How long are the Neath and Tennant Canals?
Neath and Tennant Canal
From the northern terminus, a tramway connected the canal to iron works at Aberdare and Hirwaun. This was built in 1803, and included an incline just north of Glynneath, which was powered by a high-pressure Trevithick steam engine.[4] The Tappenden brothers had bought into the iron industry in 1802, and built the tramway because of high tolls on the Glamorganshire Canal,[8] but by 1814 they were bankrupt, and had no further connections with the canal.[4]
