a body (and cylinders. Failing the correct one, I have an Airfix one and a collection of Kitmaster/Airfix bits. To get things started a few notes on my favourite Peco/Dublo/Trix/ Playcraft/Jouef coupling. These are quite reliable and have the great advantage of it being easy to remove/uncouple a vehicle just be picking it up, unlike the Tri-ang type (and associates) which always manage to tangle up. It is, however, prone to random uncoupling. This can be alleviated if attention is paid to the following points: All couplings must be at the same height (about 10mm - the correct dimension will be something Imperial in thou.). I keep an unmolested HD vehicle and ensure everthing else will operate correctly with this. In addition, I have built a gauge from plastic sheet for setting the height, which, incidently, is the same as Kadees and the X2f American H0 couplings (They will couple (but not uncouple - the uncoupling ramps are different -  wthl X2fs, but not Kadees). This also enables the dropper height to be set. The specification is 1/32" above rail level, but I feel that this is a minimum and it is not important if it is a little higher - as long as it contacts a raised uncoupling ramp. It is important that it is vertical to obtain the correct movement of the coupling to uncouple reliably. (There are two types of uncoupling ramp Dublo and the narrower Trix variety. They will couple reliably but the wrong ramp will
