DRUMMOND 700 CLASS SOUND FIT

In 1895 it became apparent that the LSWR was in need of some 25 – 30 modern goods locomotives. At the time William Adams was still the locomotive superintendent of the London & South Western Railway but had to relinquish his position due to ill health in favour of Dugald Drummond.

Drummond whose past career had taken him from his native Scotland, to Australia and then to Glasgow brought with him not only a wealth of experience but designs of his own for the required 0-6-0 goods locomotive required for the LSWR. Drummond set about finding suitable manufacturers of the locomotive, eventually settling on Dubs & Co whose Works were based in Glasgow. Much of the locomotive’s design owed a great deal to the 0-6-0s produced for the Caledonian Railway and for which Dugald Drummond had been responsible.

Dubs & Co duly set about producing the required locomotives and from March to August, 1897 all 30 locomotives were delivered. The locomotives were numbered 687 – 716 when built however the locomotives were known as the 700 Class, however the official drawings also refer to them as “Dubs goods engines”! There were many components on this new Class that were already standard on several other LSWR locomotives, namely the C8 Class 4-4-0s, the K10 Class also a 4-4-0 and the M7 Class 0-4-4Ts.

There were initially some mechanical problems but one of the main concerns was the poor steaming.  When built the engines were fitted with conical smokebox doors and firebox spark arresters and therefore to improve the steaming the arresters were removed and new Adams pattern smokebox doors were fitted between 1902 and 1904. After this the Class were used for rather unglamorous mainline freight duties, however during the First World War they were rostered for use on secondary passenger services as well as troop trains. They could also be seen frequently handling horsebox specials and for this locomotives 687 and 700 were equipped with Westinghouse air brakes, which were removed from both locomotives by early 1936.

During the First World War it became apparent that the 700s were under boilered and to this end Drummond’s successor, Robert Urie decided after the War to fit a superheater to locomotive No. 316.  He also extended the smokebox and fitted a stovepipe chimney with a capuchin. Along with other changes to assist running, No. 316 emerged from Eastleigh Works in December 1920 and commenced running trials.  The changes proved successful and Urie was authorised to superheat 10 others of the Class. These conversions took place between March 1922 and May 1924.

After Grouping in 1923, R. E. L. Maunsell who by then had superseded Urie arranged to have the remainder of the Class fitted with his own design of superheater, which had a slightly larger heating surface.  These modifications took place between the years of 1925 and 1931 and those engines that had been superheated by Urie had their Eastleigh superheaters exchanged for the Maunsell variant between 1929 and 1933.

After these changes there were few alterations however some of the Class that ran on the Western section had chimneys fitted without capuchins.

The 700 Class engines were all initially coupled to a Drummond 3500 gallon six wheeled tenders with 13’ wheelbases, however in 1925 to 1926, 20 of the Class lost their tenders to the T9 and D15 4-4-0s which were used on the Eastern Section and the Waterloo-Portsmouth line.  These 700s received as replacements used with the K10 and L11 4-4-0 locomotives, which had a 14’ wheelbase.

After this the class virtually remained intact well into Nationalisation but by the early 1960s the Class had all but disappeared with 30697 being the last of the Class to survive the scrap yard and was steamed for the last time in January 1964.

BR 700 Class, locomotive number 30316 was outshopped from Dubs & Co, Glasgow in August 1897. During BR days the locomotive was on Shed at 71A Eastleigh from where it was withdrawn in December 1962.  In August 1963 locomotive 30316 was eventually cut up at the BR Eastleigh Works.

ZS006A User Notes for ZIMO Drummond 700 type ActiveDrive V16.02 Also suited to T9,M7,E4, H and C Class Southern 2 cyl locos.

 

 

Please spend a few moments to read these notes which have been produced so that you may obtain the maximum satisfaction from your new sound scheme.

 

The sounds should work perfectly when the decoder is fitted correctly. Individual locos may require some fine tuning that you can achieve with your DCC controller.

 

What is ActiveDrive?

 

This is a system developed to allow you, the user, to change the way that the sounds respond to your driving style or needs. This avoids the need for reprogramming and all the additional costs that would imply.

 

Operating Your ZIMO Sound Decoder.

 

As supplied, your new decoder will work in a ‘heavy train’ configuration, but you will be able to switch between the available sounds using your DCC controller by following the straightforward instructions below.

This project utilises Zimo’s ability to switch between the sounds of a heavy train load or sounds of a light engine.

These are all fully configured within the project, waiting for you to make your choice.

You can revert at any time.

 

All the CVs have been optimised but you may need to make minor adjustments to perfect it for your individual tastes.

 

There are many Functions, most of which have an individual sound attached. Some will perform a physical function (like turning on the lamps, if fitted), and some will do both (depending on equipment installed). Please study the list below.

 

Some of the sounds have a finite length and will play from start to finish when selected. Other sounds will ‘loop’ until switched off, whilst others will vary in length, depending on how you operate the F keys on your DCC controller. I’ll leave you with the pleasure of finding out which is which.

 

In any of the driving sound sets, increasing the speed step by 1 or more will produce an acceleration sound for a few seconds. If you wish continuous acceleration, ease the throttle setting upwards rather than 0- 128 in one jump!

 

Similarly, in each sound set, a reduction of 1 speed step or more will stop the exhaust beats and the loco will ‘coast’ (or drift) for a few seconds before resuming exhaust beats. Continuous drifting can be simulated by easing the throttle settings down, one step at a time.

 

All sounds may be modified (including changing or removing them) individually, and the volume levels of each one may also be varied to your own needs. For this, and much more information on your decoder’s outstanding abilities, please download the latest Decoder Manual from: www.zimo.at/web2010/

The Sound Sets

There are three sound sets loaded on your decoder.

Set 1 Heavy Loaded. This is the one to use if you have a heavy train on the hook.

Set 2 Light Engine. At very slow speeds, this set will simulate a very lightly stressed loco. This becomes more aggressive with acceleration, and as speed increases.

Set 3.Work worn locomotive with a leaking cylinder gland. (For this option, CV265 = 3)

 

 

Special Zimo Function on F5.

 

As supplied, it is possible to toggle between Set 1 and Set 2 (change from one to the other and back again) and this may be done even whilst the loco is moving, with no loss of sound. This is useful to vary the sound of the exhaust beats. But it really comes into its own when you run light loco up to a train, couple up and chug away with the heavy sounds.

All you need to do to make this happen is to press F5 on your DCC controller, and press again to change back.

 

Heavy Mode

 

This is the default setting. Inertia and momentum have high settings to reflect the high mass of a loaded train. Maximum power would be required on a real loco to lift a heavy train. This means that as well as opening the regulator, the driver would allow maximum steam into the cylinders with the reverser fully open.

 

During acceleration, the exhaust beats will bark aggressively, but the tone and volume will soften after a few seconds as the real driver would advance the steam cut-off to reduce steam entering the cylinders, increasing the efficiency of the engine.

 

Light Engine Mode

The default setting is for ‘heavy train’.

Engaging F key 5 will switch the exhaust sounds to a different set of samples, so the ‘chuffing’ is less aggressive in nature and quieter. This represents the reduced ‘cut-off’ on the reverser on real locos.

The Inertia and Momentum settings are automatically reduced when Light Engine Mode is selected. The physical characteristics are changed so the model responds more urgently to control inputs. Acceleration is more brisk and stopping distance is reduced.

Dynamic Inertia

In either Heavy or Light modes, flipping the throttle quickly to high speed steps will cause the model to accelerate 3 times more quickly from standing than if the throttle is gradually opened. This is automatic, no F keys are involved.

So now, the rate of acceleration is determined by how wide you open the regulator, just as it would on a real locomotive.

Brakes

F2 will give the sound of brake applications. F2 can be ‘dabbed’ or held for varying durations. The sound will respond accordingly.

However, if the throttle is reduced in advance, as a real driver would do, before operating the Brake Key, a braking force will be applied to the motor to slow the road speed more rapidly. This will continue to increase the longer F2 is held. Short dabs will provide speed trimming, held down continuously will result in a controlled ‘Emergency Stop’.

 

Shunt Mode

 

Inertia and momentum are reduced to zero plus speed is halved.

Shunt mode in on F Key 20

Live Volume Control

Provide the sound is switched on and the ‘fade’ button is not active, it is possible to change the overall volume to suit changing needs.

Engage F27 and the sound levels will gradually reduce, eventually to silence

Engage F28 and the sound levels will gradually increase, eventually to maximum.

In each case, disengage the F key when the desired level is attained. Set F27 and F28 as ‘momentary’ if your DCC controller allows you to do so.

Note: If the volume controls appear to not function, check that F19, F27 and F28 are disengaged before making a further attempt.

Rod Clank Volume

Many projects have heavy rod clanking included. You can change the volume of these sounds to suit your requirements.

CV286  = 160 is the project default. Higher values will increase volume, lower values will reduce volume relative to the other sounds.

Function Keys List

There are 24 Function Keys used in this sound project. Please see below.

Some of the sounds have a finite length and will play from start to finish when selected. Other sounds will ‘loop’ until switched off, whilst others will vary in length, depending on how you operate the F keys on your DCC controller.

Some keys have a control function rather than a sound.

Warnings.  Please read before fitting your new decoder.

 

1, Fit 21 pin decoders yellow component side upwards. Failures caused by fitting incorrectly , usually upside, down are not covered by warranty and will incur a repair cost to obtain a replacement decoder. Always identify the missing pin hole on the underside of the decoder and align it with the missing pin on your loco circuit board. Fitting it any other way will damage your new decoder.

2, Do not leave wire connections bare if modifying wiring to fit your installation requirements. Always use heatshrink insulation. Bare wires kill decoders.

3, On MX645 decoders the stay alive capacitor wires are the blue and grey pair on their own. Blue to the +ve (unmarked) side of capacitor and grey to grey –ve (marked -) side. Then insulate with heatshrink. Wrong way round will blow the capacitor and can damage the decoder! Do not confuse these with function blue and the motor grey wires.

4, Speaker wires, both purple, not polarity sensitive but ensure well insulated as short circuits on speaker output will blow amplifier and this is not covered on the warranty as it isn’t a manufacturing defect but considered as mishandling.

5, Please be sure you are confident working in your locomotives and have the necessary skills to fit the decoders. If not seek the services of a professional.

 

6, if attaching stay alive capacitiors to MX644D decoder use flexible wires , do not solder capacitor legs directly to the solder pads, this will result in the solder pads becoming detached fro the decoder

 

Troubeshooter  If decoder appears faulty at any time carry out a project reset setting CV8 to 0. This will restore your decoder to as shipped condition. It will also reset address to 3 again, original sounds will not be lost.
