LGB 20670 track cleaning locomotive

All about LGB 20670 track cleaning locomotive

Most of rail modeller owning an outdoor layout dream the LGB 20670 track cleaning locomotive running on their track. Why? Because people using track power on their outdoor layouts have a big problem: cleaning track! Grit on the railheads, oxides of the track metal, plastic from your standard wheels, leaf litter, tree sap, bird droppings…and so on. So you need something efficient and comfortable making this job for you: the LGB 20670 track cleaning locomotive is the best solution.

LGB 20670 (former LGB 2067)
LGB begin to produce a track cleaning locomotive in 1992: the first model was yellow and was discontinued in 2006/2007; from 2005 it received a decoder on board.








LGB 21670
In 2008 came out the new version with an orange livery and a decoder onboard.









LGB 20670 track cleaning locomotive works with two motors. The drive motor propels the loco down the track. The second motor rotates a pair of cleaning wheels opposite of the direction of travel for safe, effective cleaning of your LGB brass rails. The body is modeled after track maintenance equipment found around the world. Directional lanterns and flashing warning lights tell you the status of the loco. On LGB 21670 the onboard MTS decoder makes this loco ready for operation on your analog or digital layout, indoors or out. Not for use with “Ni” nickel-plated track.

The model features:
- weather-resistant construction
- factory-installed onboard decoder for MTS and analog operation (LGB 21760)
- three-way power control switch
- protected gearbox with seven-pole Bühler motor
- four powered wheels
- built-in speed control
- cleaning gearbox with high-torque Bühler motor
- low-abrasion, counter-rotating cleaning wheels
- six power pickups
- voltage stabilization circuit
- automatic directional lanterns
- roof-mounted hazard lights
- length: 435 mm (17.1 in)
- weight: 2900 g (6.4 lb)

Tips&Tricks: how use the LGB 20670 track cleaning loco

If the rails are extremely dirty, hand-clean a small section of track about 300 mm (1 ft) long. The 50040 Track Cleaning Block is perfect for this. Since the 20670 requires current from the rails to operate, you need some clean rails to start the loco and the cleaning process.

Set the slide switch in the engineer's cab for track cleaning.
Lift off the round plastic cap on the roof of the cab, and turn the locomotive speed control to its minimum setting.
Turn your speed control to full power. By providing full power, the cleaning wheels will turn at maximum speed. However, the loco will move very slowly, since the loco speed control is at the minimum setting. As described earlier, this will provide the maximum cleaning wheel speed relative to the rail head, and therefore, it will provide the maximum cleaning effect. If the 20670 stalls on grades or curves, adjust the locomotive speed control, but only in very small increments. Eventually, you will find the optimal speed for your layout.

Normally, this simple procedure will clean the most oxidized tracks so well that your LGB trains will run easily. However, my experience shows that when the track is very dirty it is advisable to clean your tracks twice-once in each direction. This reduces the effect of mountain and valley grades on the cleaning process. If you use a handheld cleaning device, the abrasive speed is slow, and the pressure is inconsistent. The fixed abrasive grinds dirt into the rail, and large amounts of brass may be lost. On the other hand, the 20670 works efficiently at high speed and consistent pressure. Dirt is thrown away from the track, and only a tiny amount of brass is removed.
