,
Donald Mann and
Herbert S. Holt. After slow progress was being made in connecting the
Canadian Pacific Railway west of
Winnipeg, in 1883 under new CEO
William Cornelius Van Horne, the company formed the wholly owned North American Railway Contracting Company (NARCC). With the brief to meet up with the team driving east from the Pacific Ocean under
Andrew Onderdonk, Ross was appointed general manager and chief engineer of the NARCC, and he immediately employed the services of Mackenzie, Mann, and Holt. Starting at
Swift Current, they built of railway to
Craigellachie, British Columbia, by 7 November 1885, over the
Rocky Mountains, At the time of his death, he was still a director of the CPR and was said to have been the company's largest
shareholder. • Ross as general manager, • Mann preparing and grading roadbeds, • Mackenzie cutting the ties and organising timber work for trestles and bridges, and • Holt laying track, general finishing, and clean-up work. Advising on and constructing feeder lines north from the CPR mainline, the company completed early work on the
Winnipeg and Hudson Bay Railway, and constructed both the
Regina and Long Lake Railway and the
Calgary and Edmonton Railway. The partners also negotiated the incorporation of several land development companies, including the
Calgary and Edmonton Land Company and the
Canada Land and Investment Company. In a later 1887 partnership with
George Stephen, 1st Baron Mount Stephen and Van Horne, they established the
Lake of the Woods Milling Company, which bought and processed grain. In 1889, Ross became first president of the
Columbia River Lumber Company, which provided timber for railways and housing projects.
Street cars and electricity After moving to
Montreal in 1888, in partnership with William Mackenzie, he oversaw the electrification of
street railways in Montreal,
Saint John, the
Toronto Street Railway and
Winnipeg Transit. They later took over the
City of Birmingham Tramways Company Ltd in England, reorganising and electrifying that. Mackenzie then looked for other opportunities in South America, resulting in similar projects in
Mexico City and the highly profitable
São Paulo Tramway, Light and Power Company, whose holding company later acted as a holding company for all of the team's Canadian and global street car investments. As the partners recognised the need for clean electricity, they each became involved in local
hydro electric projects. Ross through investment became first president of the Mexican Power Company, which developed a hydro electric dam at
Necaxa to provide electricity for Mexico City.
Dominion Bridge, Coal and Steel In 1890, Ross replaced
Job Abbott as president of
Dominion Bridge Company, a major contractor to the CPR for replacing wooden bridges with stronger and lower-maintenance steel replacements. Although credited to the drive of Ross, vice-president
James Pawley Dawes led the development via joint-venture with the
St Lawrence Bridge Company to construct the
Quebec Bridge. Ross saw the great need for steel, and formed a syndicate to buy the
Dominion Coal Company. Investing in further shares independently, Ross built up such a huge stake in Dominion Coal that he was invited to join the board of the
Dominion Iron and Steel Company. However, his influence could not resolve a long contract dispute between the two for the supply of high-grade coal at a disadvantageous price, which resulted in a case review at the
High Court of Justice in London, England. Although fault was found on both sides, the contract was found to be legal. Ross resigned from both boards, thus allowing a later merger between the two companies. ==Private life==
