now taken to the House of Lords. The House of Lords referred the matter back to the Railway and Canal Commissioners, and the latter gave an ambiguous judgement, but the ambiguity was sufficient for the NBR to take over the running of all trains north of Berwick from 14 January 1897. This meant that all long-distance passenger trains changed engines at Berwick, and the track layout there was inconvenient for the purpose; the NER owned the track right up to the southern end of the station, and the NER took care to make the engine changing process as difficult as possible. Taking advantage of the new light railway legislation, the remote community of Lauder gained its own branch line, the Lauder Light Railway, opened on 2 July 1901. Responding to the demand for residential travel to Edinburgh from the suburbs, the Corstorphine branch was opened by the NBR on 2 February 1902. There had long been a Corstorphine station on the main line; it was now renamed Saughton. Kincardine was developing as a port and the agricultural district on the Forth east of Alloa was considered to be remote. The NBR opened a branch line from Alloa to Kincardine; it opened in 1893. Although the area was entirely agricultural, the NBR responded to demands for a railway closing the gap, and the Kincardine and Dunfermline Railway, constructed and owned by the NBR, opened in 1906. Grouping of the railways In the final two years there were lengthy negotiation over war compensation, and negotiation over the share transfer into the LNER. In 1922 the North British had 650 passenger stations, and . There were 1,074 locomotives, and receipts amounted to £2,369,700 (passenger, ), £3,098,293 (mineral, ), and £2,834,848 (merchandise, ). After the passing of the Railways Act 1921, on 1 January 1923 the North British Railway was one of the seven constituents of the London and North Eastern Railway (LNER), along with the Great Northern Railway, the North Eastern Railway, and the Great Central Railway. (The rival Caledonian Railway and the Glasgow and South Western Railway were among the constituents of the London Midland and Scottish Railway.) Accidents and incidents On 10 August 1880, an express passenger train hauled by a North Eastern Railway locomotive was derailed north of Berwick upon Tweed, Northumberland due to defective track. Three people were killed. On 3 January 1898, an express passenger train collided with
