Train travel · China

Hi everyone,

I’m planning a family trip in a year. Our goal: traveling to China (and maybe Hong Kong) by train. I’m all set with the route up to eastern Turkey. However, I’m just starting my research for the rest of the journey—namely the Caucasus (no trains as far as I know, so buses and/or ferries), then Central Asia and China. So, I’d love to hear any info or tips (general and forward-looking at this stage) about the train route through Central Asia and China to reach the east coast. I’m particularly interested in details on: - How far in advance to book / any potential difficulties with reservations - Whether there are PASS systems (or equivalent) between countries and/or if some tickets allow stopovers, meaning you can hop on and off as you please - Day trains vs. night trains (the latter option lets you explore cities between two legs of the journey) - A rough idea of ticket costs ...

A huge thank you to anyone who can share some info or experiences. It’s also a great opportunity to chat about adventure after (way too) many years away from this forum.
