_London & North-Western_ (1846, an amalgamation of the London & Birmingham, Grand Junction, and Manchester & Birmingham lines).--Terminus and offices, Euston. Main line--Rugby, Crewe, Warrington, Preston, Carlisle; forming, with the Caledonian system, the "West Coast" route to Scotland. Serves also Manchester, Liverpool and all parts of the north-west, North Wales, Birmingham and the neighbouring midland towns, and by joint-lines, the South Welsh coal-fields. Maintains docks at Garston on the Mersey, a steamship traffic with Dublin and Greenore from Holyhead, and, jointly with the Lancashire & Yorkshire Company, a service to Belfast, &c., from Fleetwood.

Main line--Rugby, Nottingham, Leicester, Sheffield, Manchester. The former main line runs from Manchester and Sheffield east to Retford, thence serving Grimsby and Hull, with branches to Lincoln, &c. The main line reached from London by joining the line of the Metropolitan railway near Aylesbury and following it to Harrow. Subsequently an alternative route out of London was constructed between Neasden and Northolt, where it joins another line, of the Great Western railway, from Acton, and continues as a line held jointly by the two companies through Beaconsfield and High Wycombe. Here it absorbs the old Great Western line as far as Prince's Risborough, and continues thence to Grendon Underwood, effecting a junction with the original main line of the Great Central system. This line was opened for passenger traffic in April 1906. The Great Central company owns docks at Grimsby.
