Can I take a large suitcase on the high-speed train?
Short answer
Within limits, free: 20kg per adult, and on high-speed trains each item's three dimensions may total no more than 130cm.
The numbers on the official page
The railway's free cabin allowance is 20kg per adult passenger, 10kg for children and 35kg for diplomats. Dimensions are per item: a total of three sides up to 160cm on conventional trains, but only 130cm on the high-speed EMU sets, with rod-shaped items allowed up to 200cm.
That 130cm figure is the one that surprises people, because it is tighter than the airlines' usual 158cm checked standard. A big checked-size suitcase can be legal in the air and over the line on the rails.
Compare the trap with Japan's
Japan's shinkansen rule is about reservation — over 160cm you book a luggage space, and the bag still rides. China's rule is a size ceiling on the high-speed sets, with no reservation mechanism to buy your way past it.
So the same big suitcase produces two different problems on the two networks: a missing booking in one country, an oversized item in the other.
If your bag is over
The practical answers are the ones the railway itself operates: consign the bag as luggage where the service exists, or use the door-to-station Easy Travel service at the major stations and let the bag travel separately.
For a trip built around the high-speed network, the honest packing advice is a suitcase that fits the 130cm total — the limit is per item, so two medium bags beat one huge one.
Good to know
- 130cm total on high-speed trains — tighter than airline checked-bag sizing
- The limit is per item: two medium bags beat one huge one
- 20kg free allowance per adult
Yes, but once the three sides added together pass 160cm you have to reserve the space in advance.
