By March 1855, the four engines ordered from the UK were all in service, with trains running every half-hour. They were named
Melbourne,
Sandridge,
Victoria, and
Yarra (after the
Yarra River over which the line crossed). Despite high construction costs, the railway was an immediate success, carrying 270,000 passengers and 28,135 tons of goods in its first full year of operations. In 1857, the Company opened a line from the present-day
Flinders Street station to
St Kilda to meet up with the St Kilda to
Brighton line being built by the
St Kilda and Brighton Railway Company. The name of
William Elsdon, the Engineer in Chief, who designed the line, is engraved into the parapet of the bridge at Park Street. Melbourne and Hobson's Bay Railway Company absorbed the two other remaining suburban railway companies in 1865: the
St Kilda and Brighton Railway Company and the
Melbourne and Suburban Railway Company. The combined company was incorporated as the Melbourne and Hobson's Bay United Railway Company. In turn it was sold, for £1,320,820, Both lines became part of the
Melbourne suburban electrified network during the 20th century. During the company's 13 years' existence, the average annual dividend of 7 per cent on working operations had resulted, equal to a return of nearly £49 on each £50 share. Most parts of the two lines were converted to
standard gauge light rail in 1987 as
tram routes 96 and
109. ==Rolling stock==
