31 December 1962. On the same date, the services from Hereford and Moat Lane were also closed down, so that Brecon had no passenger train service. There remained a Caerphilly – Machen – Newport unadvertised service for workmen as the only passenger operation on the B&MR network; that too closed on 1 July 1963. Goods and mineral traffic between Deri Junction and Pant was withdrawn on 5 August 1963, followed by that between Brecon and Merthyr, and also Pontsticill and Dowlais Central, on 4 May 1964. Brecon continued as a non-rail-connected coal depot until 9 November 1964. Bedwas to Pengam closed completely on 31 December 1962. The Waterloo section of line, built to ease gradients and congestion approaching Machen, was closed on 20 July 1964, but the residual freight traffic was diverted through Radyr and the Caerphilly to Machen section closed from 20 November 1967. Ogilvie Colliery on the Deri line remained in use until 3 September 1978. By 1980 only one short section of survived, serving coal traffic to Bedwas Navigation Colliery, from Newport via Bassaleg and Nine Mile Point. When the Bedwas colliery closed, the section of the branch between Bedwas and Machen was also closed, in 1985. The section between Machen and Bassaleg Junction has experienced sporadic stone traffic from Hanson Aggregates' limestone quarry, east of Machen. 1878 accident The B&MR was subject to a number of accidents; the extreme gradients were often a cause. On 2 December 1878 a particularly tragic accident took place. A goods and mineral train was descending the seven-mile bank, and inadequate wagon brakes had been applied. The train got out of control, and derailed near Talybont, running down the embankment slope. The train consisted of 22 wagons of coal, three of goods, 11 empties, and a brake van; it was worked by three 0-6-0 saddle tank engines; the aggregate weight of the train was 397 tons. Two drivers and two firemen were killed. Rolling stock Initially, the B&MR was worked by the contractor Thomas Savin, who provided locomotives and rolling stock from a fleet that was also used to work several other Welsh lines, such as the Mid Wales Railway. Savin went bankrupt in February 1866 and fourteen of his 56 locomotives then came into B&MR ownership. Whilst the B&MR was absorbed by the GWR on 1 July 1922, its locomotives were not taken into stock until the four-week period that
