A real easy upgrade.

The motor bogie of my refurbished Triang DMU couldn't pull the skin off a rice pudding. Give it a prod it would run a few inches and stop and it was sending the ammeter way up the scale, so I figured everything else looking OK it had to be a duff magnet, it has to be around 50 yrs old, so I can't complain to much.
Anyway I decided to test it with a couple of neodymium magnets I just happened to have. Vast improvement. The magnets have so much grip they are unlikely to move of their own accord, so I decided not to bother trying to get a 9.7mm cube one with a hole running in the direction of the field.
The fitting instructions are easy.
Stack the two magnets N to S.
Determine which way they repel as you offer them to the chassis.
Push then into position until they snatch onto the pole pieces. That's when the Alnico magnet that's fitted gives up.
Job done, they won't be moving anytime soon.
Performance much improved, I could be on the lookout for a centre car, now there's a chance of pulling it.
