A more modest scheme, the Inverury and Old Meldrum Junction Railway was promoted; its necessary capital was £22,000, and the GNoSR promised a moderate contribution. The authorising Act for the Inverury and Old Meldrum Junction Railway received the Royal Assent on 15 June 1855. The line was to be 5 miles 1194 yards in length, from a junction at Inverurie. The station at that time was some distance south of the present one; the Oldmeldrum branch line ran alongside the main line for nearly a mile before diverging. The engineer was
John Willet. There were few engineering complications in constructing the line, the biggest work being a 50-foot girder bridge over the
River Ury. The capital for construction seems to have been raised mainly locally, and so construction was completed quickly and cheaply, being ready by June 1856 at a low cost of about £5,000 per mile.
Colonel Yolland carried out the necessary inspection for the
Board of Trade on 23 June 1856. Everything was satisfactory and a ceremonial opening to passengers took place on Thursday 26 June 1856. There was an intermediate station at Lethenty, opened on 1 November 1856; a platform halt was established at Fingask, where there were wool-carding mills, in 1866. ==Financial performance==
