As many of you intermodal fans/modelers know each mfg has created a proprietary container attachment system for their containers only. For Modelers, this is annoying because a modeler either has to focus on one mfg's containers or limit the different containers to that mfg's intermodal equipement.
I would like to know if many have thought of a cheap way of an O guage universal container attachment system.
I was considering implanting those N50 magnets on the bottom of the model container's corner castings. Any MTH or other mfg's containers that have pegs for holders would have those pegs chopped off/sanded down and rely on the magnets implanted in each corner casting. What do you think? how should they be mounted- all positive magnetic sides facing down and negative magnetic sides facing up?
