About a year ago there were a few postings (Picture from Lee W. below) on converting the couplers on the thomas cars and engines to Brio type magnets so young children could couple them up easier when setting up or recovering from a derailment. Lee W. was lucky enough to have some of the wooden train magnets to start with and then augmented them with well glued neodymium magnets.
I am about to start this project and was interested in the current state of the art on design ideas. Bigsmooth also mentioned in this post that he had found some good sources for magnets on line and in hobby stores. any references on where and what model magnets to get, which work best? Any design improvements since that original post? Thanks for any details and updates to this good project.
