The
Peterborough railway line was built from a new junction at
Roseworthy (north of Gawler on what was then the
Morgan railway line) to
Tarlee during 1868. A bridge was required over the River Light. The bridge was long and high, in two spans on stone abutments and a cast iron cylindrical pier in diameter. This bridge was replaced in 1925 in conjunction with the works to convert the narrow gauge line to broad gauge, despite this bridge already being broad gauge. Elevation is .

Balaklava on the narrow gauge
Port Wakefield railway line created the
Balaklava railway line through
Owen to meet the broad gauge line at Hamley Bridge. This was built to , so Hamley Bridge was a
break of gauge station rather than a junction. A new railway station was established a few hundred metres north of the original in 1880 and was at first known as Alma Railway Station. The stone building, occupied as a private residence today, represents the fine architecture of the era and is heritage listed along with the signal box and water tanks, and two of the bridges over the River Light. As Hamley Bridge is only from the capital and major port, this break of gauge soon became a sore point, leading lobbying over decades to extend the narrow gauge all the way to the capital and that port. Trains reaching Hamley Bridge may have travelled from
Oodnadatta, thus illustrating the poor design of this break of gauge. The break of gauge at Hamley Bridge was very cramped and poorly sited due to rivers, bridges, gradients and curves, which were difficult to improve upon. There were also shunting delays and a shortage of trucks. A counter proposal to ease congestion at the inadequate facilities at the Hamley Bridge break of gauge was to shift the break of gauge northwards to
Balaklava, was strongly opposed. Alternately, the break of gauge may have been moved northwards to
Owen Hamley Bridge ceased to be a break of gauge station in 1927 when narrow gauge lines as far north as
Gladstone were
converted to broad gauge, Gladstone becoming a break of gauge station in lieu. Regular passenger services ceased in December 1986. Freight trains continued to use the line until October 2005. 24-hour per day operation was made possible by the installation of
floodlighting in 1908. == Media ==
