All,

I'm currently in the process of digitising a Spreewald locomotive I recently aquire.

The loco has 3 lights on the front and 3 lights on the reason (examples) below. I have a question on how lights are used on the prototype Spreewald/in the real world. Is the top one the normal running light and the bottom two are the high beam equivalent or am I over thinking this and they're all on together?

The decoder I have let's me do lights/directionally forward and backward. However, I also have an additional 8 outputs so have the flexibility to set this up in a more prototypical way.

I Britain, the lights are lit in pattern to show what type of train is being pulled, ie goods, passenger, express etc. Whether that applies in this case I'm not sure images.jpeg

Curtis,
I think it would depend on the line and country the prototype was running in?

But it is your loc (and line) so you can choose.

As Spreewald is a German Loco, German practice is to have all 3 alight in the direction of travel. You can see that on the loco below going bunker first. 0CD1DC38-6186-4400-A24B-D4DC9DA3A33D.jpeg

JonD: Absolutely right, and well observed!

According to the rules:

Signal Zg1 (Spitzensignal) - the leading loco/wagon of a train has always to show 3 white lamps in form of an "A" (in order to differentiate from cars w/ 2 lamps only).

An exception on the Deutsche Reichsbahn network still today:

Signal Fz1 (Rangiersignal) - just 1 bottom lamp (usually in driving direction bottom right) - applies ONLY for switching / shunting locos - NOT for trains

Although the Zg1 became mandatory in the 1950's, the Berlin S-Bahn still had many old trains running with 2 lamps only - see here in 1986:

As always, I'm impressed with the depth of knowledge and helpfulness!

Paul - I never knew that about British running! Thank you

I didn't have a particular prototype in mind. I was mostly starting the conversation as I wired up the loco. For now, I'll start with 3 forward/ 3 rear in the direction of travel. John also messaged me separately and mentioned that when running backwards without a train they run with a red lamp which I made try my hand at adding in the future

Side note, until last year - I live 2minutes walk from where that last picture was taken (Humboldthain)

Rangiersignal = shunting/switching indication.
