[1] Buntingford is located on Ermine Street, the road from London to Cambridge and the north, and had a prime position as a trading town before the advent of railways.
[2] The town was bypassed by the main line of the Eastern Counties Railway from London to Cambridge via Bishop's Stortford, which opened in stages between 1840 and 1845.
In 1847 George Hudson promoted a Parliamentary Bill for an alternative route to Cambridge, leaving the Hertford branch at Ware and running via Buntingford and Royston to Shelford which failed to gain approval.
A local promoter, George Mickley, estimated £70,000 to construct ten miles of single track railway and £30,000 for land and stations, making a total of £100,000.
The Bill passed through Parliament and the Royal Assent was granted for the Ware, Hadham and Buntingford Railway on 12 July 1858 with authorised share capital of £50,000.
[3][2][4] A tender of £44,000 to build the line was accepted from W. S. Simpson of Ely; the engineer was Henry Palfrey Stephenson and the first sod was cut at a ceremony on 20 July 1859.
A deviation Bill was submitted in 1860 to improve the gradients and shorten the line which gained the Royal Assent on 22 July 1861.
The directors considered mortgaging the line, but it proved impossible to find a financial house willing to take debenture shares and the company lacked funds.
He was critical, the permanent way was below the required standard and the underbridges were badly constructed, one at Bog Ford Bridge, was reported to have sunk three inches under the inspection train, there were no facing point indicators, no turntable at St Margaret's, and several stations had no distant signals.
The work committed the company to considerable unforeseen expenditure and a further Act of 22 June 1863 obtained authorisation to take an additional £40,000 share capital.
[3][2][6] Goods trains caused congestion on the single line, and the board decided that a passing loop at Hadham was required; expenditure of £220 was authorised 24 May 1865; the work was to be done by the GER at the Buntingford company's expense.
The company was unable to pay, and Bentinck took them to the Court of Chancery where he obtained judgment in his favour for £3,039, "payable in land if not in cash".
Its motivation was that the Great Northern Railway might get control of the Buntingford company and use it to gain entry into GER territory.
[3] Shareholders of the Buntingford Company met on 26 March 1867 and voted in favour of selling to the GER; the deed of transfer was ratified on 30 July 1868, effective on 1 September 1868.
[3][2] Due to poor usage, Widford station was closed after 31 December 1868 but a petition was raised locally and it reopened on 1 April 1869.
Safety improvements were demanded by the Board of Trade, and the block telegraph system was installed between St Margaret's and Mardock, operational from June 1888. it was extended to the end of the line between 1892 and 1893 at a cost of £15,277.
