About the SMR 10 Class

The South Maitland Railways 10 Class locomotive is a class of coal-fired, 2-8-2 Tank Steam Locomotives with a total of 14 units built for the East Greta Coal Company (later South Maitland Railway in 1918) by Beyer, Peacock and Company in Manchester, England, between 1911 and 1925. The East Greta Coal Company had constructed its railway empire based on secondhand and borrowed steam locomotives, which by 1910, was fast becoming insufficient to move the great loads coming from the Greta Seam which ran right through the South Maitland coalfield so a new form of motive power was needed and so the 10 class was it's choice.

The locomotives were delivered in knocked down form, and assembled onsite at the East Greta Junction Workshops (also known as the 'Red Shed').

In 1911 the first 4 locomotives were delivered into service with another 10 built between 1920 to 1925. The fourteen locomotives were numbered where they could be accommodated within the East Greta Coal Company numbering system and as a result they were numbered as follows 10, 17-20, 22-28 and 30-31.

The SMR 10 class were primarily used to haul coal trains and this remained consistent until the 1950s, when a sharp downturn in demand for coal led to certain members of the class being set aside leaving only 18,20,23,25,30 and 31 in service. With an upturn in the late 1960s, and the purchase by Coal & Allied (C&A) in 1967 of Hebburn Limited which gave C&A 100% ownership of South Maitland Railways. It was decided to start repairing the 10 Class as soon as possible for the revived traffic t them all back into service.

Steam on the South Maitland Railway system ended in June 1983, with 31 bringing in the last load of coal and all but four of the 10 Class were withdrawn from service with the remaining four being withdrawn in 1987. All 14 members of the 10 Class have been preserved.

DCC with Sound Installation

The Southern Rail Models 10 Class Tank Locomotive was released in October 2017 as a DC/DCC Ready model which includes an 21 pin socket and speaker. The model also has operating Headlights & Marker Lights

Sound version were also released with an ESU LokSound SELECT OEM Sound decoder which has it's limitations compared to the full featured LokSound V4.0 or SELECT sound decoders

Latest Update - April 2018:

Shorting issue running through points (Turnouts).

For months now we have been installing sound into these models and until now have found no running issues during our testing on Peco Code 100 track and insulated points (Turnouts)

However during recent extensive testing on Peco Code 83 track, the model causes a short when running through insulated points, thus shutting down the DCC System. Our investigation of this problem has revealed that the extremely wide flange-less centre wheels bridge the small gap between the rails at the frog of the point resulting in a visible spark from the short causing a system shutdown.

This led us back to more extensive testing on Peco Code 100 track and to our astonishment the model actually causes the same spark when running through Peco Code 100 points. So why have we not discovered this previously, well the short circuit protection device that is installed on our testing layout reads it as a low level short and allows the DCC system not to shut down as the protection device handles the short. When we turned the short circuit device off, the model caused a DCC system shut down when running through the Code 100 point.

An issue like this should have been sorted out during pre-production testing and now that the model is released there is nothing that can be done to the model to rectify this problem. A solution to those running this model that maybe causing this problem would be to apply some clear nail polish, liquid electrical tape or some clear stick tape over the section of track rail either side of the frog.

For DCC installations our preferred decoder is the ESU LokSound V4.0 (Sound) with our Custom 10 Class Sound project.

For those not interested in sound the LokPilot V4.0 (No Sound).

Alternate decoders: ESU LokSound Select, TCS WOW Steam sound, the Soundtraxx Econami or the new Tsunami 2 Sound Decoders.

The DCC Solutions Custom SMR 10 Class Sound Project

for the ESU LokSound V4.0 is packed with more sounds and features, compared to OEM Sound from the manufacturers,

to have your model sounding just like a real steam locomotive.

Our SMR 10 Class Custom Sound Project now includes some new features:

Remastered Sound Project

Our 10 Class Steam Sound Project has been remastered and includes some new recorded sounds and features to make it stand out from the rest.

Now with a Cold Boiler Start Up Sequence including boiler water fill and fire up sequence before moving off or an optional Quick Hot Boiler Start Up Sequence which goes straight to waiting for the correct boiler pressure to be reached before moving off.

The drive sounds will increase and decrease gradually with speed. When you suddenly decrease or increase the throttle by at least 10 speed steps quickly while driving you will hear the sounds of the steam locomotive working. After a set amount of time or by increasing the speed, the locomotive will return back to normal running.

Full Throttle - Heavy Load

This feature allows you to simulate a loaded, hard working steam locomotive by pressing the F1 function button. When the button is pressed, the motor will remain at a constant speed, while the sound can be controlled independently by adjusting the speed on the throttle allowing for a fierce full chuff or drifting with rod clanks. Release the Heavy Load function button and you simply go back to throttle-controlled speed and motion

Coasting on Demand

Coasting on demand can be used to suit your running environment allowing variable speed coasting so changes in speed will not turn it off until you turn it off.The loco will enter the coasting mode and remain in coasting regardless of changes in the speed. Experiment with turning it on and off while the locomotive is moving at speed to hear the sound changes of a steam locomotive.


Press the Brake Function button and your loco will come to a stop at a much shorter distance than if you were to bring the loco to a stop by reducing the speed throttle. Press the function button to release the brake and your loco will move off again or set the speed throttle to zero when stopped and release the brake for the locomotive to remain stationary.

Random Sounds

New random stop and drive sounds have been added to increase the realism of your model.

Coupling with Auto Shunting Mode.

Press F14 and Shunting Mode activates to automatically reduce the loco speed then press F14 again when ready to couple up to hear the coupler clash. Shunting mode will remain on for a few more seconds then will switch off returning you to normal throttle speed control. Repeat this same procedure to hear the uncoupling sounds.

New Headlight Operation (Models with Headlights Fitted)

We have also modified the headlight operation to resemble prototypical operation.

In the past you would have turned off the sound (Pressing F8) and all the sounds including the generator would stop playing but your headlight would remain on and you would have to turn it off separately. Well no more...

Press the headlight button (F0) to turn on the generator. The headlight won't turn on until enough power has been generated to turn the light on dimmed and bright while driving. While the generator is on the headlight stays on. If you press F8 to shut down and turn the locomotive sound off this will include the generator so then the headlight will also turn off even if you haven't turned the headlight off itself using the headlight button.

Also added are:

  • High Beam Headlight Function allowing you switch the headlight between high beam and low beam while driving when required during NSW Steam Locomotive Operations.
  • Low Beam Headlight is also available when reversing.

And includes all these great features not found on other sound decoders to make your SMR 10 Class drive and sound impressive.

  • Cold Boiler Start Up Sequence including boiler water fill, fire up sequence, boiler pressure reached before moving off.
  • Optional Quick Hot Start Up Sequence - Straight to waiting for boiler pressure to be reach before moving off.
  • Playable Whistle with varying starting and ending sequences.
  • Short Blast Whistle including 3 toots for reversing.
  • Fast/Slow air compressor
  • Playable stationary boiler/steam sounds including additional random sounds.
  • Shunting mode for slow speed shunting operations.
  • Driving and Coast on Demand allows you to drive your model like a real steam locomotive.
  • Working Brake
  • Random Drive Sounds including track squeal, compressor, injectors, coal shoveling, and more.
  • Random Stop Sounds including compressor, injectors, blower, steam releases, coal shoveling and more.
  • Generator controlled Headlight. The headlight is controlled by the generator sound (Optional)
  • High Beam Headlight Function allowing you switch the headlight from high beam to low beam and back while driving. (Optional)
  • Optional low beam headlight when reversing. (Optional)
  • Individual Coupling and Release Options depending on the locomotive's direction with automatic activated shunting speed mode.
  • Tank water filling sounds.
  • When the loco stops after braking the compressor cuts in to fill the reservoir .
  • Motor settings and sound volumes tuned to specifically suit the Southern Rail Models 10 Class Locomotive Model.
  • Slow Speed Motor settings for improved performance
  • Sound control and volumes can be adjusted by the user to suit personal running requirements.
  • Full 28 function button remapping to suit your personal requirements.
