Background and design


The appearance of the train is the work of British designer Kenneth Grange
Kenneth Grange
Kenneth Grange, CBE, MCSD, RDI, is a British industrial designer.Grange’s career began as a drafting assistant with the architect Jack Howe in the 1950s...

. Grange was initially approached just to design the livery for the train, but under his own impetus decided to redesign the body working with aerodynamics engineers. He went on to present the new design to British Rail and persuade them to adopt it.

An InterCity 125 consists of two Class 43 diesel-electric power cars and a set of Mark 3 coaches (typically 7 or 8). Normally there are two types of HST sets, 8+2 (5 standard class, 1 buffet, 2 first class) and 7+2 (4 standard class, 1 buffet, 2 first class), where the +2 refers to the power cars at each end of the rake.

Key features of the design are the high power-to-weight ratio of the locomotives (1678 kW per ~70-tonne loco), which were purpose-built for high-speed passenger travel, improved crashworthiness over previous models, and bi-directional running

Push–pull is a mode of operation for locomotive-hauled trains allowing them to be driven from either end.A push–pull train has a locomotive at one end of the train, connected via some form of remote control, such as multiple-unit train control, to a vehicle equipped with a control cab at the other...

 a rake of the new 23-metre-long Mark 3 coaches. These trains would be designed by the Chief Mechanical and Electrical Engineer's Department, also in Derby, and were originally intended as a stop-gap until the APT was proven.

The prototype train of seven coaches and two locomotives was completed in August 1972. By the autumn it was running trials on the main line and in May 1973 the prototype, now designated Class 252

, set a world diesel speed record of 143.2 mph (230.5 km/h). The concept was proven in trial running between 1973 and 1976, and British Rail decided to build 27 production HSTs to transform InterCity services between London Paddington, Bristol, and South Wales.

Production


The first production power car, numbered 43002, was delivered in late 1975, with a significantly different appearance from the prototype. The streamlined front end lacked conventional buffers, and the drawgear was hidden under a cowling. The single cab window was much larger than the prototype's, and there was no driving position at the inner end.

Deliveries continued through 1976, and in October a partial service of HSTs running at 125 mi/h began on the Western Region. A radical update of the standard BR livery on the power cars was complemented by the 'Inter-City 125' branding, which also appeared on timetables and promotional literature. By the start of the summer timetable in May 1977, the full complement of 27 Class 253

sets (253001 – 253027) was in service on the Western Region, completely replacing locomotive-hauled trains on the Bristol and South Wales routes. Passenger volumes on the trains rapidly increased due to the speed and frequency of the service, an effect previously seen only when electric trains had replaced diesel or steam services.

 services. Initially, British Rail planned to fit uprated 2500 bhp Valenta engines to these longer HSTs, but this plan was shelved as the intensive running on the Western Region began to result in a high level of engine failures, often due to inadequate cooling; for a while, the WR power cars were derated to 2000 bhp.

 from the summer timetable in May 1978. Within a year they had displaced the Deltics to lesser workings and reduced the London-Edinburgh journey time by up to an hour.

Production of HSTs continued until 1982, allowing them to take over services from London to the West Country, many Cross-Country express trains, and finally the Midland Main Line

. Ninety-five HST sets including 197 Class 43 powercars were built between 1976 and 1982. More Mark 3 trailer cars were built in the 1980s for the Western Region Class 253s, making them eight-car rakes in common with those used on East Coast and Midland Main Line services. During the 1990s only the Cross-Country sets remained as seven-car rakes, with just one first-class carriage.

Introduction of units


Until the HST's introduction, the maximum speed of British trains was limited to 100 mph (160 km/h). The HST allowed a 25% increase in service speeds along many lines they operated. British Rail initially used the fleet starting in 1976 on the Great Western Main Line

. Not only did the HST bring considerable improvements in service on the railways, British Rail entered a period of active marketing which accompanied and supported the train's success.

The lighter axle loading allowed the trains to travel faster than conventional services along lines not suited to full-speed running, such as the Edinburgh to Aberdeen line. Known as HST differential speeds, coupled with superior acceleration capability over older locomotives, this allowed substantial cuts in journey times over these lines. The increased speed and rapid acceleration and deceleration of the HST made it ideal for passenger use. The prototype InterCity 125 (power cars 43000 and 43001) set the world record

Units for services in the M4 corridor/Thames Valley to Bristol, Hereford, Oxford, Exeter and Cardiff were converted into a high-density layout of mostly airline-style seats (only two tables per coach). This was in order to provide more seats for commuters. The remainder (for the routes to Swansea and the West Country) kept the tables.

The refurbished coaches have new seating (leather in first class), at-seat power points and a redesigned buffet bar.

s, and were allocated British Rail Class 253 and Class 254 for Western and Eastern Region services respectively.

British Rail considered the HST, a fixed formation train with a locomotive at each end, as a multiple unit on introduction, and numbered them as such: 253 xxx (Western Region) and 254 xxx (Eastern and Scottish Regions). However, because two power cars carried the same 'set number', problems arose when, for servicing reasons, different units were used on a train, which would then display a different number at each end. For this reason, British Rail abolished the initial numbering system and all individual power cars became identified as such, using the format 43 xxx - this number was previously carried in small digits in the bodysides, prefixed by a 'W' for Western, 'E' for Eastern or 'Sc' for Scottish to identify the region, thus the power cars were reclassified as Class 43

Livery


The original "Inter-City 125" livery was blue and grey, with a yellow front to improve visibility which continued down the side of the power cars.

The second livery had mostly grey power cars with a white band along the middle, yellow underneath the white band, with the InterCity colours (cream, red, white, brown) for the parcel compartment of the power cars and the coaches.

There was brownish-grey, dark grey (almost black) around the windows with a red and white stripe below the windows, and retaining the yellow bands on the power cars. The final variant of this livery saw the yellow side-bands replaced with white and did not feature the British Rail name or logo: it carried the new sector branding Intercity logo

, train operating companies painted the HSTs in their own colour schemes, with some lasting longer than others.

Public reaction


The Intercity service proved an instant hit with the British public. By the early 1980s the HST had caught the travelling public's imagination, thanks in part to a memorable television advertising campaign fronted by Jimmy Savile

International attention


The success of the HST has had significant international impact. This impact is most obvious in Australia, where the HST was used as the base for developing the XPT, in cooperation with British Rail.

At Ladbroke Grove and Ufton Nervet the accidents were ultimately caused by factors not involving the HST sets or their drivers, although the set involved in the Ladbroke Grove crash had a faulty AWS system; however, the Southall accident was the result of the driver of the HST passing a red signal without stopping

Additionally many operators undertook some sort of reburbishment programme on the Mark 3 carriages in the early 2000s. With the long-term delay and change of direction of the HST2 programme, operators began to refurbish their HST fleets in 2006 - both by remotoring with the more modern MTU4000 diesel generator, and by refurbishing the carriage interiors. It is anticipated that these overhauls will give the HST at least another 10 years in front-line service.

.

These new DMUs have better acceleration than the HST due to a higher power/weight ratio, with greater efficiency and braking performance in addition. However, passengers are often annoyed by the vibrations and the level of noise onboard many DMUs from the underfloor engines, compared to the much quieter Mark 3 coaches.

In 2005 the initial concept of HST2 was rejected by the Government and the rail industry as a like-for-like replacement for the HST fleet. In light of this rejection, in 2006 existing operators turned to refurbishments of the Intercity 125 trains.
