Fitting Kadee couplings to Hornby HST power cars

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.

Adding Kadee couplings to Lima Mk3 coaches

It’s very simple to convert Lima Mk3 coaches to use Kadee couplings. Just cut off the huge tension lock leaving a tongue of plastic and glue a Kadee number 20 coupling onto the top of this using Evostik Impact adhesive. Adjust the length of tongue and the positioning of the Kadee so that the coupling knuckle is correctly just proud of the corridor connection.

A similar approach can be used with Hornby (ex Lima) Mk3 coaches but the number 20 is glued into the existing pocket with its tail suitably shortened.

Once the glue sets this arrangement will easily take the load of a full length train being pushed or pulled and will navigate second radius curves.
