One hundred and ninety seven (197) class 43 power cars were built at BR's Workshops at Crewe in the period from 1976 to 1982. The class 43 power cars run at each end of a set of purpose built carriages. Originally the trains ran as dedicated sets and were allocated fixed set numbers as classes 253 or 254. The main difference between the two classes being that they ran with either seven or eight carriages. This arrangement was soon found to be inflexible and the fixed formations were abandoned. The trains are capable of travelling at 125 miles per hour and sets are therefore commonly referred to as HST's or 125's.

In May 1985, displaying the much loved yellow and blue livery, InterCity 125 'HST' set with class 43 power car No.43164 is about to pass the Lickey Bankers (Nos.37219 & 37241) at the stabling point at Bromsgrove in May 1984. Photograph by Andrew Smith.

In April 1986, class 43 power car No.43029, in BR InterCity 125 livery, was photographed by Andrew Smith, at Worcester Shrub Hill Station on a 'down' express from London Paddington to Great Malvern.

In Virgin Trains livery Class 43 power car No.43084 (with No.43079 at the rear) was photographed approaching Kings Norton Station on 25th April 2002. Photograph taken by Andrew Smith.

On 24th October 2008 Andrew Smith photographed class 43 power car No.43129 as it crossed the railway bridge at the end of Sling Lane in Malvern. Photograph taken on 24th October 2008.

The Cross Country Trains livery is perhaps the worst ever carried by the 'HST's but is seen here at its best in this photograph taken by Robert Cooke at Bredicot. The power cars are Nos.43321 and 43207 with train diagram XC804, the 1V50 06:08 service from Edinburgh to Plymouth.

From the same spot as the photograph of class 43 No.43164 (above) but nearly twenty-seven years later (on 23rd March 2011) the view was much changed with only the signals and former goods shed remaining (the latter was out of use), at least the 'HST' belies the march of time. Class 43 power car No.43310 in East Coast livery was at the head of the 06:08 Cross Country Trains service from Edinburgh to Plymouth. The train was running over ninety minutes late when it passed Bromsgrove suggesting perhaps a power car failure.

First Great Western 'HST' Nos.43143 'Stroud 700' and 43165 'Prince Michael of Kent' with the 10:22 service from London Paddington to Hereford on the single track section between Malvern Wells to Ledbury about to enter the tunnel through the Malvern Hills on 12th April 2011. Photograph taken by Andrew Smith.

The 13:23 Cross Country Trains service (No.1S55) from Plymouth to Edinburgh was normally operated in the 2010/11 timetables by a nine-car 'HST 125' set. The train is seen at Abbotswood with class 43 power cars No.43378 and 43303 in charge. Photograph taken by Andrew Smith on 27th May 2011.

HST power car No.43194 was in charge of the rarely-photographed train code No.5P94, empty coaching stock from Worcester Midland Siding to Worcester Foregate Street. Photograph taken by Andrew Smith on 29th July 2011.
