Goods traffic started on the main line from 12 December 1850, and the Hitchin to Royston line was opened on 21 October 1850; this was extended to Shepreth on 3 August 1851. Captain Mark Huish had been appointed General Manager of the London and North Western Railway on its formation in 1846. Huish was a skilful railway diplomat, and while his methods were generally more proper than Hudson's, they were aggressive in finding means of disadvantaging competitors, such as the GNR.
