60021 at Huncoat and 66110 at Clitheroe

The video starts off at Huncoat Station with a 158 DMU passing followed by a track machine. Colas Rail 60021 is seen approaching Huncoat Station with the Preston Docks to Lindsey Refinery discharged tanks.
Moving to Clitheroe Cement Works, 66110 is seen arriving at Horrocksford Junction and then reversing back across the main line to allow it then once again to cross both lines into the cement works. The loco pulls the wagons into the sidings and then runs round its train and propels the train into the works.

Strange, why did It arrive on the "up" line then reverse into the "down line" and then head first into the sidings?
Suppose once it's been loaded it would have to be backed out again onto the up/down line?
Edit:
Never mind, I can see now the cross section of rail doesn't allow access to the sidings from that line, hence the required movement.
