In 1835 the Newcastle and Carlisle Railway (N&CR) Act authorised the line to approach Newcastle to a terminus at Redheugh, on the south bank of the River Tyne, close to the end of the present-day New Redheugh Bridge. The Act also authorised a crossing of the Tyne there, giving rail access to the north shore quays. The river was shallow at this point, and the bridge would have been at a low level, only above high water. The line would then have climbed to a terminus at the Spital, near Neville Street and the east end of the present-day Newcastle Central station. The climb was to be at a gradient of 1 in 22 and would have been operated by a stationary steam engine with rope haulage.
