Hey all, I need a few Shurlock/Shurlette Holmes out there. I am running the analog M track with digital locomotives. I have a Marklin 6001 transformer powering my tracks and turnouts and a Marklin Mobile Station 2 (60653) running the locomotives. Every time I put the locomotives on the track, the 6001 pings and the lights on the switches go out. Every time I take the locomotive off, the lights come back on. Chased the wiring, it looks fine. Pulled each switch off one at a time just to make sure one was not shorting out the track...still got Ping!/lights out after each disconnect. Finally, I disconnected the 6001 from my layout, took one piece of straight feeder track (5111) and ran it to the transformer by itself. I put the locomotive on that....just ping! this time as I had no lights. So, I have narrowed it down to the 6001 transformer and the locomotive. Here comes the weird thing. It worked fine this summer. I programmed all three of my locomotives into the mobile station and it worked fine. So, anyone can think of what I have done wrong. I did the digitizing of my locomotives. They worked and now they don't. Going to keep at it as I have eyes on the situation. Any new thoughts would be appreciated. Thanks for your time.I
Thomas ( I am nooo expert at this stuff/learning stage so this is probably a dumb thing. it is just frustrating)

Dear Thomas,
I have no idea what the error could be. I think I need more details how use wired things up.
Is the 6001 used for both lights and switches and MS 2?

Ah, there goes our digital expert again.
What is a 66130? The output of 66360 is 18 V DC, not 19 V DC.
The MS 2 can use the track boxes 60112, 60113, 60116, or 60114. The track boxes can be used with 16 V AC.

In the Märklin world we have "red" and "yellow".
"Red" comes from the MS 2 track box and should go to the centre rail only - and nothing else should go to the centre rail.
"Yellow" comes from the 6001 and goes to switches and lights.

"Brown" comes from the MS 2 track box and from the 6001. Both browns can be connected and in some setups they must be connected.

Note: When the 6001 is used to power the MS 2 track box, then you must not connect anything else to the 6001. In this case it will be harmful to connect brown from the 6001 and brown from the MS 2 track box.

There must be only one power source for the centre rail (red).
But sometimes you need a common ground (brown) between the MS 2 and the accessories transformer (your 6001).

If it worked in the Summer, then something must be different now.

Hi, I don't quite understand your installation, but I'll try to clarify some concepts.
There are no analog M tracks, märklin has or has had 3 types of tracks, M, K and C, any of them can be used in analog or digital, they are simply tracks.
Is it possible to run locomotives in digital and turnouts in analog? yes it is possible, for that:
The locomotives through the track will be managed by a digital control like the MS2, only this MS2 must be connected to the track (red and brown wires).
The turnouts and accessories (yellow and blue wires) will be connected to a transformer and the corresponding switches.

Märklin has published online several documents explaining the connection possibilities, usually come in the starter packs, look for any of them

here they are in Spanish, in English you can also search for them.

Best regards

Relax!!!
Leave out of your agenda.
I did wrote wrong number of the power feeder.
In fact does power shows between 18-19 VDC by use 66360.
TS...i recommended you by follow Märklin recommended use power feeder 66360 for the box 60116 when you use MS2.
Use 6001 trafo for the lighting or something else.

if the OP says that "The Mobile Station is a recent purchase, so this summer, I made an oval and programmed my locomotives into Mobile Station 2 . It seemed to work fine." I assume that the oval was an isolated piece of kit.
Today he is trying to merge the 6001 and MS2 stuff and the information provided above is correct.
I have the same situation, analogue equipment and digital trains. My vintage stuff, 7186 and 7051, are powered by a white transformer and the locos and switches by my EcOS.

try programming on a short isolated piece of track

Ben, Thanks for the reply. I have done that. I think I have a ghost in the machine as the mobile station is acting up. I am going to try and reset it today. My display is breaking up a bit and unfortunately, I live in Korea so I do not have anyone near me who can update with another Marklin accessory as they can not be updated from a computer. Long story short, if I can not get this to work. it will be taking a vacation to the states where a friend can try and get it right.
