China Train Types and Seat Classes Explained (2026)

Written by TravelChina's editorial team — a Singapore passport holder living in Chongqing since 2018 (8 years on the ground). I've personally ridden every train type and seat class listed below: G & D second class on the Chongqing ↔ Shanghai / Beijing / Xi'an / Chengdu corridors (60+ trips); G first class on Beijing–Shanghai (2024-11); G business class once on Shanghai–Hangzhou (2025-09, work expense); Z 软卧 Shanghai ↔ Lhasa (2019-08, 47-hour ride); K 硬卧 Chongqing ↔ Lijiang (2018-04, overnight); 硬座 Chongqing → Yichang (2018-06, 8 hours, cured me of the experiment). Sample prices below pulled from our verified data file routes.json (12306-sampled, refreshed monthly).

The 6 train-number prefixes at a glance

Every Chinese train number starts with a letter (or no letter), and that prefix tells you what kind of train it is. Here are all six prefixes plus the no-prefix "regular" service, ranked from fastest to slowest:

HSR family (G / D / C) uses one set of seat classes; conventional family (Z / T / K / 普客) uses a different set. The two families do not overlap on hardware or on what your booking experience looks like. Two deep-dive sections below cover each family in turn.

HSR family in detail (G / D / C)

HSR trains all run on dedicated electrified track, with a flat 80–90 dB cabin noise level (quieter than a typical airport terminal), passport-bound real-name booking and ticketless boarding via orange passport gates. The class hierarchy on G / D / C is the same shape; only the specific class options differ slightly by train.

Cabin amenities — same across all HSR (G/D/C): clean and quiet carriages, smoke-free (smoking has been fully banned on HSR since launch and is enforced with fines), modern lavatories at the end of every carriage, hot-water boiler in every carriage for instant noodles or tea, food-cart service every ~90 min (skippable), and — importantly — power outlets at every seat on basically every train except a few of the oldest Hexie units. The outlet is one of three locations depending on the carriage generation: under your own seat, between the front-row seats (in the gap), or on the back of the front seat near the floor. Plug type is the standard Chinese 3-pin (you'll need a travel adapter coming from US/UK/EU).

G trains — 350 km/h Fuxing CR400

The headline HSR product. Beijing–Shanghai, Beijing– Guangzhou, Beijing–Xi'an, Shanghai–Hangzhou, Guangzhou–Hong Kong via West Kowloon — all run G trains at 300–350 km/h. Hardware is mostly Fuxing CR400 rolling stock (the indigenous-design family from 2017+); some older Hexie still in service. G trains carry the full 5-class hierarchy: 商务 / 优选一等 / 一等 / 二等 / 无座.

From 60+ G-train rides Chongqing ↔ Shanghai / Beijing / Xi'an / Chengdu since 2018: the Chongqing North → Shanghai Hongqiao G2882 has been my baseline. 二等 ¥578 (most recent ride 2026-03), Wi-Fi via mobile signal patchy in tunnels, water boilers in every carriage, food cart pushed through the aisle every 90 min (skip the cart food and bring your own — Chinese travelers all do). Boarding window opens 30 min before departure; gate closes 2 min before. Late by 30 seconds and you're out.

D trains — 250 km/h Hexie / older Fuxing

The second tier of HSR. D-prefix trains run on the same dedicated track as G-trains in many cases but at lower top speed (200–250 km/h), or on overlap with mixed-use conventional–HSR track. Class lineup is more limited than G: most D trains carry only 一等座 + 二等座(no business class on the majority of routes), and 优选一等 (Premier First) is essentially absent because that's a Fuxing-only feature and most D trains are Hexie hardware. A handful of D services on busier corridors do offer 商务座, but assume 1st + 2nd class only when planning.

When D beats G: same route, ¥80–200 cheaper, 30–90 min slower. If you're flexible on time, the cost saving is real. Chongqing–Wuhan D train ¥255 vs G ¥358 (2025-11 ride), travel time 6h45m vs 5h35m — saved ¥103, lost 70 minutes.

C trains — short city-pair (城际)

C (城际, "intercity") trains are the commuter tier of HSR. Routes are short (30 min – 1 hour) and frequencies are aggressive. Top speed varies more than people expect: the older Beijing–Tianjin and the new Chengdu–Chongqing C lines run at 350 km/h(the same as a top-tier G), while Shanghai–Suzhou C trains run at 200 km/h. The seat-class lineup is usually 商务 + 一等 + 二等 on busier C routes (Beijing–Tianjin and Chengdu–Chongqing both have the full 3-tier offering); the smaller / shorter C lines may drop business class and run only 一等 + 二等. Common C corridors: Beijing–Tianjin (33 min, 12 trains/hour), Chengdu–Chongqing (1h15m, 143 trains/day), Shanghai Hongqiao–Suzhou (25 min, every 10–15 min).

For foreign tourists C-trains are the easiest HSR introduction — the journeys are short enough that even a first-time HSR rider can get the booking and boarding flow down in a low-stakes setting. I send first-time visitors on the Chengdu–Chongqing C train for exactly this reason.

Conventional family in detail (Z / T / K / 普客)

The conventional family is everything the HSR family isn't — older locomotive-hauled rolling stock, slower top speeds (up to 120–160 km/h), no dedicated track, and the use case is overnight long-haul or extreme-budget short-haul. The seat classes on conventional trains are 软卧 / 硬卧 / 软座 / 硬座 / 无座 — completely different from the HSR hierarchy.

Cabin atmosphere — meaningfully worse than HSR. Conventional Z/T/K carriages are 1990s/2000s design (the "25T", "25K", "25G" series in the official spec); cabin air is noticeably less fresh than HSR (HVAC is older, windows in 硬座 sections sometimes do open which helps but invites smells), the general fit-and-finish is dated, and the bathrooms are basic. Power outlets are limited or absent: 软卧 compartments usually have one shared outlet near the door; 硬卧 sections sometimes have a couple of outlets in the corridor; 硬座 carriages essentially have none accessible to passengers. Smoking has been formally banned on conventional trains too, but enforcement in the connecting areas between carriages (the "过道") is uneven — you may smell cigarette smoke drifting in, particularly on K trains. None of this makes the conventional family unusable; it just means an overnight Z 软卧 ride feels like a train-from-1995 rather than a train-from-2020. Bring a power bank and AirPods and you're fine.

Z trains — non-stop overnight (直达)

Z (直达, "direct") trains are the premium tier of conventional rail. Few stops between origin and destination, mostly run overnight, designed for the long-haul journeys where flying is the obvious alternative but the train ride itself is the experience. Famous Z routes: Beijing– Lhasa (Z21, ~40h), Shanghai–Lhasa (Z164, ~47h), Beijing–Shenzhen (Z107, ~24h), Beijing–Hong Kong (Z97, suspended in 2020, status varies).

Shanghai ↔ Lhasa Z164, 软卧, 47-hour ride 2019-08: the canonical "train ride as the destination" experience. ¥1,262 per berth in a 4-person compartment; passes through Qinghai Plateau (peak elevation 5,072m at Tanggula); cabin oxygen pressurized for the high-altitude segment. Food is served by a dining car (¥40–80 per meal) plus a hot-water boiler in every carriage for instant noodles. 95% of Western foreign tourists who do this ride do it specifically for the experience, not for the practicality.

T trains — express conventional (特快)

T (特快, "express") is one tier below Z — more stops, slightly slower, day or night service. Common for routes that have HSR alternatives but where T is significantly cheaper, or for routes that don't yet have HSR coverage (some Tibet, Xinjiang, and Yunnan interior corridors). T trains carry the full conventional class hierarchy.

K trains — fast conventional (快速)

K (快速, "fast") is the everyday conventional train. Many more stops than Z or T, slower (100–120 km/h average), the workhorse of regional travel before HSR was built out. Cheapest option that still has 软卧 and 硬卧 available. For foreign travelers the K-train use case is essentially: the route doesn't have a G or D yet, and flying is too expensive or your destination has no airport.

Chongqing ↔ Lijiang K117 / K118, 硬卧 2018-04: 24-hour overnight ride, mid-berth ¥244, smoking section between carriages was active (this was before the 2020 nationwide train-smoking ban tightened), carriage lights stay dim 22:00–06:00. Hard sleeper compartments are 6-berth and open (no door), so you'll chat with whoever's on the other 5 berths. This was how a generation of Chinese students moved across the country on summer break.

纯数字 / 普客 — slowest local (no prefix)

Trains with a pure-number designation and no prefix letter (e.g. train 5633) are 普客 ("regular passenger") — the slowest local stopping service. Rural routes, stops at every village station, fares as low as ¥1–5 per leg. Foreign tourists almost never ride these — they exist primarily for rural Chinese commuters and are a social-history artifact more than a tourist option.

All 9 seat classes explained

HSR seat tiers (G / D / C)

Five tiers, from premium to standing-only:

Worth-it guidance per HSR class:

• 商务座 — worth it on routes >4 hours when the cost is <8% of trip budget. Includes complimentary meal, lounge access at major stations, flat recline. Skip on sub-2-hour routes.
• 优选一等座 — only on Fuxing G trains. Pay it if you specifically want a wider seat without the full business-class spend. ~25% above 一等.
• 一等座 — the "photographer's class" — 2+2 layout means a guaranteed window seat, ~60% above 二等. Worth it on routes >6 hours or when window photography matters.
• 二等座 — the default. 3+2 layout, decent recline, comparable to international economy-plus. Window seats are the A and F positions; book early to secure them.
• 无座 — only book if the route is sold out and you have to travel that day. Same price as 二等 but no seat. Foreign tourists should generally avoid; re-book a different time slot or bump to 一等 if 二等 is sold out.

Conventional seat tiers (Z / T / K / 普客)

Five tiers, totally different concept from HSR — this is sleeper-vs-seat, not recline-tier:

Worth-it guidance per conventional class:

• 软卧 — the foreign-traveler default for any overnight conventional ride. Closing door means privacy; 4-berth means at most 3 strangers. Book the lower berth (¥30–50 more than upper) for easier access and a usable seat during daytime hours.
• 硬卧 — the right pick if budget is tight or if you want the social experience. 6-berth open, lower / middle / upper berths. Lower is best (full sitting room, easy access); middle is acceptable; upper requires climbing and you can't sit up. Cost 50– 70% of 软卧.
• 软座 — mostly phased out by HSR; still exists on a handful of T/K routes. Skip unless you're a railway nerd specifically wanting the experience.
• 硬座 — daytime 6–8 hour rides on a budget, sure. Overnight, no. The carriage lights stay on, the seats don't recline, and at peak holidays it gets standing-room crowded even with assigned seats.
• 无座 — same comments as HSR. Only buy if sold out forces it.

Decision flow — which to book

A pragmatic decision tree based on route characteristics. Pick the first matching scenario:

• Daytime, <4 hours, route has G or D → G or D 二等座. The default for 90% of foreign tourists.
• Daytime, 4–8 hours, route has G → G 一等座 if the budget supports it (~60% above 二等); otherwise 二等 is fine.
• Overnight, route has G or D ending in evening → book a daytime G/D + a hotel at the destination. Don't do overnight HSR — HSR network mostly doesn't run 23:00–06:00.
• Overnight, route is Z to a sleeper-only destination (Lhasa, Hong Kong via Z route, etc.) → Z 软卧 for comfort, 硬卧 for budget. Skip 硬座 for any overnight.
• Beijing ↔ Lhasa specifically → Z 硬卧 for the experience — the Qinghai–Tibet plateau ride is the trip. 软卧 if altitude sickness concerns you (closer to the cabin oxygen vent).
• Photographer wants window for sure → G 一等座 (2+2 layout = guaranteed window or aisle, no middle seat).
• Budget priority + short route → D 二等座 (typically ~30% below G for the same route, only slightly slower).
• You want the cheapest possible cross-country ride → K 硬卧 if overnight, K 硬座 if daytime. ~30–50% cheaper than HSR equivalent; travel time 2–3× longer.

Foreign-card payment notes are covered in our 12306 English booking walkthrough and Trip.com booking walkthrough — in short: 12306 takes some foreign cards via Alipay International rail; Trip.com takes Visa/Mastercard with a small service fee.

How to spot the type from a 12306 / Trip.com listing

Every Chinese train number starts with the type prefix (or no letter for 普客). On the booking apps:

• 12306 — the train number column shows the prefix as the first character (G15, D2287, C6017, Z164, K117, etc.). Filter pills at the top let you toggle "高铁/动车" vs "普通".
• Trip.com — train number similarly shown with prefix. Filters under "Train type" allow picking just 高铁 (G+D+C) or just regular.
• Klook — same train number prefix convention; filters slightly different naming.

So: when you see G15 in the listings, you know this is a top-tier HSR; when you see K117, you know it's a fast conventional, conventional class options apply.

FAQ

What's the difference between G and D trains in China?

Both are high-speed (HSR) but G is the top tier. G trains run 300–350 km/h on dedicated HSR track and operate the headline corridors (Beijing–Shanghai, Beijing–Guangzhou, Beijing–Xi'an). D trains run 200–250 km/h on slightly older or mixed-use track and cover regional and overlap routes. For the same city pair where both exist, G is faster and more expensive, D is slower and cheaper, hardware quality is comparable. Foreign tourists book G by default unless the time difference is small.

Is business class on a Chinese HSR worth it?

On a 4–8 hour route like Beijing–Shanghai (¥2,158–2,318) or Beijing–Xi'an (¥1,628–1,816) it's a comfort upgrade — flat-recline 2+1 seating, complimentary meal, lounge access, ~3× second-class price. On a sub-2-hour route like Chengdu–Chongqing (¥527–668) or Shanghai–Hangzhou (¥190–275) it's not worth it; second class for 75 minutes is fine and the budget is better spent elsewhere. Rule of thumb: business class makes sense above 4 hours of travel time and when the cost is <8% of your total trip budget.

Hard sleeper vs soft sleeper on a Chinese train — what's the actual difference?

Soft sleeper (软卧) is a 4-berth compartment with a closing door, individual reading lights, two upper and two lower berths, and ~50% more space per person. Hard sleeper (硬卧) is a 6-berth open compartment with no door, three berths stacked on each side (lower / middle / upper). Mattress quality is similar — 'hard' refers to compartment style, not the bed itself. Cost ratio is roughly 1.5–2× soft over hard. Foreign travelers usually pick soft sleeper for the door + privacy; hard sleeper is the budget-traveler default and a more social experience (you'll talk to your bunkmates).

Can foreigners sleep in the hard seat (硬座) overnight?

Physically yes, practically not recommended. Hard seat (硬座) is bench-style upright seating with thin padding; for an 8-hour daytime ride it's tolerable but for an overnight journey you'll be cramped, the lights stay on, and the carriage stays loud. I rode 硬座 once in 2018 from Chongqing to Yichang as an experiment — survivable but cured me. For overnights, even on the tightest budget, find ¥80–150 more for hard sleeper (硬卧). Foreign travelers planning Beijing–Lhasa or any 30+ hour ride should never book hard seat.

What's the cheapest way to cross China by train?

By train type: K (快速) and pure-digit 普客 (regular, no prefix) are the cheapest, often half the price of HSR for the same route. By seat class within those: 硬座 (hard seat) is the rock-bottom option. Trade-offs: K trains take 2–3× the travel time of HSR and stop frequently. Example: Beijing–Shanghai by K-train hard seat would be ¥158 vs ¥626 second-class HSR — but it's a 17-hour ride vs 4h18m. Most foreign tourists pick D second-class as the cheapest sensible option (~30% below G, only 1–2 hours slower).

Is there a difference between Fuxing and Hexie trains?

Yes, but for foreign tourists the practical difference is small. Fuxing (复兴号) is the newer indigenous-design family (since 2017), runs the 350 km/h G corridors, has slightly more legroom and the optional 优选一等座 (Premier First) class. Hexie (和谐号) is the older family (Siemens / Bombardier / Kawasaki–licensed designs from the 2000s), runs at 250 km/h, no Premier First class. Same booking system — you don't pick by name; you pick the train number and the system serves whichever hardware runs that route. Headline G corridors are mostly Fuxing now.

Do C trains have business class?

Yes, on the busier corridors. Beijing–Tianjin (350 km/h, 33 min) and the new Chengdu–Chongqing line (350 km/h, 1h15m) both run the full 商务 + 一等 + 二等 hierarchy on most departures. Smaller and shorter C routes (Shanghai–Suzhou, some regional commuter lines) often drop business class and run only 一等 + 二等. Worth-it logic is the same as for G trains: business class on a sub-2-hour C ride is hard to justify on price unless you specifically want the flat-recline seat — for most foreign tourists the 二等 is the default pick.

What does the train number prefix actually mean?

The first letter of the train number is the type code: G = 高速 (HSR top tier, 300–350 km/h), D = 动车 (HSR second tier, 200–250 km/h), C = 城际 (intercity, ~200 km/h, short routes), Z = 直达 (direct, conventional overnight, few stops), T = 特快 (express conventional, more stops than Z), K = 快速 (fast conventional, frequent stops, slow), pure digits / no prefix = 普客 (slowest local stopping service). The booking systems (12306, Trip.com, Klook) all show the prefix in the train number, so you can identify the type at a glance before buying.

Can I change seat class after booking?

Sometimes, with a change fee or by re-buying. On 12306 and Trip.com you can refund and re-book in a different class subject to the original ticket's refund rules (typically ~5% fee if >24h before departure, higher closer in). A faster path on the day of travel: if you want to upgrade and there are open seats in a higher class, find the on-train conductor (列车长 office is always in carriage 1, 8, or 16 depending on consist), ask for 补票升级, and pay the price difference. Downgrades work the same way but rarely worth doing for the small refund.

Which seat class do most foreign tourists pick?

Second class (二等座) on G or D trains, by a wide margin. The reasoning: HSR second class is comparable to international economy-plus or business-class on legacy European intercity trains; the 3+2 seating is comfortable for 4–6 hour journeys; the price gap to first class (~1.6×) and to business (~3×) is hard to justify for tourist budgets; window seats are bookable at the time of purchase. First class is a worthwhile upgrade for routes over 6 hours or when you want a guaranteed window with the 2+2 layout. Business class is for special-occasion budget or business travelers.

Are there power outlets on Chinese HSR trains?

Yes, on basically every G / D / C train except a handful of the oldest Hexie units. The standard Chinese 3-pin outlet is in one of three locations depending on carriage generation: under your own seat, in the gap between the front-row seats, or on the back of the front seat near the floor. US/UK/EU travelers need a travel adapter (no built-in USB on most trains). Conventional Z/T/K trains are the opposite story — power outlets are limited to one shared outlet near the door of soft-sleeper compartments and a couple in hard-sleeper corridors; hard-seat carriages essentially have none. Bring a power bank for any conventional ride.

What's the difference between a 无座 (standing) ticket and a 二等 (second-class) ticket?

Same price, no seat. 无座 (standing) tickets exist as overflow inventory — when every seated class on a train is sold out, the railway releases a small batch of standing tickets so people who must travel that day can still board. They cost the same as 二等 on HSR or the same as 硬座 on conventional trains. Always pick a seated option if available — buying 无座 saves nothing and you'll spend the ride standing in the vestibule between carriages. The exception: short C / D rides under 1 hour where vestibule standing is tolerable.
