Newcastle and North Shields Railway's station at Carliol Square. Building a crossing of the Tyne was obviously going to be a lengthy process, so that he gave the construction of the general station a low priority. The Tyne crossing became the High Level Bridge. In February 1846 the Newcastle and Carlisle Railway exerted pressure for the general station to be built, and the architect John Dobson was appointed by Hudson to design it, in association with the engineer T E Harrison, and Robert Stephenson. Gibson Kyle was clerk of works. By now the general alignment of Hudson's railways was becoming clear: a main line from the south via Gateshead would approach over the High Level Bridge and enter the general station from the east; the Newcastle and Berwick line would be extended from Carliol Square and also enter from the east; through trains from London to Scotland would reverse in the new station. Newcastle and Carlisle Railway trains would of course enter from the west. A definite design Dobson produced general plans for the station, now being referred to as the Central station, on a broad curve to front Neville Street so as to accommodate the alignment of the approaching railways at east and west. It was to a "Romano-Italien design with ornamental work of the Doric order". Two through platform lines were shown, with three west end bays and two at the east end. There were to be three trainshed roofs with spans of 60 feet. Extensive offices as well as refreshment facilities were shown, and there was to be a covered carriage drive on the Neville Street side extending from the porte-cochère at each end. On 7 August 1847 a contract was let for the main part of the work to Mackay and Blackstock, for £92,000 (). A considerable amount of groundworks was necessary on the large site prior to the actual building work. The work did not progress speedily, and in 1849 Hudson's collection of railway companies suffered a financial shock. At a time of more difficult trading and a tighter money market, Hudson's personal dealings were exposed as shady. The York, Newcastle and Berwick Railway had been formed by merger of the previous smaller companies, and the YN&BR wished to reduce the financial commitment to the Central Station substantially; hotel accommodation and the covered carriage drive were eliminated. One of the through platforms was also removed
