Special design features
the start our goal has been to build a coal-fired locomotive with the ease
of a gas-fired locomotive while running but with the fun of building a real coal
fire. Controlling the locomotive had to be possible without you running
after the locomotive or bending your knees more often than with
a gas-fired locomotive.
And we have learnt from earlier coal-fired
locomotives we’ve built that a damper is needed to balance and control
the heat of the fire. The damper prevents the fire dying out or the
safety valve blowing off all the time.
you'll need is a
coal-fired locomotive with running times comparable to gas-fired
locomotives without attending coal or
water. Like your gas-fired locomotive it should be very reliable
and of simple design. It would be very nice to have a neat cab lay-out
with space for loco driver and fire man. And optional full
R/C including damper and whistle.
To make all above
possible we designed a special boiler containing all the
need for a run. So there is no need for a pumping system that in this
scale needs very much energy and shortens running times considerably.
And without pump the loco runs trouble free like a gas-fired loco.
After the run coal and water are topped up. At that
moment you will be really busy with getting the newly added coal
burning and topping up the boiler with water for the next run.
to the very deep and wide firebox in combination with a very effective
steam blower it's not difficult to keep the fire
going. The boiler has a large dual flue design.
This is one of the reasons the steam blower is so effective. The flues
themselves are insensitive to pollution and the design allows the
water level to run very low before they are falling fully dry.
To save you the hassle with steam oil
while under steam, the lubricator is extra large. On top of that the loco has a very nicely designed water gauge.
resulting locomotive is very reliable and of simple design. Long runs as with a gas-fired
locomotive are possible. This makes
the locomotive very suitable for ground tracks also. It has
a very neat cab lay-out. With the
damper you can keep the pressure at a constant
value with any train load and speed. And if you want,
you can not only have a radio controlled regulator,
reverser and whistle but a radio controlled damper as well !
The manual damper lever for manual locos (details here) and in particular the new pressure feedback receiver with automated damper for R/C locos (details here) do make our locos even more comfortable to run compared to gasfired locos.
