Coaches built by the LMS
The design and building of LMS coaches followed a very standardised pattern. Very many types of coaches were built to suit the various services and needs but, in general, the progression of design features was a logical one. Three quite distinct periods of design can be recognised, [2] the last of which continued until after nationalisation of the railways in Britain.
Period I (1923–1928/9)
The general styling of LMS Period I coaches followed much the same ideas as were prevalent elsewhere in Britain. They were wooden framed and panelled, had a fully beaded body with a semi-elliptical roof, doors to all compartments of side-corridor coaches, and were mounted on a steel underframe derived from the final Midland Railway design. Window ventilation was mainly by droplight. Roof ventilators were generally of the torpedo type. The coaches were fitted with non-automatic screw couplers and gangwayed stock made use of scissors-type British Standard pattern corridor connection (as also used on the Great Western Railway).
Most coaches ran on two four-wheel bogies which were of a 9 ft 0 in wheelbase single bolster design which hardly changed for the whole of the company's life. Some special vehicles ran on twelve wheel chassis and the six-wheel bogie on these vehicles was of 12 ft 6 in wheel-base, based on the London and North Western Railway design. All coaches except kitchen cars were electrically lit and normally fitted with vacuum brake as standard.
Certain characteristic Midland Railway features were incorporated in the design of early LMS coaches which distinguished them from those of other lines. Most noticeable of these was the twin-window arrangement in each seating bay of the vestibule coaches. This took the form of two rectangular windows side by side (one fixed and one drop-light), rather than a single window or centre drop-light with two flanking quarterlight arrangement. There was generally a Stones pattern ventilator in the eaves panel above the fixed light of these window pairs.
During this period, the LMS company introduced a considerable quantity of conventional coaches which were comfortable and well built but whose designs were not particularly revolutionary. Externally, these early LMS coaches were extremely attractive in the fully panelled and beaded style and with the fully lined Crimson Lake livery.
The first indication of changing ideas were some very handsome corridor vehicles in 1927. For the first time, the LMS abandoned outside compartment doors in corridor coaches and introduced larger windows in their stead. At first there were two such windows in each compartment (one fixed and one frameless droplight) in the manner of the characteristic Midland pattern vestibule coaches already considered. They differed from the normal twin-window style in having frameless droplights and Stones ventilators over both windows and the style soon became adopted for other vehicles. By 1930 it had made its appearance in some composites, this time with but one Stones ventilator centrally over the window pair and with large 4 ft 6 in wide corridor side windows.
The next development in the somewhat tentative progression towards more up to date amenity was the development of a single window per bay design which was introduced in 1928 with the building of ten very palatial carriages for inclusion in the Royal Scot and other prestige trains. Five of these coaches were semi-open firsts that had three compartments all finished in a different style with only four seats in each; each passenger thus had a corner seat. The open end was rather more conventional, seating 18 in two-and-one arrangement. These coaches were classed as dining vehicles and generally ran next to a kitchen car. The other five coaches were equally luxurious lounge brakes with accommodation for 10 first class passengers in eight individual armchairs and a settee. They again had large single windows instead of the two-window arrangement.
These 10 vehicles were followed in 1929 by a similarly styled batch of 25 neutral vestibule coaches for either first or third class passengers. These were 42 seaters with seven bays arranged two and one and again designated as dining vehicles. With these, the single window style could finally be said to have 'arrived' in LMS gangwayed coaches.
Although these 1928–29 coaches had single windows, they were still of the high-waisted design with full exterior beading - as indeed were most LMS coaches to this time - and there is some evidence that although the single window was more appreciated than the earlier arrangement, it was not always easy to see out of it because of the high waist. This was, apparently, particularly irksome in the lounge brakes which with their very low seated chairs were, seemingly, never very popular. Thus it was that the single window design was not perpetuated in the high waisted style.
Some all-steel coaches were introduced in 1925–26. These were open thirds and brake thirds, together with a large number of full brakes, which were built by outside contractors, probably to assist the steel industry at that time. Construction apart, however, their two-window style and interior layout showed no advance on the other coaches of the time while externally they were finished in a pseudo fully beaded style.
Period II (1929–1932)
The start of the second phase in LMS carriage design was almost contemporary with the introduction of the previously mentioned high-waisted, single window designs and the new trend of thought was first exemplified by the appearance in 1929 of six luxury brake firsts with two-a-side compartment seating and somewhat palatial toilet accommodation.
These new carriages all had single windows but the waist of the coach was much lower than hitherto. The principal external difference was the elimination of the waist panel as result of deepening of windows. The new coaches were, however, still wood panelled and fully beaded and with the full lining represented very handsome designs. As with their Period I predecessors, these coaches went to the more important trains such as the Royal Scot.
This low waisted trend in design only partially set the pattern for new construction because corridor composites continued to come out in the fully beaded two-window style and the corridor thirds and brake thirds continued to have full compartment doors until 1930. Thus there was a certain amount of overlapping styles during the first part of the second period of LMS coach building.
It was again the vestibule coach which received the bulk of attention during this second phase. The first were a series of spacious 60 feet (18 m) long 42 seaters. Some of these, which were classified as dining vehicles were built as firsts but were downgraded a few years later on the advent of the Stanier 65 feet (20 m) firsts. They were followed by a 56 seater for general service. More 42 seat coaches followed which, although identical to the original 42 seaters, were not classed as diners. All these 60 feet (18 m) coaches had the new low waist and were wood panelled with full outside beading. However, a much larger group of low-waisted vestibule coaches was the 57 feet (17 m), 56 seat version of which 300 were built in 1931-2 and differed from the 60 feet (18 m) version in that they were steel clad with simulated external beading in paint. They did, however, follow the Period II style in all other respects and retained the raised window edge mouldings.
Eventually in 1930–31, the new low waisted style was adopted for all corridor stock too. Although mainly confined to composites and brake composites, it was a batch of corridor thirds in 1930 that really set new standards. These coaches were but 10 in number but had only seven compartments on a 60 feet (18 m) underframe. Although the traditional four on each side seating was retained, the compartments were no less than 6 ft 6 in between partitions. They were again wood panelled and fully beaded and were, reputedly, extremely comfortable. However, no more were built possibly because they were a little extravagant of space and large numbers of the earlier designs had been built between 1924 and 1928. They were to be the only corridor thirds to be built to this length.
On the specialised coaching side, this second phase of design was represented mainly by dining cars of which 36 were built which made amends for the relative lack of new dining cars during the first six years of the LMS. Like the 57 ft vestibule thirds mentioned earlier, these diners were steel panelled with painted simulated beading.
There were also two batches of 12-wheel composite sleeping cars built at this time that retained a high waist and certain LNWR styling features but were flush clad with frameless droplights. They were distinctly outside the main trend of LMS coach design.
Period 2 non-corridor stock differed little from the Period 1 examples.
Period III (1933 onwards)
In 1932, William Stanier took up his appointment as Chief Mechanical Engineer to the LMS and the first of the completely flush sided LMS coaches emerged soon enough after his assumption of office to lead to the coaches ever afterwards being referred to as "Stanier" stock.
The LMS flush sided coach, of which many examples still remained as late as 1967–8, differed in appearance from its predecessors mainly in the shape of its windows which now exhibited well-rounded corners. All the earlier coaches had, of course, been built with slightly rounded window corner mouldings but by comparison with Stanier vehicles, the Period I and II coach window was almost square cornered. The second major visible difference was also in the window area. During Period I, the favoured method of admitting fresh air was the droplight which was frequently supplemented by and finally (in Period II) in large measure superseded by the Stones and Dewel pattern glass vane ventilator.
With the Stanier stock was introduced the now familiar sliding ventilator incorporated in the upper part of the window. Initially this was quite shallow with only one section moveable but in 1934 this was replaced by a deeper ventilator with two wide sliding sections which remained almost until the end. From about 1947–8, the sliding portions were somewhat shortened and in this form were retained as a feature of the British Railways (BR) standard coach.
During the Stanier period, non-corridor coaches varied little from the pattern laid down in the 1920s except for the flush clad exterior. The design was still high waisted and the seating arrangements never changed from the earlier years. No inter district lavatory sets were built during the Stanier regime and apart from a few lavatory composites for the London Tilbury and Southend section, all the Stanier non-corridor stock was of the suburban type. There was an interesting batch of articulated triplets made in 1938 but these do not seem to have been very popular.
