Change red/blue magnet on old wagons?

[bmassaer]

Hello,

I have these old wagons with the blue and red magnets for coupling. Unfortunately, some of these magnets are broken. Can they be replaced? How is it done?
I found this on Brickscout: https://brickscout.com/nl/products/detail/4059217042231
Is this the part I need to replace them? 

Thank you,

Bart

No, those are not the correct magnets, they're the ones used on cranes. The correct ones are these;

Unfortunately it is quite common for the magnets to break and the wagons are not worth much without the magnets. You might be better off by buying a few wagons with one good magnet and use them to repair your ones. Be careful taking the magnets off, they require a bit of force, and it can be easy to break them.

OK, thank you for this advice. But I still find it difficult to "throw away" the wagons without magnets. I tried a setup with the black magnet-holders, but they always seem to be fitted a little too high, so it does not really work, unless I make a strange contstruction to attach them.
