The railways were to build a line jointly from the Dundee and Newtyle station at Newtyle northwards and then diverge; the Coupar Angus line then ran west-south-west to that town, opening in February 1837. The Glammiss line would run east-north-east; it opened for goods traffic in 1837, and for passengers on 4 June 1838. The line from Newtyle station to the point of divergence descended at 1 in 100, but it was worked by horse traction, occasionally supplemented by locomotives. The two lines had the same gauge as the Dundee line and were worked in effect as branches of it. Marshall observes that "Neither line was ... successful in bringing in new business."
