What s the difference between LEGO s buffers and US couplers?
From John Neal: ! The LEGO design combines the buffer and the coupler. US train trucks do not have buffers. In fact, one way to convert the LEGO design is to cut the buffers off. From Ben Fleskes: ! The hole in the plate accepts the train coupling, eliminating the buffers. To get the height right, simply put the magnet holder in from the top or the bottom.
