Hi chaps,

On my old layout the fiddle yard was automatic with the Heathcote eletrics auto changing the next train for each loop every time one passed. If a loco is running under DCC I gather it would keep running and foul the points? Or am I talking twaddle?

How can you stop a DCC loco or several for that matter to set up this kind of arrangement? Without a computer that is!

I'm afraid you wil need a computer to do this.

Neil - you can do it quite easy without a computer - autochange fiddle yards (one in, next out & so on) with slowdown fairly easy (requires braking modules) - without slowdown even easier.

Working on auto fiddle yards on St.Laurent at the moment - should be completly up & running for the Croydon Exhibition 6/7th October.

Braking modules - as Brian says - and asymmetric DCC would probably do it.

Asymmetrical DCC
BM1 - Simple 5 diode asymmetrical generator
BM2 - Controlled by an external signal both stop and restricted speed control can be achieved
BM3 - Full block occupancy detection and Asymmetrical DCC built into a single unit

Assuming he's using Lenz decoders, or others that support asymmetric DCC!

You can do it by simply cutting the power to the track section as you would with DC.

You can also probably do it with bit switches http://www.dcc-bitswitch.com/ which will work with any brand of decoder.

ASymetric DCC only is supporteb by gold and silver lenz decoders. Im not sure 100% but i think that the last series of zimo, support it.

According to the Zimo manual they do indeed support asymmetric DCC, in their most recent decoders at least.

If you have loconet, you can check Lissy system from Uhlenbrock: http://www.uhlenbrock.de/AVID/ARCHIVE/GR...d/Bes68000e.pdf

Thanks for that, I wasn't aware of all that, I am fortunate in that almost off of my installed decoders are Lenz Gold and so I can use this.

In the next link, you can see a five diodes brake module schema like the BM1 by Lenz.

I hope that it be useful.
