I'm going to be converting the signal masts on my Marklin turntable #7286 to use LED lights, but I'd like to get I'd like to get information regarding the light aspects and color lights used. I'm assuming that the aspects are proceed slowly and stop, but what colors are used and what arrangements of lights.

From the appearance of the molded light with the turntable. it looks like there would be three lights on the top (with a 1 - 2 light combination) and a single light on the lower left.

If we follow the Marklin yard light light example, it would be two red lights, and two white. In the following config:

r wr
w

However, I think it might use a color combination of Red, Green and Yellow. Does anybody have any information on the prototypes?

In the end, I might just do a:

r g or r gr
y y

if I have the space.

Thanks for interesting information anfd the nice photo.

How do you control and power the signal light?

Hi Bart and Intruder,

some answers to your questions : I had a lot of trouble with the Marklin decoder and motor itself, so after my major kitbashing of the turntable I got quite frustrated to see I could not operate the table digitally in a smooth manner.
(https://www.marklin-users.net/forum/default.aspx?g=posts&t=4504)

I therefore went for the search for other decoders. BMB Technik has one that can be built INTO the bridge. So: you only need to supply the brigde, and with the decoder on board you can control the motor, the signal and the cabin light. The nice thing about the BMB decoder is that it operates the signals automatically. When starting the turn, they turn red, when the bridge arrives at the target rail connection, it decellerates (!), stops, and a fraction of a second later the lights turn white.. [:p][:p] Very nice !!

Info on : (unfortunately German, but the pictures speak for themseleves)

Luis (laaves) from Portugal has used a locpilot decoder into his bridge. See (https://www.marklin-users.net/forum/default.aspx?g=posts&t=5998)

As to the signals, as far as I have seen them, they always point outwards. On the digital-bahn site there is a pic (and they also describe it) where both incoming and outgoing signals are on the bridge. I cannot remember have seen this in steamrailroad times, but it must exist. In the original bridges one used a formsignal, that was visible from any position. it was mounted directly adjacent to the cabin.
Now to answer the question, how does the drive know when to leave the bridge ? It is signalled by a horn (see https://www.marklin-user...lt.aspx?g=posts&t=6090).

Incoming tracks were protected sometimes by the orange W-type signals: 'Wartezeichen' of waiting signals. They indicated the locdriver to wait for a hand signal of a signal supervisor to proceed.

Hope this clarifies a few of the operations ...

Thanks Bob, Lars
I have recently ordered the BMB decoder, and I saw the recommendation on their site to mount 4 signals on the bridge, for entering and leaving in either direction.
However, I have never seen that on prototype turntable pictures - that was one of the reasons to raise the question here.

Yes, the W signal at position c I found in older pics. Would those be replaced by shunting signals in the light signal era?

Still wondering if anyone knows how situation b is handled in real life.

Yes, I agree along the lines of Frederik ! Most of the time the locs were driving on sight. I never saw a signal on the exit track of the tt, unless this track was leading outside the BW area. You would always have something between 5 to 20 loclenghts (what a nice unity for lenght [}:)]) to encounter the shunting signal, or even a main signal, or sometimes even a W signal, that was controled by the main signalhouse. Drivers would give a short 'pfiff' to attrack the attention of the signal responsible to get clearance to go out.

Bob

What a fantastic insight. Thanks all of you.
Couple fo question:
Do you have to convert your TT to digital to do this conversion?
BMB decoder - can these be retrofitted at their factory?
I am useless when dealing with small electrical "thinggies"

the viessmann 4017 is a good solution i think, but most tt's 'in nature' had the old shunting signal alike the maerklin 7042 (but more likely the never in model realized 'gleissperre') which can be seen from both sides. i for myself have never seen the 'modern' viessmann 4017 in 'nature' but of course this can have been the reality from about 1951 on. when i build my layout this will be one of my 'medium' problems, to put the signal of my tt's into 'life'.
have fun with yout mrr's around the world whereever you are, which system you like and/or operate

nice pic

now assuming there is a shunting signal at both ends, would they both show Sh1 at the same time?
or would only one end be Sh1 and the other Sh0 ?

Hello every body.
IMHO when the shuting signal were aplied to a TT, the reason for that must be a very buissy betribs werk, where more loks where serviced at the same time - there for the signal would probably not be abel to show akcess Sh1 from both sides at the same time - but rather be coppelt together so that when one end shows Sh1 the other shows Sh0 and vis versa, but ofcourse both could showe Sh0 at the same time.

Thanks for the info Bob.
Certainly something I'll look into in the future.

thank you Bob, i will visit these
