Interesting flickering car lights

Just the way the rollers track. Convert to LED lighting with a capacitor and flicker will be eliminated.

use some goo gone and a q tip, make sure that your wheels are clean as well, and then check the small metal ground bar that goes across the wheels that it is making good contact

Rollers are for the middle rail, but you didn't mentioned if you clean the wheels too.

ground is very important too.

Still some minor flickering from some passenger coaches and cabooses only at low speed. Would the group say I really have nothing to worry about with flickering at low speeds?

Many thanks and Happy Holidays. 

Had exact same problem; cleaned the rollers and now....no "flickers" !!

Okay, before all the nay sayers jump in on this one, here is a little trick that will amaze you!

Wipe the collector rollers with a small amount of WD40 on the tip of a Q-Tip. Then wipe off the excess. Next do whatever you can to get WD40 into the bearings where the axle ends insert. (Unfortunately there is no way of wiping that excess off, unless you disassemble the truck, which pretty much defeats the purpose!).

Put the car back on the track and the flickering lights will disappear and stay on solid.

I have been using this trick for years and it is very effective! Lasts a couple of months before a new application is necessary.

If you don't agree, try it on one car! The results are quite spectacular!

Thanks,

Mike

What a good tip! Thanks I will try it. 

I was skeptical at first but decided to try this fix. Worked like a charm. Thanks Mike.   Joe

I noticed on K line cars the springs are prone to breaking. The rollers then just drag on the track bouncing up and down causing the lights to flicker. Changing these springs is a whole different story...
