Later, a decision was made to retain the pier railway for the delivery of alumina and despatch of the finished aluminium ingots. The original railway, however, was not on a suitable alignment as it passed through the proposed site for Inverlochy village and also it crossed the A82 road on the level. Construction of a permanent pier railway commenced in 1927. It crossed the West Highland Railway on a bridge immediately west of Mallaig Junction. This bridge is still extant, although the embankment leading to it on the eastern side was removed in 2019.
