Heavy expenditure on enhanced signalling and other works were incurred by the PPR, to be paid for by the G&PJR. However that Company was in deep financial difficulties, even more so than the PPR, and the matter went to the Court of Session. Notice of Interdict was served on 1 February 1882 and from 7 February G&PJR trains were not allowed to run over the PPR. The G&PJR terminated both passenger and goods trains at New Luce and the gap was covered by road transport.
