Chiltern Railways originated with a number of former British Rail managers who sought to conduct a management buyout on one of the soon-to-be-created rail franchises that would be produced as a part of the

In October 1995, ''M40 Trains Limited'' which was established; the various railway managers held a combined 51% shareholding in the business, while the John Laing Group and 3i held 26% and 23% stakes respectively. The company reportedly spent £38 million in its bid for the Chiltern Railways franchise. In June 1996, the

awarded the franchise to M40 Trains for an initial period of seven years. It was the only franchise operator to have as many as 51% of its shared controlled by its directors. On 21 July 1996, the company commenced operations, taking over from the publicly owned British Rail. Chiltern Railways was the first railway franchise to order new rolling stock in the post-privatisation era in the form of the Class 168 ''Clubman''

s (DMUs). However, their introduction was marred by unreliability, in part due to their rushed entry into service in respond to booming passenger demand. By April 1999, the company claimed to employ 50% more staff than it had at the start of the franchise, and to be running 25% more services than had been operated by British Rail. Meanwhile, under the terms of the franchise agreement, the annual subsidy provided by the British government was gradually reduced. During early 1999, the ownership of M40 Trains underwent substantial changes; the John Laing Group opted to increase its shareholding in the venture to 84% via the purchase of shares from their previous holders; the outstanding 16% of shares were owned by several members of the former British Rail management team. During March 2000, the Shadow Strategic Rail Authority announced that both M40 Trains and the British transport group Go-Ahead had been shortlisted to bid for the next Chiltern franchise. In August 2000, M40 Trains was awarded the new franchise, which was set to run for 20 years, conditional on various investments being made across that period. On 3 March 2002, the new franchise period commenced. In August 2002, John Laing acquired the remaining 16% of shares in M40 Trains that it did not already own. In September 2006, John Laing was purchased by the global investment firm Henderson Equity Partners in exchange for £887 million. During December 2004, Chiltern Railways took over operation of passenger services on the to branch line from

Performance

Chiltern Railways' early operations were subject to considerable criticism. During 1998, its poor performance figures in criteria such as reliability, punctuality, and customer approval has led to financial penalties being incurred by the company, some of which was in the form of refunds to its passengers. By the mid-2010s, Chiltern was considered one of the best railway operators in Britain, with

(PPM) regularly over 90%, until the introduction of changes in November 2015, and infrastructure issues saw punctuality fall to 86% in December 2015. Chiltern's PPM is measured on stricter conditions than its long-distance rivals, such as

, as Chiltern has a five-minute window for performance while others have a ten-minute window. Performance figures published by Network Rail rate Chiltern Railways sixth in train operating companies in the UK at 89.4% (PPM – period 9) and 94.3% (MAA) for the year to 12 December 2015. A new timetable introduced in September 2011, combined with significant disruption caused by engineering work, caused a negative reaction from customers. A petition to have the service reviewed was started, and articles describing the disrupted journeys of commuters appeared in the local press. A new timetable introduced in December 2012 also met with frustration and opposition from some customers, particularly those using Saunderton and Princes Risborough stations.

agreed in January 2010 to a £250million upgrade of the Chiltern Main Line.

Phase 1

Phase 1 of the project, now complete, involved upgrading the Marylebone – Birmingham Chiltern Main Line to permit running on an additional of route. Junctions at Neasden, Northolt and Aynho were remodelled to permit higher speeds. The 'up' through track has been restored at , the existing 'up' line becoming a platform loop, a new turnback siding has been provided at , and a new, straighter 'down' through track built from Northolt Junction (where the original layout favoured the now little-used Paddington route) to Ruislip Gardens. The existing 'down' track continues to serve station. The former speed restrictions through have been removed to permit 100mph running. Two additional terminating platforms at Birmingham Moor Street were reopened in December 2010. Accelerated services were initially planned to start in May 2011, but there were delays and it was not until 5 September 2011 that Chiltern was able to introduce a new timetable to take advantage of the improvements. As a result of the speed increases, journey times have been reduced significantly. From Marylebone, the fastest peak-hour journey time to Birmingham Moor Street is now 90minutes, instead of 117minutes previously. Chiltern Railways former chairman

A new station, , has been constructed at Water Eaton; the service between Oxford Parkway and London started on 26 October 2015, with the link from Oxford Parkway to becoming operational on 12 December 2016.

Rolling stock

Chiltern Railways inherited a fleet of 34 Class 165 ''Turbos''

units were installed throughout the fleet, while the hopper opening windows were removed; a first-class seating area was also implemented. As the fleet had been designed for suburban use, rather than InterCity travel, the Class 165s tend to be concentrated on services to Aylesbury and Banbury, although this stock can also be found operating the service between Birmingham and Leamington Spa. Chiltern ordered several batches of Class 168 ''Clubman'' DMUs. Between 1998 and 2004, these entered revenue service, the company eventually operated nine three-car and ten four-car sets. These operate across the network. During April 2003, Chiltern restored a single Class 121 ''Bubble Car'' for use on the to shuttles. In May 2011, a second Class 121 followed after being overhauled at

. During March 2013, a third Class 121 (121032) was acquired from Arriva Trains Wales for use as a spare parts donor. On 19 May 2017, the Chiltern Bubble cars ran for the last time, as their age made spare parts increasingly difficult to obtain. In January 2008, Chiltern ordered four two-coach Class 172 ''Turbostars''; these entered service during June 2011. Because they cannot be fitted with the tripcock safety equipment necessary to operate on

lines, none of the Class 172s can operate via unless attached to a Class 165 or Class 168 DMU. Although initially intended for use on all-stations services out of London, they frequently operated as far afield as Birmingham. During mid-2021, all of Chiltern's Class 172s were leased to

The company promoted the HybridFlex as increasing acceleration while reducing fuel consumption, vibration, and noise emissions, along with lessening the environmental impact of rail travel.
