We all lose a coupling or two or just the hooks in some cases, so it's handy to have some spares. I've been reading and hearing a lot about magnetic couplers and I thought I must buy some to try out. I have now used them on various RTR stock, to see how they cope. They are a wonderful detail to add to any buffer beam and when weathered they look even better. I have noticed some of the tiny magnets have come lose in there socket and stay stuck to the other side magnet. If so add a drop of superglue, close the coupler as normal and the lose magnet will slot into place. Pull them apart again to make sure no glue got anywhere it shouldnt and stick them together. Placing and taking stock off the layout is now a breeze. A simple but wonderful little detailing pack, to aid the ease of separating locos and wagons and add that small bit of extra realism to your rolling stock too.
