INSTRUCTION MANUAL
“DECAUVILLE 0-4-0T”

Page 2
Safety first
All our locomotives are safe to run, and will give many hours of pleasure,
providing the following safety procedures are followed:
1. Please read the instructions thoroughly before running fort he first
time.
2. Always do a complete refill of gas, oil and water. Never refill just
the gas to prolong the run.
3. Never let the engine run out of water.
4. When refilling the gas, do not have any naked flame present, and
NO SMOKING!
5. Do not pickup the engine by the bodywork, chimney or boiler,
especially when hot.
6. Only pick up the engine by the buffer beams and, when hot, use
old cloves or a cloth.
7. Do not stand over the chimney. Ejected boiling water or steam may
cause serious injury.
8. Do not open the smoke box door while the engine is alight.
9. If the locomotive gets slower and finally stops the gas is all. Please
close the gas and steam regulator.
10. If the locomotive comes to an aprupt halt, the water is all. Please
close immediatly the gas supply, otherwise you will risk a boiler
overheating.
11. This live steam model is not a toy and does not belong in reach of
children under 14 years. Adults should exercise particular caution
in steam-operation in the presence of children.
Generell Hints
As with all operating machinery, whether model or full size, wear will
occur. In the model steam locomotive much can be done help prolong its
life and decrease the amount of time required in the workshop for
servicing.
Keep the engine as clean as possible, and the motion free from dirt and
garden debris. The valve gear, axles and crank pins should be oiled
sparingly with light oil, e.g. our special lubrication oil. Over-oiling attracts
dirt and grit, which will increase wear.
Regularly check that all screws and motion bolts are firm. Do not over-
tighten, as this strips threads and shares bolts.

When filling the lubricator, always use a high temperate steam oil; this is
available from us or other retailers. Failure to use the correct grade of oil
can lead to blocked steam pipes, and will invalidate the guarantee.
When running your engine avoid excessive speed and acceleration, both
will cause premature wear in the valve gear. Prototypically, narrow
gauge locomotives ran at speed of between 10 and 20 M.P.H. and never
exceeded 25 M.P.H.
Positions of Fillers and Drains etc.
The cab roof lifts up and tilts to the right hand side to give access to all
fillers.
The gas inlet valve is in front near side corner of the cab, at the top of the
gas tank turret. The gas control valve is attached to this turret, and can
be operated through the nearside cab doorway or open backside.
The lubricator is in the offside front of the cab, just forward of the
doorway and reverse lever. The filler cap has a “T” bar in it to aid
removal. The lubricator drain is directly beneath the lubricator. To drain,
open the ball valve downwards.
The boiler water filler is on top of the steam turret on the boiler in the
middle of the cab. Undo the knurled cap to fill with water.
The main steam regulator valve is located on the rear of the boiler-filling
turret and can be controlled through to open backside of the cab.
The water gauge is on the backside of the boiler in the middle of the cab
near the burner.
The boiler blow down valve is under the footplate, just in front of the
nearside cab. To open it, turn the ball valve downwards.
The direction control is the lever in the offside cab door. To operate pull
gently outwards and move to the desired direction. The control is “gated”,
and will therefore hold itself in the full forward or reverse position.

Preparation for running
The Decauville is fitted with a water gauge; this allows the driver to keep
the model in steam continuosly for longer periods of time than the usual
single fill system. This is done using a boiler Top-up System avaiable
from us or your dealer. The initial fill up with gas, oil and water is the
same as for a basic run, but then to carry on and run for longer periods
requires supervision of the boiler water level, topping up of the lubricator
and refilling of the gas. These procedures will be explained in another
section after the Running section instructions.
Always service the engine in the following order; first gas, oil then water.
To fill the gas tank: invert the gas can and apply the nipple to the gas
inlet valve on the top of the tank turret. It is advisable to support the loco
under the gas tank whilst filling, to prevent the engine tipping over. You
will know when the tank is full; gas will blow back from the inlet valve in a
strong jet. A small amount of gas and air will escape during filling, but the
difference between this and when the gas tank is full is always clear.
Always keep the gas can vertical when filling the gas tank.

Page 5
Filling the lubricator: as you will read in the instructions fort he end of the
run, the lubricator should be empty of oil and water with the valve left in
open position. Now close the valve and remove the lubricator filler cap.
Fill up the lubricator with steam oil to about ¼ of an inch (about 1 cm)
below the top. Leave the filler cap off for the present, so that any tapped
air can escape. It can be refitted after you have filled up the boiler.
To fill the boiler: remove the filler cap and also open the water check
valve. Leave the boiler blow down valve open whilst raising steam.
Fill up the boiler completely – ideally use filtered rainwater or distilled
water using the large syringe provided. Replace the boiler filler cap,
check that the lubricator does not need topping up, and then replace its
filler cap also Filler caps should be firm tight. They are sealed with a
trapped “O” ring and, therefore should no be over-tightened.

Lighting Up
Open the smokebox door; just pull it open by the door handle. Light your
lighter/match etc. and gently open the gas control valve until a gentle
hiss is heard in the burner.
Apply your light into the smokebox and the flame should “pop” down the
fire tube and ignite the burner inside the fire tube.
If the gas valve is open too much the flame will not pop back; it will either
fail to ignite, will roar in flame out of the smokebox, or there will be a ball
of flame around the front of the engine, which will then blow the whole
fire out (after giving the driver a fright)!
When the fire sound has stabilised, after about 30 seconds the gas can
be turned up until a healthy roar is heard. The smoke box door may be
shut after about two minutes. Now leave the locomotive to raise steam.
When the pressure starts to rise, water will be seen running out of the
boiler blow down valve. When the water reaches its correct level steam
will be seen. Now close the check valve and let the locomotive raise at
least 40 p.s.i..
Running
When the engine has raised about 40 p.s.i. you are ready to start
running. It is advisable to run the engine in reverse first; it clears the
condensed water from the cylinders best this way. Before commencing
your first run of the day, it is advisable to put a cloth loosely over the
chimney for a few minutes, as condensed water will be ejected from the
chimney. This is quite normal; the motion of the engine will be jerky until
all condensate has been ejected. Do not stand over the chimney as
ejected boiling water/steam could cause serious scalding.
Place the direction lever into the reverse position, and than open the
main steam valve. The engine should start to move off in the reverse
direction. From starting from cold it will be jerky, this is normal, as it has
to clear the condensate from the system. The more the main steam valve
is opened, the faster the engine will go; our advise is to start slowly and
learn the road with your engine.
After a minute or so, remove the cloth and continue running. I running it
is correct practice to balance the boiler pressure against the load being
pulled and the track conditions.

Page 7
With a light load and level track the pressure may need to be only 25-30
p.s.i. therefore, turn the gas control valve down to keep this pressure.
When running a heavy train with steep gradients, increase the pressure
by turning up the gas.
The ideal running pressure can be learned by experience and is one of
the pleasures of running a live steam engine.
There is no need to have the safety valve constantly blowing off (it is
what its name implies - a safety vent for excess steam pressure). In all
our designs, the gas has been programmed to run out just before the
water, thus it is important not to refill with gas alone in order to lengthen
the run by a few minutes. When the gas runs out a complete gas, oil and
water service must be done (remember GOW, also remember to shut the
gas regulator before refilling, and do not refill with gas near any other
live steam loco).
When the locomotive slows as the pressure falls at the end of a run, stop
the engine. Gently open the lubricator valve and blow out any condensed
water. If you intend to continue running, close the drain when you see oil
coming out of it and carry out a general refill. If it is the last run of the
day, leave the lubricator open and blow the lubricator clean.
Continuous Running
To run for longer periods of time than the normal “one fill” system you will
require a Boiler Filling system. This consists a pump bottle with tube
attached and a replacement boiler filler cab, which has a non-return
valve on its underside. For the first fill service in the normal way. Then
run for about 15 minutes, now have a look at the water level. You will
probably need to pump some water into the boiler. Lift and tilt over the
cab roof to uncover the filler cap, place the tube in the hole and holding it
firmly, pump water into the boiler untilo the gauge glass is showing ¾ full.
Keep an eye on the water gauge and try to run between ½ and ¾ of the
glass.
After another 15 minutes running you will need to refill the lubricator and
top up the gas tank. Also check the water level and top up if necessary.
Stop the loco in a convenient location, away from other locomotives and
turn off the gas. Ensure the fire is completely out and then top up the gas
tank.
Blow around the engine so there is no residual gas about, then re-light
the fire. To refill the lubricator first put the loco in neutral (mid gear).

Page 8
Open the under floor drain valve then gently open the steam regulator.
When the lubricator has blown clean, close the regulator and remove the
lubricator cap. Now close the drain valve and refill with superheat steam
oil to the correct level. Re-fit the lubricator cap. All this time the engine
has had the fire alight and will have a good head of steam, so now carry
on running.
Keep an eye on the water level at all times and try to refill the gas tank
and lubricator every 20 minutes to half an hour.
End of Run
As previously mentioned, the locomotive will slow (due to pressure
dropping) when the fire has gone out, stop at a convenient place and
open the lubricator drain valve. Blow out all condensed water and the
remaining oil. Leave the drain valve open and allow the remaining steam
to blow out. The locomotive should be allowed to cool. When cool clean
the engine, check the motion and oil if necessary. The locomotive should
always be put away in a clean condition as it attracts less dust and is
always ready for the next run (or to be shown to an admiring friend).
Always leave the lubricator drain valve and the boiler blow down valve
open so that the boiler will not be strained if subject to any temperature
change. It is advisable to store the locomotive where any residual drips
of oil or water do not matter.
Blocked Gas Jets
If the gas jet becomes blocked with particles of dirt within the gas, the jet
will have to be removed and cleaned. With a spanner or pliers carefully
undo the pipe union on the gas control valve. Remove the pipe hand jet
holder assembly from the burner. Holding the jet gently in vice, unscrew
the jet. To clear, place the jet nozzle against the inverted gas can nozzle
and clear the jet with a blast of gas. Under no circumstances use a
pricker wire, this will damage the jet hole.
Replace the jet in the holder, ideally using a thread sealant sparingly on
the threads. Ensure it is tightened up firmly. Replace the assembly into
the burner and re-connect the pipe to the control valve. Ensure this is
done up tightly, test CAREFULLY for gas leaks, first with a 50/50 mixture
of washing up liquid and water, and then if no bubbles are showing, with
a flame and the gas “just on”. Tighten if required.
