Probably, at least if you really want to go by train all the way. You can find other weird routes if you try, too. Teheran to Bangkok by train is a weird one.

Probably, at least if you really want to go by train all the way. You can find other weird routes if you try, too. Teheran to Bangkok by train is a weird one. You have to go west via Istanbul, then northeast to Moscow, then take the Transsiberian, then south through China, finally westwards to Bangkok. All possible but very convoluted and hardly something you'd do in order to reach the destination. In one way it reminds me of some friends of mine who went on a trip around the world for two months — on one airline ticket. The ticket was to New Zealand and back, with quite a few longish stopovers. Not the itinerary one would choose just to get to New Zealand.
