LGB 1015U, 1201, and 1203

[LoveOnRails]

So, I inherited a bunch of G-scale track from a now deceased G-scaler, and am in the planning stages for building my own G-scale garden railroad from this. Amongst the track components is a piece having 3 components fastened together, a 1015U, a 1201 and a 1203. See attached pic. I googled what each of the pieces do, but as a trio I’m baffled as to what collective function they have. I also saw this trio of components sold as a unit at a recent G-scale train show. What especially puzzles me is why a switch machine (1201) is attached without a turnout. As configured, I would say that when a train passes over the 1015U, it throws the switch on the parallel track, but I fail to see why that would be useful.

So, I’m looking for enlightenment over this contraption. I would appreciate your insights.

Welcome to the forum.

I too can't think why a point motor would be attached to a 1015U. It's an isolation track and the motor and auxiliary switches don't seem to be required.

Unless someone else would know....

The only thing I can think of is the point motor, with the attached auxiliary switch, is use as a remote way of switching on & off a dead section of line passed the isolation rail.

I agree with the others it’s a type of remote switch,

It would probably work well with the Lgb DC electrical system - can’t remember the name,

By doing it this way does it minimise voltage drop to/ from a control panel?

It could be used with another isolator to act as reversing unit on a loop.

I would believe the 1201 motor is being used with a control box to trigger the relay in the 1203, which provides power (or not) to the 1205U. It would be paired with another 1205 for the isolated section. Basically its just a way to control power in an isolated section of track. The EPL system was/is pretty sophisticated.

 

[Software Tools]

Most likely it is was being used as part of some EPL based automation to switch power on/off to a section of track as required for whatever the automated function required.

You can just see a red wire from the 1203 heading under a sleeper on the 1205u isolation track section. The 1201+1203 combination in this case is simply being used as a relay, which is conveniently located at the track section concerned.

welcome,

some uses for that combination:






just, what came first to mind.
maybe it would be helpful, to read the LGB manual: http://kormsen.info/lgb-manual.pdf

Welcome to the forum! As you have found out, there's a lot of useful information on here, just beware of the humour.
It wouldn't be a way of changing a signal by any chance?

I did wonder about that, but it is a point motor rather than a signal motor....

True.

Wow!! So many helpful hints! The diagrams were the most useful to me. Thanks to all who contributed, though. — Mark
