Rugby station.
Services and operations
The majority of passenger services on the line are provided by
West Midlands Trains using

Class 319 units are used for peak-hour express services between Northampton and London Euston. The service consists of three 'semi fast' trains per hour between
London Euston and
Birmingham New Street. There is also an hourly local service between Northampton and Birmingham. Prior to December 2012 there was also a service to and from Crewe, but a few serve the loop line during morning and evenings and hourly on Sundays.
Avanti West Coast provide a small number of
Class 390 ''Pendolino'' services to London at the extremes of the day. But nearly all Avanti West Coast trains use the direct main line. Line speeds on the loop line are currently limited to

History

When the
London and Birmingham Railway (L&BR) was constructed in the 1830s, Northampton was by-passed, with the line running on high ground to the west via
Kilsby Tunnel. Traditionally, this was said to have been because wealthy Northampton landowners objected to
having a railway run through their land to reach the town.
However, an alternative view is that Northampton was by-passed because the
gradients would have been too steep for the early locomotives of the 1830s to easily cope with.
Robert Stephenson
Robert Stephenson , (honoris causa, Hon. causa) (16 October 1803 – 12 October 1859) was an English civil engineer and designer of locomotives. The only son of George Stephenson, the "Father of Railways", he built on the achievements of hi ...
the engineer of the London and Birmingham Railway was determined to avoid gradients steeper than 1:330 (that is 1
foot

of rising or falling gradient for every 330 feet of distance). As Northampton is located in the
Nene Valley, lower than
Blisworth, the closest point the L&BR came, connecting the town would have required gradients significantly steeper than this.
This meant however that Northampton, despite being a large town, did not have direct rail links to London. A branch from the main line was built to Northampton in the early 1840s: the
Northampton and Peterborough Railway, from
Blisworth, which gave the town indirect rail links to London and Birmingham.
The successor to the L&BR, 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 ...
(LNWR) decided to construct the loop line through Northampton in the 1870s. It was built as part of a wider scheme to double the capacity of the West Coast Main Line between and Rugby, by
quadrupling the track; however, routing the additional tracks on a deviation via Northampton had the advantage of giving the town a much better rail service, including a direct service to London, and avoiding the expense of widening
Kilsby Tunnel. The LNWR obtained Parliamentary approval for the line in 1875, and commenced construction in 1877. The line was opened for goods throughout on 1 August 1881, for passengers between Rugby and Northampton on 1 December 1881, and for passengers between Northampton and Roade on 3 April 1882. The loop line is a total of long, approximately longer than the direct line.
The loop line made use of the existing but small
Northampton Castle railway station which occupied part of the site of the historic
Northampton Castle. The station needed to be expanded as part of the works, this required the almost complete demolition of what remained of the Castle to make way for it.
Shortly after the completion of the loop line, the southern approach to Rugby station was remodelled, with a new
flying junction built near
Hillmorton, which allowed trains from the loop line to run into Rugby station without conflicting with trains on the fast lines.
The line was
electrified along with the rest of the WCML during the 1960s in the wake of the BR
1955 Modernisation Plan.
The
Daventry International Rail Freight Terminal (DIRFT); a major
rail freight interchange, was opened in 1996 with a rail connection to the loop line, and has been expanded several times since.

Proposed future development
Warwickshire County Council has proposed a new station on the Northampton Loop Line called
Rugby Parkway, which would be on the south-eastern outskirts of
Rugby serving the
Hillmorton area of the town, and the new housing development at
Houlton. The purpose of this would be to accommodate the future expansion of the town. The station was originally planned to open in 2019.
As funding was not secured, this deadline was not met. Nevertheless, in July 2019, Warwickshire County Council's Draft Rail Strategy for 2019-2034 proposed that the station would be opened between 2019 and 2026, with the possibility that at some point additional platforms could be provided on the 'fast' West Coast Main Line lines, in addition to the slow lines via Northampton.
Infrastructure
The Northampton loop starts at the northern end of
Roade Cutting. The line is double track and electrified throughout. There are three tunnels on the Northampton loop, the longest of which is
Hunsbury Hill Tunnel between Roade and Northampton, which is long.
There are two shorter tunnels between Long Buckby and Rugby, these are Watford Lodge Tunnel at ,
and Crick Tunnel at .
The line crosses the
Pulpit Bridge (or "Armchair Bridge") between Rugby and Long Buckby.
Accidents and incidents
*In January 1906, a young woman, 19 year old Lily Yolande Marie Rochaid, was found dead in Crick Tunnel, having fallen from the train she was travelling on from London to Rugby. A search was called after the train arrived at Rugby and it was noticed that the door of the carriage was open and no-one was inside. The circumstances of her death were never fully explained.
*Two
very similar railway accidents occurred on the Northampton loop in 1967 and 1969. The 1967 incident was near the village of
Milton Malsor between Roade and
Hunsbury Hill tunnel and the other in 1969 near the northern end of Roade cutting.
*On 20 March 1985, the body of 35 year old social worker Janet Maddocks was found beside the line to the north of Northampton station. Jack Roy, aged 15 at the time, was later convicted of murdering her and throwing her from a train.
