From Pendre, the railway passes over a gated level crossing and runs beside an industrial estate before climbing up to Ty Mawr bridge and on to Hendy, the first of five minor halts, which serves the adjacent farm. The railway runs in an approximately north-easterly direction along the Fathew valley, mainly through fields of local farms on the valley floor, although this is where some of the steepest gradients on the line are to be found. The ruling gradient of the line is 1 in 60.
