Hi everybody

In one part of my layout I have a terminal station and I want that the trains to reduce their speed as they enter it and finally to stop. Everything in my layout is digital, but I'm not using a computer. What do you recommend? Do you think that to use one or maybe two 32V transformers is appropriate? Otherwise I would have to buy a lot of deacceleration modules... Or is there a better alternative? I saw Viessmann has a resistor module, but they say is not good for digital (which is logical, I think, but sometimes there are tricks...)

Cheers,

Nuno

Hi Nuno

There was an interesting thread on this earlier in the year:

https://www.marklin-user...earchTerms=reduced,speed

I am also looking for a half/reduced speed "black box", my attempts with diodes and Zener diodes were not that great and somehow the mfx locos get a bit confused and break out in a super jerk mode [:0] while in the reduced speed section. So I just use a resistor for now which is also not very statisfactory.[V]

I was the one starting the earlier thread (wow, was it really all the way back in february?). I have since had to move, and therefore haven't got the time to get on with this project. I have started to look a bit at it again, but there is quite some way to go before I have a working prototype.

But after looking at the module at Tams, I'm not sure I will continue my project. The Tams one seem to do more or less exactly what I wanted to achieve. It is somewhat larger than I would have imagined was needed, but I don't think that matters much.

Hello again

Thank you all for your suggestions.

Cheers,

This seems like a very good choice. It doesn't change the voltage of the track, but only modifies the signal sent to the track. It has a more advanced version that replaces the Märklin 72441 signal module. Just one problem with it: If you stop on the border between sections there will be a potentially dangerous shortcut!

Hi all,

I have been following already some time this great forum, and it's time to join the gang.

But to the subject:

The Tams-breaking module is even better as it first looks:

1. There is no danger for shortcuts, as the module detects the shorts and quickly cuts of the own signal if needed.
2. It works with every (Motorola-)decoder. As said before, it modifies the speed step to 4, when braking starts, and at the stopping point (e.g. contact track) the speed is set to zero.
3. All locos/trains stop at the same point (depending how to stop impulse is created, circuit-/contact track)

One negative feature is that one have to reset the module (push button) when a train runs by to opposite direction.

Only one loco can brake at a time because of the one single stopping point.

With the M* 72441 module the braking distance depends of decoder settings and incoming speed, so every loco stops in different points, and locos with unregulated decoders stop usually right at start of the braking section.

Yes,
Tams indeed seems to make interesting items for a person like me. Thank's for the hints!

However, it's a pity that this brake signal doesn't mix in a DCC brake signal as well. AFAIK it's very easy to do in DCC, as there exists a broadcast address. So for the time beeing, I'll stick to my solution, using DC brake signal, and relays to switch it in, for those locos that don't have Lissy senders. It doesn't give the slow down possibility, but works ok anyway.

Hi Juha,

congratulations: beautyful & well documented k-layout - it's nice you didn't forget about the kids
I also like your scratch-built Finnish engines [:p]
