What they up to now, the 4th rewrite of XpressNet protocols? Oh well I guess they'll get it right eventually. I think they should call it HalfNet, since it's missing half of it's functionality... still. Cut out the middle man and let the decoders comunicate directly with the throttles, ah LocoNet, peace of mind and future proof, and doesn't need constant upgrades and protocol rewrites like that XpressNet junk. Well that's just sunk Hornby's system into the bottom 10% hasn't it.
