When coal deposits were confirmed in today's
Cumberland area, the plan was a railway line to a wharf at today's
Royston. When
Robert Dunsmuir acquired the operation in 1887, and formed the Union Colliery Co., the track surveyors were redirected farther down the coast to today's Union Bay. The deep-water bay was better suited than Royston's shallow harbour. The
standard-gauge railway line, which included a long
howe truss across the Trent River, was completed in 1889. In 1898, the bridge collapsed, plunging a
mixed train over into the river. Seven died and two were seriously injured. The twice weekly passenger service soon became daily. From 1929, only passenger services for shift workers remained, which buses replaced in 1946. Special trains remained initially for the annual picnic. In May 1914, the railhead for the northward extension of the
E&N Railway reached Union Bay. Prior to the construction, a horse team took two days to travel from
Parksville to Union Bay. In 1965, a Dayliner passenger train smashed into a freight car north, injuring four. In 1979, when a
CAT machine inadvertently damaged track at Mile 129 (a mile south), police warning lights alerted a northbound Dayliner passenger train to stop before a likely derailment. Union Bay was a flag stop when
Via Rail on Vancouver Island ceased in 2011. Adjacent stops were about south to
Buckley Bay, and north to Courtenay. At the railway crossing on McLeod Rd, not even a signpost marked the flag stop location in its final years. ==Former wharves==
