Hi TT, welcome to the forums. You need a sugar cube speaker. There are more threads here on them than you can jump over. Do a forum search on sugar cube.

Hi Vic, welcome to the forums.  I would suspect, if you have connected to 2 separate loops, one connection will be at reverse polarity to the other And you get the short as soon as you switch the points. 

 

May I suggested you look at the sticky thread at the top of this forum too - Getting started with track extension packs.  It will have lots of useful tips on layouts, including this problem.

The resistor’s job isn’t to protect the decoder, it’s to protect the LED.  Without the resistor, the decoder has sufficient current capability, 100mA, and voltage to destroy the LED without decoder overload.

 

There‘s also nothing wrong with a resistor in the blue wire, it just adds to the total resistance in series with the LED which will make it dimmer.

To program the decoders, you do this by pressing the button on them for programming mode, throw the point/slip element on your schematic that you wish to control, then go back to run mode and it’s done.  It’s all explained in the decoder documentation.

Dennis’s post led me to read back a bit and I find I seem to have missed Phil’s reply to me on 14 v 128 speed steps, hidden as it was in a useless yellow box.  My mistake Phil, I was sure I’d seen this in a TTS leaflet but not so.  Interesting though re-reading the CV29 notes which indicate it is usually not necessary to edit bit 1 as the decoder will handle it automatically.  Does that mean you can set your controller to 14 and lights will still work as the decoder is still on 128?

Decoder should be fine, no idea about motor problems.

Or to put it more conventionally, no functions, just motor control.  There are no features on an 08 that can be enabled with functions.

To me because of the hill and the angle, the engineers were in 2 minds as to building the bridge across or along the tracks (with apologies to the Goons, Bridge on the River Why).

Now I get the difference as well Ray.  All I was looking to replicate was possible track routes, what I forgot was being able to replicate the actual throwing the tie bars with the added complication of frog switching.  I’d go further than RDS too, an elegant solution Hornby could publish in the manual, not a workaround.  After seeking your permission of course.

Given entering the correct loco with the correct R number gives you all of the correct sound functions, the decoder must be correct and Option 2 is most unlikely to get you anywhere.
