The Llanvihangel Railway was an early horse-drawn railway line in Monmouthshire which operated over a 6.25 mile route between the Brecknock and Abergavenny Canal and Llanvihangel Crucorney from 1814 until 1846.

[2] The line was initially constructed only as far as Blaengavenny and it was 1820 or 1821 before it was extended to Llanvihangel.

Two other similar but unsuccessful tramroad schemes were also promoted in 1810.

[4] The railway was constructed from a coal wharf on the canal east by way of Llanfoist, across the River Usk by means of a bridge constructed immediately adjacent to the existing road bridge, on its upstream side, but at a higher level above the river, then north past Abergavenny to the village of Llanvihangel Crucorney where it met with the Grosmont Railway.

[7] The company replaced them with a standard-gauge steam railway.
