Conversion
of
American
Flyer/LTI
Geep
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
|
Modification
for
DC
Motor
operation
|
The Lionel LCRU
(LiontechControlReceiverUnit) was designed to use AC
motors, but by adding a rectifier as shown in the
drawing, you can use it to power DC can
motors and have full functionality. |
Explanation
of
the
Modification
for
Two
Rail
operation
|
Note
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
Headlights
are
wired
for
directional
control.

Here
is
the
Lionel
LCRU
Installed
in
a
AF-LTI
GP-7.
It
all
fits
nicely
with
the
only
modification
to
the
LCRU
being
the
Heat-sink |
| The
Antenna
is
mounted
in
the
roof
of
the
Shell
with
Double
sided
Tape |
 |
 |
The
Original
Heat-sink
is
replaced
with
one
made
from
a
piece
of
5/16x1/16
aluminum
formed
as
shown.
It
is
mounted
to
the
frame
with
two
4-40
screws.
The
program
switch
is
mounted
as
shown
in

lower

of

| This
shows
the

choke
mounted
