The highly detailed Hornby HST power cars have a NEM pocket but it is fitted far too low to use with regular push-fit Kadee couplings. To get around this take the supplied tension lock coupling which has the necessary height offset built in and ‘cut and shut’ this with the working part of a Kadee NEM coupler. Once the spacing is worked out it is possible to join the two plastic parts using a soldering iron to carefully ‘weld’ them together. The cut off tail from the Kadee can be used to melt in some additional re-inforcing plastic to keep the coupling at the correct height. Once done this will easily permit pulling or pushing of a full length HST set.
