GNR-Gordon-4, You obviously have an opinion on Hornby Live Steam and you may well be right. But I notice that you say that you don't own one. Have you actually experienced it, or simply gone on what someone else has said? Yes, they require a little more setting up and concentration while operating than DC or DCC, but that is part of their charm. With a little experience (and the right instructions), operation is not difficult at all. Clearly OO Live Steam is not for everyone, but anyone who puts in a little effort will be amply rewarded. Hornby were brave and visionary in bringing Live Steam to OO gauge and I thank them for it. Why it was not a commercial success, I don't fully understand, but I have a fleet of LS locos that prove that they were a technological success. I would encourage anyone who has one sitting dormant in the cupboard to dust it off and give it a proper go. For the record, I don't think Hornby will reintroduce them either, but there was plenty of development potential as people such as @gowest are proving (Live steam P2 with operating valve gear? - brilliant).
