Product Details

This neodymium magnet is purpose-made for replacing the weak magnet in certain model electric loco motors, such as Hornby Dublo 3-track (possibly other models too, eg Triang X03 & X04).

For a Bo-Bo loco, and possibly other models, use one of my D8x8mm magnets + steel spacing washers. I am likely to have a magnet suitable to rejuvenate most locos.
The original loco magnets were far weaker "ferrite" magnets, which grew even weaker over time, until the loco became unusable. Re-magnetising them had limited success. Neodymium magnets are the perfect solution. They are 10 times stronger than the originals, and don't weaken over time. They make a loco run fantastically, better than brand new! Replacement is simple, by removing a few screws. 

Size: 12.7mm x 9.5mm x 13.34mm rectangular block with a 2.4mm diameter mounting hole which is drilled through to the poles on the smallest faces

Quantity: 1 (Packs of 4 also available)

Grade: N45 Neodymium

Pole location:  Poles on flat faces

Pull/Push: Over 6kg when pulling directly to each other or a steel plate.


  • About 10 times more pull than the traditional, grey, ferrite type
  • This type of magnet never weakens with age
  • Triple plated for durability: Ni/Cu/Ni

Other Potential Uses:

  • Holders, eg for tools
  • School or University science projects
  • Clamp components while adhesive cures


  • Not for kids! Two or more, if swallowed, can lethally puncture gut tissue.
  • They can pinch skin and cut clothing.
  • The material is brittle. It can chip or break during collisions. Eye protection advised.
  • For credit cards, pacemakers etc, keep at a distance where the field is negligible.
