There was a level section of long, after which the Balbeuchly incline rose at 1 in 25 for . A further level section followed, also of to Hatton. The final incline descended to Newtyle at 1 in 13 for . The track gauge was and fish-bellied rails were used, of on stone blocks. The inclines were all straight; the Law incline was laid with three rails at the top, four in the central section and two at the lower end; a high pressure engine was provided. The Balbeuchly incline had only a single track and was worked by a condensing engine; the Hatton incline also had a single track and had a similar engine. A newspaper advertisement stated that the line had been opened for traffic on 16 December 1831, but this was only on the upper levels, not including the Law and Hatton inclines; the extension to the full extent of the line was reported to have taken place on 3 April 1832. 2,645 passengers were carried during April 1832.

In fact passenger traffic became remarkably buoyant, notwithstanding the lack of attraction at Newtyle. The company introduced a variety of season tickets, and workmen's fares conveying sheep shearers at cheap rates as well as excursionists. The original passenger coaches were said to be old stage coach bodies set on trucks. "Outside" passengers travelled on the roof of the coaches. In fact Marshall states that two old "Tally-Ho" coaches that had been operating on the Perth turnpike, which were fixed to a wagon chassis.
