LGB 20670 Track cleaning loco
Backfitting of a LGB “Track cleaning loco” with 3-pin-gear and an old DEG-electronic with a XL-
decoder.
The base CB will be removed completely, light roof and front building light will be modified.
ict.-1: LGB 20670
Needed Parts:
•1x 8150001 XL-Decoder
•Relais 24V / 5A (e.g. RTE24024 Schrack) with free-wheeling diode
•Miscellaneous cables
Backfitting:
Remove rear (short) bonnet (Release 2 screws in the frontside).
Remove crossing bonnet in front of the driver’s cab (Remove 2 screws below the stairs).
Remove driver’s cab (2 screws in access ladder and 2 hidden in the fuel tank).
Remove front (long) bonnet (1 screw before the cleaning block and 2 in the bracket of the cleaning
block).
On the porch CB swap the red with the black cable (Motor turns against driving direction).
(Who want’s a meeker cleaning don’t touch the cable and the cleaning motor turns with driving
direction)

ict.-2: New soldered cleaning motor cable
Assemble completely cleaning porch.
Remove propulsion unit from the chassis (Remove 4 screws from the brackets.)
Rebuild the propulsion unit for the 4. (yellow) cable
Basics:_Digital_compatible_gears/en
Cut the 4 light roof cables, light rear, jack and the 3 cables to the slider porch from the base CB.
Remove base CB complete.
lug the rest of the 3 gear cables of XL-decoder on the propulsion unit and assemble the gear.
Assemble the XL-decoder and relais on the lead weight.
Connect cable like ict. 3:
Connection plan
Gear cable on M+(green) , G+(brown) , G-(white) , M-(yellow).
Cable of slider porch “+”(white) , LV(brown) , Relais contact(green).
Light rear on “+” and “LH”.
Relais coil on “+” and “F3” (Follow the polarity of diode).
Second relais contact on “-” .
While the old jack is not protected against reversal polarity, the cable will be removed completely.

ict.-3: Assembling and wiring of XL-decoder.
Before the first test you must program the decoder:
CV50 = 5 (light to 5V)
CV53 = 5 oder 197 (F1+F2 5V for blinking light on roof)
CV55 = 2 (F1 blinking with 0,5sec. clock)
CV57 = 16 (F2 coupled on F1)
CV56 = 1 (F2 switchable with key 1)
CV113 = 129 (F3 with key 1 for cleaning function on driving forward)
Check basic function:
Loco will drive forward and backward.
Light front + rear glows depending on direction, when turned on.
With Key 1 you can turn on the cleaning motor (only forward).
ict.-4 : Changes on the light CB on the roof.

Remove roof from driver’s cab
Desolder the diode from roof light CB
Solder additional cable (in ict.-4 white) on diode soldering point.
Extend the remaining 4 cables, for a better assembling.
Assemble driver’s cab on the chassis.
Assemble the remaining cables like the drawing:
Connection plan
Black cable from “red/black” on “+”
Red cable from “red/black” on “LI”
New white cable on “LV”
On any black cable of the last cable on “F1” + “F2”.
Now you can check the remaining functions:
Interior light glow in both directions, when turned on.
Yellow lamps on roof blinking alternately, when key 1 on.
After successful check assemble the remaining parts.
Additional possibilities:
To clean the track on highly polluted tracks we recommend assembling of a voltage buffer
(8151001) or a goldcap buffer (8151501).
If you wish you can trigger the functions individual:
(CV54 + CV56 = 2) to switch the roof blinking light with key 2
Red cable from roof light on “F4” in place of “LI” (change bulb to 19V)
