Southern Pacific Diesel

SR Leader class - 12PSB Test Bench - CP-60 Current Probe manufacturer

Background The basis of the Leader originated from a 1944 review of the Southern Railway's steam locomotive fleet, resulting in a Southern Railway design brief which called for a high-powered locomotive requiring little maintenance to replace the ageing fleet of M7 class tank engines.

The brief also stipulated that the locomotive would be used on both passenger and freight trains, requiring high route availability. Bulleid proposed an initial design based on his SR Q1 class locomotive, which had proved easy to maintain in service. As the proposal progressed, Bulleid saw that certain tasks required with conventional steam locomotives could be eliminated by adopting some of the features of the contemporary Southern electric locomotives. However, one of the subsequent designs of a 0-4-4-0 wheel arrangement had an unacceptably high axle-loading of 20 tons (20.4 tonnes), which increased the risk of damaging the Southern Railway's track. By developing the proposal further, Bulleid settled for a 0-6-6-0 design of bogied locomotive, which spread the weight more evenly over the rails and reduced the axle-loading. Design Works diagram of the Leader A series of initial ideas were presented to the Southern Railway management by Bulleid that incorporated double-ended running, giving the locomotive driver maximum visibility in either direction without a boiler or tender obscuring his view.

The need for a turntable to turn the locomotive around was therefore eliminated, although the initial designs were rejected by the operating department because of problems with welding technique. The accepted design included two 0-6-0 steam bogies with weight-saving sleeve valves and chains to couple the driving axles, as used on Bulleid's Pacifics. The boiler was offset to provide space for a communication corridor, allowing the driver to access both cabs without leaving the locomotive, an arrangement which led to later problems. The firebox, near the centre of the locomotive, was fed by the fireman from a third cab, linked to both driving cabs by the communication corridor. The entire ensemble was placed on a common frame, and thus often referred to as an 0-6-6-0 tank engine). The Leader prototype was constructed at Brighton railway works, and work began in 1946. An initial order of five locomotives was placed straight from the drawing board in 1946, and a further 31 were ordered in 1947, although with nationalisation looming this was merely a gesture. The latter order was cancelled after Southern Railway was taken into public ownership, to allow trials to be carried out on the prototype. Bogie and cylinder design Each of the two bogies had three cylinders, with the driving wheels connected by chains enclosed in an oil-bath, based upon Bulleid's chain-driven valve gear on his Pacific locomotives. The valve gear used the unusual sleeve valve arrangement that was also tested on the ex-LB&SCR H1 class Hartland Point in parallel with the construction of the first Leader locomotive.

The Leader was the first steam locomotive to use a form of sleeve valve since Cecil Paget's locomotive of 1908, and the concurrent testing of the principle on Hartland Point hints at the rushed nature of the locomotive's conception. The locomotive sat on the unusual Bulleid-Firth-Brown wheels, which were lighter, yet stronger, than the spoked equivalent. The use of sleeve valves and oil baths to lubricate the moving parts of the engine units was inspired by contemporary internal combustion engine practice. This included oscillating gear that gave a 25-degree axial movement to the sleeves, allowing even lubrication of the moving parts. However, this resulted in an over-complicated mechanism that was difficult to maintain, perpetuating the seizures it was meant to eradicate. This feature was removed from both bogies of the prototype as the trials progressed. Another innovative feature of the steam bogie assembly was the ability to interchange them when faults occurred, an easy operation for maintenance staff when compared to the complexities of overhauling a regular steam locomotive's motion. The three cylinders of each bogie were cast in mono-block format, each surrounded by two annular inlet steam chests and a single large outlet steam chest. These had the added function of keeping the cylinder heated by hot steam to maintain the temperature and pressure of steam entering the cylinders. However, these castings were difficult to machine accurately. The steam-sealing arrangements needed for this system were also complex, with each of the six cylinders and valve sleeves requiring 24 sealing rings. Boiler, firebox, smokebox and casing design The Leader boiler and firebox, showing the offset firehole door position (dotted). Also visible are two of the four thermic siphons The boiler was the culmination of lessons learned with the Pacifics, and was a prolific steam-raiser. All Leader boilers were constructed at Eastleigh, and proved to be the least problematic area of the entire design.

 

The boiler pressure was set at (280 psi (1.93 MPa)), and each was fitted with four thermic siphons from beneath the firebox to pre-heat water entering the boiler, used to great effect on Bulleid's Merchant Navy, West Country and Battle of Britain classes. The Leader had a "dry lining" firebox; it was not surrounded on top and sides by a "jacket" of water as in normal practice. It was constructed of welded steel, and used firebricks instead of water for insulation, which was a novel but troublesome solution to dry-lining the firebox. These had the effect of reducing the grate area from 47 square feet (4.4 m2) to 25.5 square feet (2.37 m2), and concentrated the fire in a small area. The firehole door was offset to the left of the boiler backhead, and was to provide difficulty for the fireman to add coal to the fire. The firebox was not initially equipped with a firebrick arch, although one was retro-fitted during the summer of 1950. The arch was problematic as it promoted the tendency for flames to enter the cab at high outputs, a situation made worse by the narrowing of the firebox area. The smokebox had an inherent problem in maintaining a constant vacuum. This was a result of another Bulleid labour-saving innovation, a sliding hatch controlled from the front cab that enabled ash to be cleaned out through a chute onto the track when on the move. The problem lay with ash manifesting itself around the edges of the slide, allowing air to leak into the smokebox, therefore reducing the overall efficiency of the locomotive. The fierce blast from the exhaust also meant that ash and embers were ejected into the atmosphere, creating a potential lineside fire hazard.

For ease of maintenance the boiler, firebox, smokebox and tender were encased in steel sheeting that resembled a modern diesel locomotive, a major departure from traditional steam locomotive design, allowing the engine to be cleaned using a carriage-washing plant. The tender was designed to carry 4 tons (4.06 tonnes) of coal and 4,000 imperial gallons (18,000 l; 4,800 US gal) of water, and was covered by a tarpaulin to prevent water ingress into the fireman's cab. Entry into the locomotive was by way of ladders leading up to sliding doors, although due to the bogie design, the climb into the fireman's cab necessitated clambering over the oilbath casing. Construction Construction of the first five Leader locomotives began at the Southern Railway's Brighton railway works in July 1947. British Railways inherited the Leader project upon nationalisation in 1948, which was far enough advanced to continue constructing the prototype, as Bulleid was still Chief Mechanical Engineer of the newly formed Southern Region of British Railways. Although work on the other four locomotives stalled, the prototype Leader emerged from Brighton as locomotive No. 36001 in June 1949. The other four members of the initial order made by the Southern Railway, Nos. 360025, were at varying stages of construction by the end of the development period. No. 36002 was almost complete, No. 36003 was without its outer casing, and Nos. 360045 were little more than sets of frames, although most of their major components had been constructed at Eastleigh and Brighton and were stored ready for fitting. With no prospect of further money being allocated by the Railway Executive for their completion, the unfinished locomotives were put into store at various depots around the former Southern Railway network pending a decision on their future. Operational details No. 36001 was immediately put into service trials using empty passenger carriage stock in the south-east of England. The official trial records kept at Brighton works reported varying degrees of success and failure on the runs undertaken. However, the results of the trials as reported to British Railways headquarters at Marylebone were "conspicuous by the absence of praise" for the strengths of the Leader, namely the boiler, braking system and total adhesion provided by the two bogies. Several theories have been put forward regarding this state of affairs, the most plausible being that the more conservative members of the railway workforce at Brighton and the Railway Executive felt that the Leader was too revolutionary, and were keen to maintain the status quo. Performance of No. 36001 The Leader being lifted onto its power bogies at Brighton, May 1949. The casing allowed the locomotive to be put through a carriage-washing plant Following trials that lasted over a year, No. 36001 was shown to have several flaws, including heavy coal and water consumption, mechanical unreliability, untenable working conditions for both fireman and driver, loss of steam through the cylinder rings and uneven weight distribution on the bogies.

After renewing the cylinder assembly, it was tested around Brighton and Eastleigh using an LNER Dynamometer car, where good running was experienced at high costs in fuel and effort on the part of the fireman. The Leader was tested against the performance of a U class control locomotive, and indicated that the brake release was too slow in service for use on tight schedules despite the brake application being noted as the best used on a Bulleid design. Throughout No. 36001's trials the firebrick lining provided a constant problem by continually collapsing into the fire. The firebricks were then replaced with cast iron substitutes that melted in the intense heat of the firebox, which were in turn replaced by thicker 9 inches (23 cm) firebricks. Some of the firemen allotted to the Leader complained about cramped conditions in the centre cab of the locomotive, a situation made worse by flames entering the cab from the firebox at high outputs. It was an enclosed space that was constantly hot, and the single fireman's entrance door on the side of the locomotive was left open during travel to promote ventilation. The door into the fireman's cab also attracted criticism, as it would have been blocked in the event of the locomotive overturning on that side, preventing the fireman's escape, so that members of the railway trade union ASLEF threatened to stop their crews from operating the Leader. The offset boiler and tender caused the locomotive's centre of gravity to be shifted to one side. Experiments had to be undertaken to balance the locomotive by filling the linking corridor with large quantities of scrap metal, replaced in a re-design by a raised floor covering weighted material. These modifications resulted in the engine exceeding the total weight limit of 150 tons (151 tonnes), severely limiting the design's route availability during testing. A related problem was that despite being a tall locomotive, at 12 feet 11 inches (3.94 m), the cab ceilings were relatively low.

The cab at the smokebox end of the locomotive suffered from the same excessive heat as did the fireman's cab. To circumvent this problem the locomotive was used in reverse, as the rear cab was next to the water tank and coal chute, and therefore away from the hot gases circulating inside the smokebox. Despite its problems the locomotive displayed outstanding steaming characteristics and total traction from the two power bogies on its trial runs. When properly fired the Leader was capable of keeping up with the schedules, even running ahead on occasions. However, operational difficulties when stopping for water tended to lose any time advantages gained, and affected the published performance figures. Despite hauling test trains over the Central Section of the former Southern Railway, the Leader prototype was never used on a revenue-earning service because of the risk of failure of the valve gear, and the adverse publicity this would cause for British Railways. Livery and numbering Southern Railway When the project was under the auspices of the Southern Railway, No. 36001 would have been numbered CC101. Bulleid advocated a continental style of locomotive nomenclature, based upon his experiences at the French branch of Westinghouse Electric before the First World War, and those of his tenure in the rail operating department during that conflict. The Southern Railway number followed an adaptation of the UIC classification system where "C" refers to the number of driving axles in this case three on each bogie. Since the design has six driving axles, the numbering would have been CC101C105 with the initial batch, the final number being the locomotive identifier. British Railways Operational livery was ex-works photographic grey with red and white lining. The British Railways "Cycling Lion" crest was also used, though after the works photograph this was painted over without explanation. Numbering was the British Railways standard system, in the 36001 series. If the class had gone into full production, the locomotives would have been painted in British Railways mixed traffic/freight black livery with red, grey and cream lining. 36001 was initially painted in this livery, but this preceded the official works photograph and was subsequently repainted in photographic grey livery. Operational assessment Despite the high expectations attached to the Leader, it was not the motive power revolution that Bulleid intended it to be. No part of the Leader design was perpetuated on the British Railways Standard class locomotives by Robert Riddles, nor did it find favour internationally, with the Garratt articulated locomotives providing a similar function for less maintenance.

The whole concept was quietly dropped in 1951 after Bulleid left British Railways to become Chief Mechanical Engineer of Cras Iompair ireann (where he produced CI No. CC1, a peat-burning locomotive to a similar design), and all five were scrapped. The culmination of the project was a 178,865 5s 0d (4,074,550.40 in today's money, converted at the 1950 rate) bill for the taxpayer, though when the press reported the story as late as 1953, 500,000 (11,390,000.00) was claimed to have been wasted on the project. R. G. Jarvis, who was placed in charge of the project after Bulleid's departure, insisted that the locomotive required an entire re-design to solve the problems of the original concept. No members of the Leader class survived the 1950s, and only the numberplates of No. 36001 and No. 36002 are known to exist. The numberplate for No. 36001 is located in the National Railway Museum, although a locomotive builder's plate intended for the locomotive, but never fitted in service, was sold at auction in 2008. The Leader was a bold attempt at pushing back the boundaries of contemporary steam locomotive design, and if successful, would have prolonged the life of steam on Britain's Railways.

Southern Pacific Railroad (SP) locomotive number 9010 is a KM ML 4000 CC dieselhydraulic locomotive, built in 1964 by German manufacturer KraussMaffei (currently supplying locomotives as Siemens Transportation Systems). SP 9010 generated 4,000 horsepower (3,000 kW) from two 2,000 horsepower (1,500 kW) V16 Maybach MD870 diesel engines. It was painted in the 1958 socalled bloody nose colors of Scarlet and Lark Dark Gray for its entire operating career. It was renumbered to SP 9113 in late 1965, rebuilt extensively at SPs Sacramento General Shops (later Sacramento Locomotive Works) during the latter half of 1966, and was initially retired in 1968. It was revived and rebuilt by Sacramento General Shops into a camera car for the purpose of shooting motion picture background plates for a groundbased locomotive training simulator.

High Quality Content by WIKIPEDIA articles The Southern Pacific Transportation Company (reporting mark SP), earlier Southern Pacific Railroad (18651885) and Southern Pacific Company (18851969), and usually simply called the Southern Pacific, was an American railroad. The railroad was founded as a land holding company in 1865, later acquiring the Central Pacific Railroad by lease. By 1900, the Southern Pacific Company had grown into a major railroad system which incorporated many smaller companies, such as the Texas and New Orleans Railroad and Morgans Louisiana and Texas Railroad, and which extended from New Orleans through Texas to El Paso, across New Mexico and through Tucson, to Los Angeles, throughout most of California including San Francisco and Sacramento.
