20670
Track Cleaning Loco
THE MODEL
This unique locomotive is the pro-
duct of years of research by Ernst
Paul Lehmann Patentwerk to
solve the complex problems of
track cleaning, especially on out-
door layouts.
The 20670 has two motors. The
drive motor, located below the
cab, propels the loco on the track.
The cleaning motor, located in
front of the cab, rotates a pair of
cleaning wheels. These low-abra-
sion wheels rotate opposite of the
direction of travel for more effec-
tive
cleaning.
wheels also feature special flan-
ges to protect the plastic guides
found on LGB switches and cros-
sings.
With this patented design, the
20670 can safely and efficiently
clean the rails of your LGB track.
The body of the 20670 is modeled
after prototype track maintenance
equipment.
This model features:
- weather-resistant construction
- detailed cab interior with
engineer and controls
- three-way power control switch
- protected drive gearbox with
seven-pole Bühler motor
- four powered drive wheels
- on-board speed control
- cleaning gearbox with high-tor-
que Bühler motor
- low-abrasion, counter-rotating
cleaning wheels
- six power pickups
- voltage stabilization circuit
- lighted cab interior
- automatic directional lanterns
- roof-mounted hazard lights
- length: 435 mm (17.1 in)
- weight: 2900 g (6.4 lb)
OPERATION
Operating Modes
The 20670 is equipped with a
three-way power control switch
(Fig. 1a, 1b). The switch is located
inside the cab, and it can be ope-
rated through the open window of
the cab.
Position 0 : All power off.
Position 1 : Drive motor on. Clea-
The
cleaning
ning motor off. This
position is for opera-
ting the 20670 like a
normal LGB locomoti-
ve.
Position 2 : Drive motor on. Clea-
ning motor ready. This
position is for track
cleaning.
The 20670 is also equipped with
an on-board loco speed control
(Fig. 2), which is concealed under
a black cap on the roof of the cab.
This control regulates the speed
of the drive motor.
Hint: The on-board loco speed
control does not work (and it not
needed) with the Multi-Train
System. When operating with the
Multi-Train System, the loco
speed is regulated with the MTS
Control,
while
wheels rotate at maximum speed
(see Track Cleaning).
Track Cleaning
Layouts with analog control (tradi-
tional power pack and throttle):
- Set your layout speed control to
zero.
- Put the 20670 on the track.
- Set the 20670 on-board speed
control to a middle position,
roughly between the fastest and
slowest position.
- Set your layout speed control to
the highest forward position.
The 20670 will move forward, and
the cleaning wheels will clean the
rails.
Hints:
- The speed of the track cleaning
loco is adjusted with the on-
board speed control. The layout
speed control always should be
set to the highest speed, so the
cleaning wheels are turning at
maximum speed.
- The cleaning motor operates
only when the 20670 is moving
forward. This makes it easy to
clean dead-end sections, like
sidings.
Layouts with digital Multi-Train
System control:
- Place the decoder-equipped
20670 on the track.
- Select the loco address and run
the loco forward at moderate
speed.
Press the function button on your
Train Mouse or the F1 button on
your MTS Remote. The cleaning
wheels turn and clean the rails. To
stop the cleaning wheels, press
the function button or F1 button
once more.
