there are specific reasons why.

a.) is your layout analog or digital
b.) if it is just on one spot it is not a short
c.) if you would have a short in the track no loco would run anwywhere
d.) what type of tracks are you using.
e.) make sure all wires brown and red are connected and there are no loose connections.
f.) make sure the track is clean.
g.) do the loco stop at the same spot all the time ?

...re-clean...then re-verify the connections...
Then re-reclean....re-reverify the connections ...
Then...re-re-re-clean....re-re-re-verify....
(including the center spikes from the third rail)
etc....
(" re-re-re-re"....ect : it happens to me already)
What happens with a light bulb connected between 1 rail and 1 center stud ?...
are the track well flat...? ...no play ?
Is there a loosen insulator somewhere ?...

1. In some tracks it happen in he middle at others at the connection point it's not consistently
2. it's seems strange but it's stops on the track if I move the loko a few cm on the same track it's start working.
3. I dont have a voltage meter and I didnt test the voltage on the track but I will buy one tomorrow.
4. at some places on the layout if the loko drive slowly it will stop if on the same place I will increase the speed the loko will pass the track again also on high speed it can stop.
5. I don't have a booster my layout is 2.00m long X 1.00 Width 2 X circles (2 parralel) I'm using cs 60652 with 18 VA trasformer

It worked perfect for 2 months till last Monday.
Can you give me more details about the booster catalog no, output...etc

I think you need to determine if the short is in the track, is it being caused by a wagon or engine or is somehing else going on. So I would start with running just one engine around the track and seeing if the short happens. You said it happens at one point in your layout, is a slider on the engine making contact with the outer rail and center rail at this point? Is it a turnout? If the Engine runs around your layout fine then I would look at the passenger wagons as mentioned in the previous post, if they have a slider for interior lighting they could cause a short. If you can't run any of your locomotives around the track without things shorting out I would suggest you disassemble your c track and as you reassemble it run an engine on the track as you add sections to see where the short is. You should be able to add more and more track until you hit the problem. I hope this helps.

Michael,

Couple of question if I may. Some people 'think in pictures' (if you know what I mean), I am one of them, so whatever you describe I can only relate to by forming an image in my mind. Usually for me it's a good thing. Sometimes, it's a pain, like when you hear certain noises that instantly conjure up an image - people using the bathroom is a good example.

But I digress, (just a little).... what I'd like to know is you say it's a C-track double-oval, so have you built it from a plan, perhaps from a starter-set instruction sheet or from a catalogue, are you able to post an image of the plan, or a photo of your actual layout and indicate where the loco stops?

The other thing is that you say it ran fine until just recently and the problem was immediate, rather than getting gradually worse.

If you were using M or K track, we would have a much wider range of possible causes, but C-track rules out many things so the sudden stopping of your loco at the same point every time means a loss of power. Either to the TRACK at that spot, or to the SLIDER (or wheels) at that spot.

You say if you push the loco a short distance it runs again? How long is a 'short distance',? one complete track length, or how many sleepers?

Is there a track join right where it stops? Is it on a turnout, detection track etc?

If the slider (pickup) is losing contact, it could be getting lifted up by some interference? (something foreign stuck around the studs)

If you can't easily get a multimeter, you could at least get a normal 12-16v lamp with two wires and check the power to the outer rails and the center studs?

You also said at the start that you 'changed the track' - does this mean you removed the section where it stops and substituted another in its place?

Your previous postings indicate you have more than one Loco, do they all stop at the same spot or just one?

If nothing seems to work, do you live anywhere near another forum member who might be able to assist? (your profile does not indicate where in the world you are).

Thank you all for the detailed answer I think that one of the answer was the solution for the problem. I clean the tracks very well and it's start working again I think that humidity was the reason to the problem.
again thak you all for the answers
