From very early on, a branch line railway had been proposed to link Dunstable, Luton and St Albans with the new main line at Watford. However, for various political and economic reasons, the line was only ever to reach St Albans. Had the plan to extend the line to Dunstable and Luton ever been fulfilled, the line may have had a considerably different character from today's tranquil single-track railway.

The LNWR received parliamentary powers to construct the 6 mile, 32 chains long branch line on 11th February 1853. Work started in the early months of 1856 and the line was opened to public traffic on Wednesday 5th May 1858. By this time the LNWR had constructed a totally new and much bigger station at Watford, on the site where it has stood ever since.

Intermediate stations were initially planned for "Aldenham Road, Smug Oak and Park Street", but there were only two to begin with; at Bricket Wood and Park Street. Neither station served a large population centre, and in the summer of 1858 (a matter of months after opening), Park Street closed. It appears Bricket Wood temporarily befell a similar fate around 1859, but by 1861 both stations had reopened. 

Whilst Bricket Wood station has always been in the same place, the original site of Park Street is a contentious issue. It is thought that it may originally have lain very close to the Hyde Lane level crossing, which is now where How Wood station is to be found (opened 1988). A crossing keeper's cottage stood at Hyde Lane until the 1960s, and this may have been part of the original station building. The current position of Park Street, adjacent to the Watling Street overbridge, is thought to date from the 1890s.

In the late Victorian and early Edwardian eras, Bricket Wood became an unlikely tourist destination because of two funfares situated nearby. Hundreds of people passed through the station, particularly in the summer months, many of them on day trips to escape the crowds of London. An additional platform and 'passing loop' were installed by the LNWR at Bricket Wood in 1913, to cope with the large increase in excursion traffic. This allowed two trains to operate on the branch, and the new platform could accomodate up to 9 carriages. However, the funfares went into gradual decline in the 1920s, and the line never saw such a high level of traffic again. The passing loop and second platform were eventually demolished in 1966. Today's station is much closer in atmosphere to what it must have been pre-1913!

The Abbey line was the first railway that the ancient city of St Albans received. The people of the city were very supportive of the scheme, and the new terminus was a hub of activity. Known originally simply as 'St Albans', the name was only changed to 'St Albans Abbey' in 1924, to distinguish it from the former Midland Railway station now known as 'St Albans City' which was opened in 1868. In 1866, the Great Northen Railway also built a branch line, from Hatfield, that terminated at the station. Extensive sidings to the west served the local freight needs, not least providing space for the daily coal train that arrived to feed the adjacent municipal gasworks. The station buildings, although modest, provided a booking hall, waiting rooms and toilets for passengers, a far cry from today's simple waiting shelter! A 'run-round' loop was provided, which allowed locomotives to run round their carriages at the end of the journey, so that the loco was always at the head of the train. In later years an autotrain or 'push-pull' arrangement was used, whereby the driver could drive the train from a specially-converted carriage at the opposite end of the train from the loco. This dispensed with the need to 'run round' and was the precursor to modern operating methods.

Despite the substantial savings made by using diesel trains, in 1963 the 'Beeching Plan' proposed closure of the Abbey Line, along with hundreds of other similar branch lines the length and breadth of the UK. Luckily, strong local protest kept the line alive, and indeed the threat of closure as a heavy-rail operation has been lurking almost constantly every since. The line was to suffer heavily from rationalisation - almost everything save the track, formation and station platforms was demolished in the 1960s. 

Today, we are left with the most basic of 'basic railways'. It hasn't all been bad news though; since 1965, new stations have been opened at Garston and How Wood, and in 1987-88 the branch was electrified. In the late 90's, after a fierce battle to block the conversion of the line to a proposed 'guided-busway' system, a public consultation exercise resulted in resounding support for keeping the Abbey Line as a railway and a strategy that builds on its strengths as a local transport link. 

With that in mind, July 2005 marked the designation of the branch as a 'Community Railway' under the government's 'Community Rail Development Strategy', launched in 2004. Integral to designation was the inauguration of a Community Rail Partnership (CRP), set up by Herts County Council. Since this, various improvements have taken place to the fabric of the line, including the installation of a real-time passenger information system, the replacement of the level crossing at Watford North, and king of them all - the total refurbishment of St Albans Abbey station, such that it is now a tidy, modern, fully accessible station as befitting the 21st railway.

Long may the Abbey Line prosper!
