History

The line was opened by the
London and North Western Railway
The London and North Western Railway (LNWR, L&NWR) was a British railway company between 1846 and 1922. In the late 19th century, the LNWR was the largest joint stock company in the world.
Dubbed the "Premier Line", the LNWR's main line connec ...

St Albans.
Originally, there were two intermediate stations:

In 1910, a station at Callowland opened, which is now known as '.
In 1924, the eastern terminus became known as ''St Albans Abbey'' to distinguish it from the

Past connections

The line was built in its current form, as a branch from Watford to St. Albans. However, the line was at times connected to two other lines. One, the
Hatfield and St Albans Railway, opened in 1865 from St. Albans Abbey station to the

at Hatfield. Mostly a local route, the construction of the Midland Main Line ensured that it never became popular with the critical market of passengers to London. It closed to passengers in 1951, as part of a cutback of minor routes after the war. The whole route closed to goods in 1964, although a short stub at the Hatfield end lasted until 1968.
During construction of the Midland Main Line in the 1860s, a branch was laid from near How Wood to the Midland route to carry building materials. Never used by passenger services,

Stations on the branch are unstaffed. Some have ticket machines; otherwise tickets must be bought on the train. Passengers starting their journey at Watford Junction, which is staffed, must have a valid ticket prior to boarding the train, in compliance with National Rail conditions of carriage.
The Abbey line is part of the
Network Rail Strategic Route 18, SRS 18.10 and is classified as a Rural line.

Signalling
Signalling is under One Train Working (without Train staff) rules, where only one train is allowed on the line at a time. Trains can be moved into Watford Junction yard by a manual ground frame there. On 28 October 2005 its incorrect operation caused an incident with a train not in passenger service.

Future developments
Since 1995 the Abbey Flyer Users Group (ABFLY) has been campaigning to secure the future of the line and encourage its growth. The Abbey line was designated by the Strategic Rail Authority as a community rail

from 2011. It was hoped that this would be possible for the same amount of subsidy the line received, as the new infrastructure required, such as a passing loop would be cheaper for light rail than heavy rail.[ Longer-term proposals envisaged extensions into Watford town centre via Clarendon Road and High Street, and St Albans city centre, possibly as far as St Albans City railway station, and possible re-instatement of the line to Hatfield.]
The light rail plan was cancelled in May 2013, as it was found to be impossible to deliver the scheme within the existing heavy rail subsidy as planned and more complicated than had been expected with disputes over apportionment of ticket revenue and who was responsible for the cost of maintaining structures. Hertfordshire County Council pledged to prepare a more ambitious bid to the DfT for funding for full segregation from the national rail network and extensions on either end rather than to lease the line from Network Rail.
In a Draft Rail Strategy consultation published in June 2015, Hertfordshire County Council highlighted the difficulties presented by single-track operation on the Abbey line, in particular the fact that the maximum service frequency that can be operated is one train per 45 minutes. The report notes that the service pattern makes it difficult to enable interchange connections with other rail services and to offer a "clockface" timetable that is memorable to passengers. Among the solutions evaluated by Hertfordshire are: a proposal to reopen the passing loop at Bricket Wood; running trains which skip certain stations; closing some stations; conversion of the line to light rail

operation; and conversion of the line to a guided busway. The passing loop solution would enable a 30-minute service, but the report notes that there would be an additional cost of running the line with two train sets (rather than a single train, as at present), and that it would be "difficult to achieve a favourable business case". The report states that a light rail or busway solution would be quicker to implement and offer higher service frequencies, while still providing sufficient capacity, and concludes that these alternative modes would offer a stronger "business case" than heavy rail. The ABFLY campaign group has criticised the busway proposal, citing environmental concerns about replacing an electric train service with a diesel bus service and rejecting plans to replace the tracks with a concrete busway.
Other proposals considered included adding the Abbey line as a branch of the proposed extension of Crossrail

to St Albans; this proposal was rejected due to the technical challenges associated with upgrading the Abbey line to accommodate Crossrail trains.
Passing loop
In May 2020, it was announced that £50,000 of funding from the government's Restoring Your Railway Fund would be available to enable transport planners to develop a business case around the Bricket Wood passing loop proposal. If approved, this scheme would have enabled an increase in train frequencies, as well as the introduction of a regular "clockface" timetable. In June 2022 it was announced that further funding had been refused and the passing loop scheme would not be taken forward.
Rolling stock
Upon winning the West Midlands franchise in 2017, the future operator West Midlands Trains confirmed that new trains would be bought for the Abbey line.East Japan Railway enters UK market with West Midlands franchise win
