In 1868, he entered into partnership with William David Nisbet (1837-1897) in Sunderland and Edinburgh. Commissions included a rail freight link, the Hylton, Southwick and Monkwearmouth Railway, transporting coal from collieries sited along the line to the nearby port at Sunderland. The railway was subsequently acquired by the North Eastern Railway. However, later railway designs were to prove more successful for Meik. In Scotland he designed a rail link to Eyemouth, an extension to the Forfar to Brechin line, the Newburgh and North Fife Railway and the East Fife Central Railway.
