Rehashing an old LGB Zillertal loco RC conversion.

Hi Max,

good luck trying to get the ESU to fit the motherboard - the ESU LS4L you appear to be using may have the correct pins to fit the Bachmann motherboard but unless I was doing something dumb (always a possibility) the 5XL (pin header version) pins did not suit the socket in the Bachmann motherboard.

I swapped this unit for a 5XL with terminals but despite modifying the internal space between the tanks I could not get it to sit down satisfactorily (the steam dome/sand dome section would not sit down properly) hence moving the decoder and the RC receiver to the bunker.

This is how it all fits before closing up the back wall of the cab:



Notice how the four-pole double throw switch, RCA connector and charging socket are all offset in the aluminium plate fitted below the bunker mounts - the decoder is slotted into a notch on the fireman's side of the bunker and screwed to a styrene packer on the right in this upside down view. The CVP Airwire receiver is attached via velcro to the inside of the back cab wall - the 4 way plug is the feed from the battery and the return from track out of the decoder. The ten pin (white) connector is the decoder outputs for lights, speaker output, etc.

The unit is almost finished - just has to have some weathering over the decals that arrived Monday:



If you are interested in the schematics of how I wired it I can scan them and post tomorrow,

Cheers,

NB: Interested in your "Keep Off" signs on the tanks - given that's where I would be standing when filling the sand dome............

(I fire and drive 3'6"gauge steam at Victoria's Bellarine Railway - no Mallets with ex-South African 24 Class #3620 our largest engine currently in regular service)

So, after a wee bit of a hiatus, like 18 months (!) I'm ready to start getting everything fitted up on the LGB Zillertalbahn #2. After consultations with Phil at RC Trains I am now confident I can manage to solder the wires in all the right places so the electrons flow in all the right directions and right places, with minimal risk of white smoke emissions. Just need to hope every thing still functions as it did before I pulled it apart and added a few bit, like sound. So today's little bit of work, the all important schematic. Well, I think I understand me own werk. Tomorrow we getdown to it. Honest. Max.

Behold the workings of my, seemingly unfathomable, logic. An exepert has cast their eyes upon it and found it to be good. The whistle (that ?) trigger goes to pad C on 65c board. The unlabled coily bits at either end are the LGB incandecent lamps being reused.


And all that that involves this pile of bits. Note, batteries now neatly heat shrink wrapped. Oh no, I've now got a heat gun to play with !
