[6][7] The village had a long association with tramroads, the Trevil Rail Road having been established in May 1793 and operating from 1797.
[9] The Rassa Railroad ran from Trevil limestone quarries to the north-east, under the Merthyr and Abergavenny line, and to the Beaufort Ironworks.
[9][10] The works and five collieries comprising 57.5 miles (92.5 km) of private mineral lines were purchased by Richard Thomas & Co. in 1935.
[8] Trevil station was in an isolated location, situated just to the south of the Castle Inn.
[6] As a result of decline in the local industry and the costs of working the line between Abergavenny and Merthyr,[16] passenger services ended on 4 January 1958.
