Cold-weather running
The weather can dramatically affect
the performance of your
locomotive. Cold and wind can
decrease efficiency to a
disappointing level. Butane gas
becomes liquid at 32̊F and will not
work. As it approaches 32̊F, its
pressure (and effectiveness)
diminishes.
The coal compartment in the tender
in which the gas tank resides can
be filled with warm water in cooler
weather. This will warm the gas in
the tank and keep its pressure up;
which will cause the engine to
operate in a much livelier manner,
much as it does in warm weather. If
the water in the tank cools, just
replace it with warmer water. Empty
the tender at the end of the day's
run.
Never put hot boiling water
in the compartment. This could
cause dangerous pressure levels
in the gas tank. The water should
be comfortable enough to put
your finger in.
NOTE: the temperature of the fuel
supply must always be higher than
that of the engine's gas tank. If you
have warmed the engine's tank and
the supply tank is cooler; gas will
not transfer.
