ROYAL HUDSONS #2850 & #2860
LIVE STEAM - ALCOHOL FIRED

C.P. Royal Hudson Live Steam - Alcohol Fired
Designed by Henry Bowen and introduced in 1937, the semi-streamlined
Hudson was selected to haul the 1939 Royal Train that carried King George
VI and Queen Elizabeth on their journey across Canada. No 2850 was chosen
and was turned out in a spectacular Royal Blue and stainless steel livery to
match the 12-coach blue and silver train.
So impressive was 2850’s performance on the 3224 mile trip that Canadian
Pacific applied to Buckingham Palace for permission to officially designate
the class as Royal Hudson, a request that was granted. Subsequently all 45
members of the class carried a cast Royal crown on their front running board
skirts. The Royal blue livery on 2850 only lasted for the seven months of
the summer of 1939 and after exhibition at the New York World’s Fair it was
replaced by the standard passenger livery of maroon panels with grey boiler
cladding and cylinder covers, which it has to be said is still a spectacular
livery!
Although designed as express passenger engines and capable of over 90mph,
the Royal Hudsons were also used extensively on freight duties, but it was on
the prestigious, passenger trains such as the daily Dominion that they made
a name for themselves with 1250 mile runs between Calgary and Ft. William
(Thunder Bay). On the cross-country runs it was common to have several
express reefers at the head end between the engine and baggage car.
TheRoyalHudsonsran inservice rightup tothe withdrawof steamby Canadian
Pacific in the summer of 1960 when most of the class were scrapped. Happily
four have survived to this day in preservation, including 2860 currently in steam
in British Columbia.
Also a 2850 is preserved in its Tuscan and grey livery and has place of pride
at the Canadian Railway Museum at Delson just outside Montreal.

General information about The
Royal Hudson Model:
Operating a model live steam loco-
motive is much different from running
an electrically powered engine. It is
a more hands-on, interactive experi-
ence.
The locomotive must be periodically
fueled, oiled and watered.As supplied,
the locomotive is manually controlled,
which means that you must actually
drive the locomotive using the controls
in the cab, just as you would a full-size
engine.
The performance of the engine is also
unlike electric locomotives. The loco-
motive should pull a dozen or more
standard-size freight cars on good,
level track. Grades and sharp curves
will diminish its capability.Agood engi-
neer will learn the engine’s character-
istics and idiosyncrasies over time, to
get the best performance and longest
duration from it.
Safety:
For your safety, there are certain rules
that should be observed, as follows:
1. The safety valves have been set
at the factory to release at around 60
pounds per square inch of pressure.
Never tamper with the safety valve.
2. The alcohol firing system has been
designed to use denatured alcohol.
Do not use an other fuel. Other fuel
will create a dangerous condition, and
will also damage the locomotive!
3. Always make sure the fire is out
before refueling the locomotive. The
Alcohol fire is nearly invisible so be
absolutely sure that there is no flame
burning around the engine when refu-
eling is being done!
4. A steam engine gets hot, Be care-
ful.
The locomotive and tender should al-
ways be carried separately because
of their weight. We suggest carrying
the locomotive to the track by support-
ing it underneath the wheels with both
hands, as opposed to lifting by the pi-
lot (which may not stand the stress)
and rear beam.
For general carrying, the engine can
be carried on a carrying tray with han-
dles.

Please read following directions be-
fore unpacking your locomotive.
1. Remove foam around the locomo-
tive. Slide the inner box cover to the
side, and open the inside cardboard
box with a cutting knife.
2. Lift the locomotive from the card-
board box.
3. Place taped locomotive on a flat
surface. Carefully cut the tape along
the wood board side surface. Be sure
to cut both sides of the wood board.
Slowly lift the tape from the locomo-
tive. Be very careful with small parts.
Tape cannot be re-used to re-pack the
model. Use new packing tape if nec-
essary.
Notes on Radio controls:
Althoughthislocomotivewasdesigned
as a manually controlled locomotive,
there is no reason why radio control
(R/C) cannot be fitted, with some inge-
nuity. A two-channel radio is all that’s
necessary, one for the throttle and one
for the reversing lever.
The reversing lever will have to be
modified so that it does not lock in
position, but it must still have stops at
either end of its throw for proper posi-
tioning of the reversing gear.

that you’ll have to stay with the engine
through the run if you want to change
its speed or direction.
If you have a suitable track, the
engine can be left to run on its own
at a steady speed. Keep your eye on
the water glass. With practice and
good weather, steady runs of an hour
or more are not uncommon for this
engine.
Axle Pump:
This locomotive is equipped with an
axle pump and bypass valve. The
pump moves water from the tender
to a check valve on the locomotive.
The bypass valve is located on the
right side of the locomotive under the
cab. When the bypass valve is com-
pletely shut, water is pumped into the
locomotive. When the bypass valve is
open, the pump will re-circulate water
back into the tender. With careful
adjustment of this valve, the engine
will always have enough water to
keep running for long periods of time
until the tender water tank needs to be
refilled. The tender is also equipped
with the hand pump, which needs to
be used to prime the axle pump. Only
two or three strokes are necessary to
prime the pump.
Shutting down:
To shut the engine down, simply close
the Fuel valve and use your CO2 tire
inflator to extinguish the fire.
Make sure the fire is completely out
before turning off the steam blower if
engine is standing still. This will mini-
mize the chance of the paint getting
scorched from any fire still burning in
the firebox that is not vented!
After the fire is out at the end of the
run, open the blow down valve and
leave it open. This will relieve the
boiler of what little pressure remains
Because of the size of this engine,
blowing down could take several min-
utes.
After a day’s operation in the garden,
you’ll probably find that your engine
has a coating of oil all over it. This
is steam-cylinder oil that has been
exhausted from the stack. A simple
wipe down with a dry cloth is all that’s
necessary to restore the engine to
pristine condition.
This is best done while the engine is
still warm. Wipe any grit and excess
oil from the wheels and running.

Preparing for operation:
1. Oil all external moving parts
of the engine and tender with a high
grade,lightweight machineoillike 3-in-
1. Don’t forget the wheel bearings in
the pilot and trailing trucks, as well as
those in the tender. Don’t over-oil; a
tiny drop will do the job.
2. Place the engine and tender
on the track and couple them together.
The drawbar between the units has
two holes. For tighter curves, use the
rear hole. For wide-radius curves, the
engine and tender can be coupled
more closely together, using the front
hole. Then connect the water feed,
fuel and water return lines.
3. The displacement lubricator is
disguised as an air tank under the left
hand running board. This lubricator
ensures the cylinders and valves
are properly lubricated inside. As
the steam passes through it, a small
amount will condense into water. This
water will sink to the bottom of the
lubricator, forcing a similar quantity of
oil into the steam line and thus to the
cylinders.
Remove the lubricator cap and draw
out any water from the previous run
with a syringe. Use only proper steam
cylinder oil. Fill the lubricator, but leave
a small air space between the oil and
the cap.
4. Fill the tender with water.
Open the blower valve a little and
pump water into the boiler. Fill the
boiler until the water reaches the top
of the glass.
This is a BIG locomotive and it will
take a lot of water. Do not overfill the
boiler; there needs to be room above
the water for steam to form.

C.P. Royal Hudson Live Steam - Alcohol Fired
Use only distilled water in your
engine’s boiler. Tap water contains
minerals that will leach out, cloud the
water glass, and ultimately affect the
performance of the engine.
Your locomotive burns denatured
alcohol. The fuel tank is located in
the tender beneath the oil bunker.
Alcohol can be purchased at most
home improvement stores.
The alcohol should be either Methyl
alcohol or preferably Ethyl alcohol
which will burn at a higher tempera-
ture, making the locomotive more effi-
cient.
Use a syringe or a small funnel to fill
the fuel tank with alcohol. The tank
is designed to meter the fuel into the
burner. It should saturate the wick
material without leaking out over the
top of the burner causing a pud-
dle of alcohol under the locomotive.
Completely clear up any split alcohol
before attempting to light burner.
When fueling the locomotive the fuel
valve should be shut. Replace filler
cap immediately after filling tank. The
alcohol will cause the O-ring to dry
out, use a small drop of machine oil on
the O-ring to keep it pliable.
Firing Up:
Close the throttle and blower valve.
Place the battery powered suction fan
in the smoke stack, but do not turn
it on yet. Open the fuel valve on the
tender 1/2 turn. Wait until the burner
wicks are saturated with fuel. Open
the fire door with the pull wire and light
with a fire stick. Make sure the burner
is lit by looking in the fire door, then
immediately turn on the suction fan.
It will take approximately 7 minutes
to raise pressure. Once the gauge
reaches 20 lbs, you can shut off and
remove suction fan from the stack
and then turn on the engines internal
blower. At this point steam will rise
rapidly!

Condensation that has formed in the
blower line will run out the bottom
of the locomotive, and then the dry
steam will blast up the stack creating
a draft pulling the hot gases forward
through the flues. When the gauge
reads 50 lbs. the engine is ready to
run.
Drain Cocks:
This locomotive is fitted with working
drain cocks on the cylinders. When
first starting out, the cocks should
be open (levers moved to “outside”
positions). This will allow water in the
cylinders to drain while the cylinders
heat up to working temperature.
As steam enters cold cylinders, it
condenses, so expect a fair amount
of water to come out at the beginning
of each run. Once the cylinders have
warmed up, you can close the drain
cocks. To close them, move the levers
to the “up” position.
Running:
Move the reversing lever at the right
side of the cab to the forward posi-
tion. With the engine on the track,
and without a train, open the throttle.
The engine may need to be pushed a
little to overcome the steam condens-
ing into water in the cold cylinders,
but the open drain cocks will minimize
this. After a few moments, the engine
should take off on its own, moving
away smoothly.
Once the engine is running smoothly,
a train can be coupled on and the run
can proceed.
Since all of the locomotive’s functions
are controlled from the cab, it can be
driven like a full-size engine, meaning
