You’ll often hear the advice to book China train tickets as early as possible. But does that really apply to every train journey in China — including extremely frequent routes such as Shanghai to Nanjing?
One traveler questioned that blanket advice and asked the ChinaTravelBUG AI Travel Planner whether some Chinese train routes can be booked more flexibly.
The Traveler’s Question
Hello! Do train tickets for the route Shanghai-Nanjing sell out quickly?
I know many suggest to book in advance, but there are trains every few minutes for this route, so I wonder if the rule to book as early as possibly applies evenly on ALL train routes in china, or for other specific categories (longer routes, public holidays ecc).
Thank you!

No — the advice to “book China trains as early as possible” doesn’t apply equally to every route. Shanghai–Nanjing is actually one of the routes where I’d be much more relaxed.
The reason is exactly what you noticed: capacity and frequency matter enormously. Shanghai–Nanjing is an exceptionally busy high-speed rail corridor with many departures throughout the day. China Railway even uses flexible pricing on the Shanghai–Nanjing intercity line, reflecting the range of trains and travel times available. (12306)
For Shanghai → Nanjing
On an ordinary weekday, I would not feel compelled to grab a ticket the moment sales open simply because somebody says all Chinese trains sell out.
What can disappear first are the most attractive trains: convenient morning departures, faster services, the departure station you prefer, and especially second-class seats.
So there’s an important distinction:
“There will probably be a train available” ≠ “my ideal train will be available.”
If your Shanghai hotel is booked and you already know you want, say, an 8:30–9:30 departure, there’s little benefit in deliberately waiting. Book it when convenient. But if your sightseeing plans are still fluid, Shanghai–Nanjing is one of the routes where that flexibility has real value.
Where I would book early
I’d be considerably more cautious with:
- Major Chinese holidays, especially Chinese New Year/Spring Festival, National Day and other peak travel periods.
- Friday evenings and Sunday returns, particularly around large cities.
- Long-distance trains with relatively few departures.
- Sleeper trains, where the particular berth type you want may have limited inventory.
- Routes with only a handful of useful trains per day.
- Any journey where missing that particular train creates a serious problem — an international flight, fixed tour, cruise, etc.
China Railway’s official booking channel is 12306, and tickets are tied to a specific train rather than functioning like an open ticket. (12306)
So I’d replace the blanket rule “always book Chinese trains immediately” with:
The fewer acceptable alternatives you have, the earlier you should book.
For Shanghai–Nanjing, you usually have lots of acceptable alternatives. That’s very different from needing one particular long-distance train on a peak travel day.

Editorial Verification Note
Train frequency, schedules, fares and seat availability can change. The Shanghai–Nanjing corridor is one of China’s major high-speed rail corridors, but travelers should always check the actual services available for their intended travel date.
For current schedules, ticket availability and booking information, check China Railway’s official 12306 platform.
The practical principle in this answer is more important than applying a single booking rule to every journey: the fewer suitable alternative trains you have — or the more important a particular departure is — the more valuable early booking becomes.
