Very few details are known about this route. The formation was reused by POR south of Hoel Y Sheet (6.55 on POR), except for a minor diversion at Smoky Cot. POR used its own but similar formation to north of SWM2, and then the same route to Cefn Junction (2.44 on POR). North of here, DLT was a very different route, though broadly parallel to OVE and BAL. Finally, DLT gave its formation to CNZ (from 9.21 on CNZ) almost to the end of the line, from where DLT diverged to serve Duffryn colliery.
