On 24 March 1873 the W&TR opened to Glogue, and by October 1874 to Crymmych Arms. During the period 1859 to 1876, the P&TR had seen three different chairmen, two secretaries and three engineers. Due to the insolvency of the M&MR, in June 1879 the board joint board of company to investigate the costs of the railway. Szlumper was paid a salary of £150 per annum by the M&MR, and £80 for the P&TR. The board felt Szlumper had not fulfilled his duties properly, particularly after incorrectly engineering the M&MR junction at Pencader which was investigated by the Railway Inspectorate. He was replaced by Lionel R. Woods, formerly of the North Eastern Railway, in December 1879.
