I am trying to set up a basic Signal with 3 states Red, Green, and Dark. I have tried all of the various Signal Heads. The signal is being driven by an ESU 51820 Accessory Decoder using 2 of the 4 outputs. 1 for the Red Bulb on/off, and one for the Green Bulb. Call them XT1 and XT2, I am using THROWN to turn the lamp on and CLOSED to turn it off. This was the only way I could see to be able to have a DARK state.

The German signals don't work that way. Depending upon which signal type
they are more complex in that they show aspects and can show more than one
aspect at the same time depending upon whether there is a distant signal
attached to the same mast or whether there is a switching signal attached
to the same mast.

I am speaking from knowledge of German signalling but a novice at JMRI. It
was my understanding that JMRI had the German signals in its configuration
but what I do not know yet is if those signals are set up using the logix
and how that logix output is designed to get to the signal? I'm thinking
maybe the JMRI 'way' is the expectation of using a manufacturer's signal
decoder units such as those sold by Marklin or some other European
manufacturer.

I will be following this thread closely as I will going down the same path
here shortly although my plan was to tie my signals to CMRI outputs that
then feed a decoder board I originally designed and built to be able to
drive my Brawa signals. Unfortunately Brawa stopped making them and they
are the only fine-scale signals I have seen. Until someone else steps into
the breech I will be stuck with the more clunky Veissmann signals.

FYI, with JMRI 4.8 or later the ESU SwitchPilot decoders have JMRI decoder definitions, are fully programmable on Program Track (read the ESU manual to see how to connect for Program Track Mode) and Program on Main (when fitted to layout).

Furthermore, the Single CV Programmer tool in JMRI can also be used. For Program on Main of these particular decoders with this tool, you need to select "Ops Accessory Byte", "Decoder Address" and use the decoder address (in the range 1-511) rather than the output address (in the range 1-2044).

Note that with SwitchPilot decoders, the usable range is limited to decoder addresses 1-510 and output addresses 1-2040 (commands to outputs 2041-2044 are ignored).

Probably easiest to create a head using the Double Output driver. This will display correctly when you select Dark, Red or Green.


Create a mast using this head as a head controlled mast and as long as it does not have any yellow colours it should display fine.


Alternatively you can just create the mast and use the matrix driver with two turnouts, and configure that.

We have a (partial) implementation of one set of German signals, see:



There’s a comment on it that says "Missing aspect mapping, not finished.” so it probably needs a bit more work. I’d be happy to help somebody with the needed knowledge set that up.

What’s there is enough to display the signals, but not quite enough for JMRI’s automated signal logic to e.g. figure out which aspect has to appear before which other aspect. FOr more on that see

Depends which signal system you try to implement.? The H/V-system available in JMRI is pretty simple, it knows only three main signal aspects Hp0/Hp1/Hp2.? The advanced signals are effectively put in parallel with the main signals.There is no connection with the next block unless an advanced signal for the next main signal is at the same mast as the main signal, thus there really is no destination mast needed.

Hp0 means stop, Hp1 means go.? Hp2 means go like Hp1, except with reduced speed.? However, Hp2 is not signaled because track occupancy in the block ahead, but because of speed limitations due to the radii of turnouts and curves that the train has to follow.? Switching signals Sh0/Sh1 make things slightly more complicated.? However, all signals in the H/V system are best treated as turnouts and Logix.?

Signal logic or signal mast logic in the JMRI system is more suitable for the newer Ks-signals.
