Its Act of Parliament on 10 May 1844[1] authorised it to build a line between Norwich and the small town of Brandon, actually just across the border in Suffolk.
The line from Norwich to Brandon was constructed by Messrs Grissell & Peto, and the engineers were Robert Stephenson (1803–1859) and George Parker Bidder (1806–1878).
Construction of the 40 miles were completed with a ceremonial opening on 29 July 1845, at the same time as the Eastern Counties Railway celebrated their through route from Shoreditch, London, to Brandon, albeit via the leased Northern & Eastern Railway line from Stratford, London to Newport; the regular passenger service followed on 30 July 1845.
The first temporary terminus was just west of the River Wensum, pending the completion of the Trowse swing bridge which was achieved in December 1845.
Generous provision was made for the maintenance of locomotives at Brandon with a six road engine house being provided although once the ECR took over the NR in 1848 the shed's role was diminished as there was no longer a requirement to change locomotives there as they worked through to or from Norwich.
