I'm flying into Tashkent then getting the train to Sarmakand, from there it's a short camel treck north before doing the last leg by bike. The way home is a bit more simple, going on horseback to Prague, then getting a taxi back to Liverpool. Hadn't heard about that direct train though mate - might want to check that out? I've got a couple of spares for this, but I'd have to meet in Iran, and will only swap them for three geese eggs.
