1. Preface THE IMPETUS behind the launch of Sutton’s Locomotive Workshop (SLW) is a long-running frustration with existing model railway products. This project was initiated at a time when, in contradiction to the upward trajectory of other hobbies, models of my interest period were actually in decline – in quality, in detail, and in accuracy.
Page 4 modeller/collector and often forgotten early diesel aficionado. We have worked to a specification, not to a price, and have endeavoured to reduce the areas of compromise to a minimum. Yes, manufacturing costs have risen, but not to the degree that the big manufacturers would have you believe. It’s the profit expectation that causes the real pain your the pocket.

2. Prototype overview By way of nostalgic introduction to the prototype, no description could be better provided than by reproducing the official trade press handout that accompanied the official unveiling of the first locomotive - No. D5000 - in 1958 for formal inspection by General Sir Brian Robertson, Chairman of the British Transport Commission.
Page 6 The locomotives are of the Bo-Bo type having a designed weight in working order of 75 tons. Each locomotive is of the full width body type with a driving cab at each end. It has multiple unit equipment enabling it to operate in multiple, not only with locomotives of the same design but with all locomotives for the British Railways modernisation scheme equipped with BTH, Crompton-Parkinson or English Electric electrical equipment.
Page 7 there is no recirculation. Special care has been taken in sealing all possible sources of leakage of unfiltered air in the engine room and in this respect, the air-tight design of the radiator ducting on both sides of the panels is especially noteworthy. Bogies The bogies are of welded and riveted construction with box frames.
Page 8 Engine and Accessories The engine is the Sulzer 6LDA28, pressure-charged, six cylinder, four stroke in-line engine rated at 1,160 hp at 750 rpm with a testbed one-hour rating of 1,276 hp at 750 rpm. Five of the engines of the 30 locomotives are being supplied from Sulzer Brothers Works in Switzerland, but the majority are being built to Sulzer orders at Messrs.
Page 9 BTH Electrical Equipment Generator and Auxiliary Machines The generator unit comprises three machines – a main generator, an auxiliary generator and a differential exciter. The main generator is a single-bearing, 12-pole, separately-excited, self-ventilated machine solidly coupled to the diesel engine and mounted on an extension of the engine underbed.
Page 10 excitation being proportioned so that there is a definite maximum limit to the current which can be delivered to the traction circuit at standstill, and so that at this point, the demand on the engine is less than its rated output. The section of the characteristic which intersects the contact HP curve of the engine is artificially controlled by varying the separate field of the exciter by means of a rheostat.

Spotting features driver’s controller to ‘off ’ but a flag on the relay remains displaced until reset by hand, thus indicating to the shed staff that an earth fault has occurred at some time during service.

Dependent on period/livery, the models either display High-level air pipes the original resonator silencer with its raised, curved surface and circular exhaust In 1964, the Tyne Dock-Consett iron ore trains were taken over by Type 2s working port, or a later plated-over roof section and simplified direct outlet.

There should be no need to access the interior of the model in normal use. Access to the chassis, motor and printed circuit board is gained by removing the bodyshell. There are four small securing lugs moulded on the inside of the bodyshell, positioned above the inner axles on both sides.

The first of these is the In another first for a British model, and in response to the demands of those using provision of two energy storage capacitors wired in parallel.
Page 17: Digital Sound Operation
10. Digital sound operation Sound specification The model is fitted with a ZIMO MX645 PluX22e DCC sound decoder, tuned to a Introduction pair of high-end miniature 8Ω loudspeakers housed in custom-designed plastic Installing sound into a model locomotive significantly increases its cost. We believe enclosures mounted within the die-cast chassis.
Page 18 How a real locomotive operates To simulate the sounds of a diesel-electric locomotive successfully, you will need some idea of how and why they sound as they do. The most important aspect to know is that the diesel engine itself does not propel the loco directly. The engine drives a generator, which provides the electrical power for the traction motors.
Page 19 change your DCC driving technique but has the feeling of ‘putting you straight in Special control features the driver’s seat’! Here’s how it works: We have included several special control features which you may use to modify the For optimum control and convenience, the feature needs to be assigned to a way the sound samples play.

With this single Light engine mode: Characteristics of an uncoupled or ‘light’ locomotive will be action you can dramatically affect the engine sounds being played. It will produce quite different from when it is has a heavy train in tow. It will be capable of accelerating different effects depending upon the speed of the loco, including when it is stationary.
