[5] Gilwern first appeared in Bradshaw in April 1863, however the line's engineer, John Gardner, had reported on 27 January 1863 that it was due for completion in three or four weeks and on 6 August he confirmed that it had been open for five months which suggests the actual opening took place in late February or early March.

[7] It was reached from the east on a 1 in 37 climb from Govilon with the line rising 150 feet (46 m) in less than 2 miles (3.2 km).

[11] To the east was Gilwern Stone Quarry which was served by a siding branching off from the Down line.

[13] Decline in local industry and the costs of working the line between Abergavenny and Merthyr led to the cessation of passenger services on 4 January 1958.

The platforms have survived and the trackbed through the station is part of National Cycle Route 46.
