The original Portadown station was sited half a mile east of the present station and opened on 12 September 1842, replacing a temporary station at Seagoe that had opened the preceding year. The Portadown station was moved to the present location in 1848 then reverted to its original site between 1863 and 1970. Goods traffic ceased on 4 January 1965. The present station opened in 1970, replacing a large and largely redundant station. At the time (1970) the station was called
Portadown - Craigavon West, a title that was quietly dropped after the "new city"
Craigavon failed to materialise. The layout of the 1970 station was modified in 1997 to allow bi-directional working on all three platforms. The lines to
Cavan via
Armagh (closed 1957), and
Derry via
Dungannon and
Omagh (closed 1965) diverged immediately west of the present station. In 2012, work began on a major refurbishment of the station. A new, modern building was constructed and a footbridge replaced the subway. The refurbishment was completed in 2013. ==Layout==
