The issue about steel weights over uncoupling magnets is a non-issue until it happens to YOU. I've learned (don't ask me how!) the following:
- HO scale cars such as Athearn that use steel weights. Rarely a problem. You have to have both very free rolling trucks and a very powerful magnet. Usually, the accidental uncoupling is shrugged off or the magnet removed, unless you hapen to notice that it's always the same car.
- N cars with steel weights. Often a problem as soon as you replace the trucks or wheels with something that is free rolling. My best guess is the distance of steel weight to the magnet is the primary factor, with inertia of the car (related to weight) being a secondary factor.
- HOn3. Haven't run across any cars with steel weights yet. I expect problems similar to N.
- Lionel. Once, using a higher than normal voltage on the uncoupling track, I watched a free rollling light weight operating car (with the iron plunger in the center) center itself over the uncoupling magnet.
Cures include:
- Not using permanent magnets for uncoupling. However, the problem can foul up delayed uncoupling with electromagnets or pivoting permanent under the track magnets, too.
- use something besides iron or steel to weight your cars. But removal after the fact can be quite difficult - tank cars come to mind.
- don't use free rolling trucks. However, this impacts train length and the number of cars a loco can pull.
- use rare earth magnets mounted vertically beside and just outside rails, staggered slightly is even better. The increased distance and the non-centerline component of the magnetic force on the car weight seem to cure the problem.
my thoughts, your choices

For the newbie's,
With added weight, metal wheels will really help those car track a lot better.

Nickels are bigger than pennies and bigger is better. You like to add more than 2ยข worth. You like Jefferson's profile picture more than Lincoln's. You prefer the profile pictures that face left rather than to the right. You like Jefferson's house more than the Lincoln Memorial. You prefer metal alloys over pure metals. You think 3rd is a higher ranking than 16th. Jefferson was the 3rd president and Lincoln was the 16th. The Jefferson nickel has been minted since 1938, the first Lincoln penny was issued in 1909, the 100th anniversary of Lincoln's birth and you think newer (1938) is better than older (1909). You prefer "E PLURIBUS UNUM" a the top of the coin. You think "A penny for your thoughts..." sounds cheap. Your rich and don't know what to do with all your nickels. [:D] [:D] [:D] [:D] [:D] [:D]

QUOTE: Originally posted by mark_in_utah For weight I've been using shotgun shot and mixing it with white glue mixed with water and alcohol. I was able to get 10 pounds of the stuff for less than $10. You can get it in lead or steel, and it's a LOT cheaper by the pound than BB's. For the best load density you want the smallest shot (largest shot number). #8's or 9's are good. As for the dangers with lead, lead is "safe" as long as you don't ingest it! Make sure you thoroughly wash your hands after using it. The proper weighting of cars is important in getting reliable operation of your cars. As I remember the rule of thumb is 1 ounce plus 1/2 ounce per inch of car weight for HO scale cars. For coal cars, the best I've found is filling the car with coal and gluing it in place with the white glue mizture. What's better in modeling a coal train than hauling actual coal?? It makes the cars heay, but is that so bad? Mark in Utah
QUOTE: Originally posted by AntonioFP45 What problems are you having with the Kadee track magnets? Basically, cars loaded with steel metal weights shouldn't interfere with the magnet at all if the weights are secure, be it flat or ball bearing. Could you give us some details please? I would like to know of any potential problems.
