This is the busiest single leg on most first China itineraries, and the rail connection is good enough that flying it is close to a mistake.
The journey#
G trains run Beijing West (北京西站, Běijīng Xī Zhàn) to Xi'an North (西安北站, Xī'ān Běi Zhàn) in roughly 4h20, with the quickest scheduled services a few minutes over four hours ten. Departures run from early morning to evening and there are many of them, so this is not a train you need to build a day around.
Slower D services and overnight conventional trains also cover the route and take considerably longer. Unless you specifically want a sleeper, take a G.
The two stations#
Beijing West is an interchange for metro Lines 7 and 9, which share a platform — you step off one and onto the other. It is not Beijing South and it is not Beijing Station, both of which serve different lines; check which one your ticket names.
Xi'an North is on the metro too, and the ride into the walled old city takes well under half an hour. Almost everything a visitor wants in Xi'an is inside or just outside those walls.
Why not fly#
Two and a half hours in the air looks faster until you add the rest. Beijing's airports and Xi'an Xianyang are both a long way out, domestic flights in China are delayed routinely rather than exceptionally, and you would spend two hours at the departure end before boarding. Door to door the train is usually ahead, and it is ahead reliably rather than on a good day.
The general rule is train under five hours, fly beyond. This leg sits comfortably inside it.
Fitting it into a trip#
Beijing to Xi'an is the classic second leg. Three or four nights in Beijing, then Xi'an for the Terracotta Army, the city wall and the Muslim Quarter, then onward to Chengdu (3h by rail) or Shanghai (6h).
Two things worth knowing before you book:
- Book as early as the window allows. Popular departures on this route sell out, particularly around holidays, and there is no standby.
- Give the station 30 minutes, not the two hours an airport needs — but not five minutes either. Security, ticket check and finding the right waiting hall take longer than they look in a station this size.
Xi'an itself rewards two or three nights. The Terracotta Army is a half-day out at Lintong rather than a city sight, so plan it as a block rather than slotting it between two others.
