Conversion
of
American
Flyer
Steam
Loco
to
Lionel
TrainMaster
LCRU
| Using
the
Lionel
Trainmaster
allows
a
collector
operator
to
enjoy
the
advantages
of
new
technology
and
still
keep
compatibility
with
the
older
legacy
systems.
A
TMCC
converted
engine
can
still
run
on
a
conventional
non
TMCC
layout
as
it
would
before
the
conversion.
This
is
not
possible
with
a
DCC
system
Below are links to two drawings. One shows using TMCC with a stock AC motor and the other with a DC can motor conversion |
Modification for DC Motor operation
| The Lionel LCRU (LiontechControlReceiverUnit) was designed to use AC motors, but by adding a rectifier as shown in the DC version drawing, you can use it to power DC can motors and have full functionality. |
Explanation of the Modification for Two Rail operation
|
Note that in both drawings there is a 100 micro Henry choke in the return power lead. This choke is necessary when using two rail track to ensure that the signal is not degraded when the engine is turned around on the track .(Lionel track uses the signal on both outside rails) With a two rail system when you turn an engine on the track it effectively shorts out the RF signal to the LCRU in the engine. This is why you put the RF choke in the common lead. The RF choke looks like an open circuit to the RF and it is not shorted out. Leaving it out, the engine will run fine one direction but lousy if turned around. The diagrams are for a typical American flyer tender. The Headlight and Smoke unit are wired for independent control. The smoke unit is on at a full 14 volts whenever engine is in motion making for a great smoke output. Smoke is off when engine is stopped and the headlight stays on.. When using the AC version you will need to add a additional two contact connector for the smoke and headlight wiring |

Since this is a metal tender I have mounted the antenna under the chassis. The Antenna is made from Fiber Glass vector board with a 24 gauge wire loop woven around into it. The board is fastened to the tender chassis using a screw as a standoff. I will Paint it black to help Hide it. This configuration has proved to be very reliable. |
