passenger car interference

I do not think they have a capacitor so I would say no. What causes problems is constant lighting circuits with capacitors. On those a 22uh choke in series should alleviate the problem. Having said that K-Line passenger cars with that stream lighting pull a lot of juice. In command up to 10 watts per car at 18-20 volts in command. The bulbs will also not last very long at that voltage and get pretty hot. I suggest converting to LED lighting or inserting a diode in series to the lights to dim them to half voltage. Alternate diode polarity between cars.

See LED lighting posts or dropping voltage with diodes here if interested

K-Line no. The problem cars are as follows.

1.Atlas caboose.
2. All Lionel 18 inch cars.
3. Atlas passenger cars.
4. Weaver passenger cars.
5. MTH rotary snow plow.
6. GGD passenger cars.--Scott recognized the problem and went to the LED board.
7. Lionel smoking caboose.

Off the top of my head these are the top ones. All K-Line cars are ok. Follow what Dale outlined and you will be OK.

Thank You!!

Has anyone found interference/signal degradation when using the MTH EOT device. It seems to affect my signal quality.

I confirmed it actually. When I run the train that has the EOT device my command responses are slow and/or duplicated. Put the car with the EOT device on an unpowered siding and reactions are better.

Could be just a coincidence but I did try the experiment twice.

Walt;
Have you contacted MTH about this? I suspect you have a defective EOT.

I've an Atlas caboose with the flashing rear light. Is it supposed to cause some sort of problem?
What sort of problem?

Don't notice any ... maybe lucky?

The Atlas caboose with the flashing light it a known problem for the DCS signal. Typically you will not be able to add engines and may have difficulty controling them withan unmodified caboose on the track. Dale's suggestion above should cure the problem.

Marty,
Does the problem apply to all Weaver passenger cars? I have an older set, and don't remember ever having an issue...

Here is a link to suitable chokes for car lighting.

I am wondering why alternate the polarity of the diodes between the passenger cars?

Thanks,

Rick

I'm not having any trouble out of my caboose either(Watch it LOL)
Or my Lionel 18 inch Passenger cars.

I guess I ought to go play the Lotto . I've never bought a ticket before but if I'm this lucky?

Since you are half waving the cars with a single diode,Only half of the AC sine wave is used to power it. Altering polarity,one car would use the top half of the sine wave and the other car would use the bottom half. Not good on the transformer to use all of one side. Also in conventional if a lot of cars were run off one side,enough voltage drop could occur on one side to trigger the bell or whistle. On a 5 car set,3 one way and 2 the other way is OK. If LED lighting is used,it pulls such little power that this would not be an issue,but light bulbs use considerable current.

If you use 2 diodes per car,one from each roller pointed in the same direction (toward the bulbs or away from the bulbs) you get the added protection to the wire connecting them in case a derailment occurs where one roller is on the center rail and one roller is on an outer rail. Current will not flow through opposing diodes.

Thanks Russell. I will take it to April York and see what they say in the MTH parts booth.

Dale H: thanks for the answer.

No interference with 8 MTH Premier Amtrak rib side passenger cars and 2 engines, All 10's all around the track. Same when parking the passenger cars on a connected reverse loop.
