Korail2 (with N-card discount support)

A fork of korail2 with added support for KorailTalk N-card discounted tickets.

The original korail2 project appears to be no longer actively maintained, so this fork was created to keep the library working with the current Korail API and to add N-card discount functionality.

Added on top of the original project:

• Query owned N-cards (owned_ncards)
• Search discounted trains with an owned N-card (search_owned_ncard_trains)
• Build N-card reservation payload (build_ncard_reservation_payload)
• N-card usage history (ncard_history)
• KorailTalk dynamic auth token generation (DynaPathMasterEngine)
• AES-encrypted login

Installing

Not published to PyPI. Install from source:

$ git clone <this-repo-url>
$ cd korail2
$ pip install -e .

Or install dependencies directly:

$ pip install requests six pycryptodome

Using

1. Login

First, you need to create a Korail object.

>>> from korail2 import *
>>> korail = Korail("12345678", YOUR_PASSWORD)          # with membership number
>>> korail = Korail("[e-mail]", YOUR_PASSWORD) # with email
>>> korail = Korail("010-9964-xxxx", YOUR_PASSWORD)     # with phone number

If you do not want login automatically,

>>> korail = Korail("12345678", YOUR_PASSWORD, auto_login=False)
>>> korail.login()
True

When you want to change ID using an existing object,

>>> korail.login(ANOTHER_ID, ANOTHER_PASSWORD)
True

2. Search train

You can search train schedules with search_train and search_train_allday methods.

• search_train returns up to 10 results. Faster than search_train_allday.
• search_train_allday returns all results after the given time. Calls search_train repeatedly.

Both methods take these arguments:

• dep : A departure station in Korean ex) '서울'
• arr : An arrival station in Korean ex) '부산'
• date : (optional) A departure date in yyyyMMdd format
• time : (optional) A departure time in hhmmss format
• train_type: (optional) A type of train. Use TrainType class constants. Default: TrainType.ALL.
  • TrainType.KTX — KTX / KTX-산천
  • TrainType.SAEMAEUL — 새마을호 / ITX-새마을
  • TrainType.MUGUNGHWA — 무궁화호
  • TrainType.NURIRO — 누리로
  • TrainType.ITX_CHEONGCHUN — ITX-청춘
  • TrainType.AIRPORT — 공항직통
  • TrainType.ALL — all types
• passengers: (optional) List of Passenger objects. None means 1 AdultPassenger.
• include_no_seats: (optional) When True, results include sold-out trains.

>>> dep = '서울'
>>> arr = '동대구'
>>> date = '20260512'
>>> time = '100000'
>>> trains = korail.search_train(dep, arr, date, time)
[[KTX] 5월 12일, 서울~동대구(10:00~11:43) 특실,일반실 예약가능,
 [KTX] 5월 12일, 서울~동대구(10:30~12:05) 특실,일반실 예약가능,
 ...]

2-1. About the passengers argument

passengers is a list (or tuple) of Passenger objects. Supported types:

• AdultPassenger — adult
• ChildPassenger — child
• ToddlerPassenger — toddler (동반유아 discount)
• SeniorPassenger — senior (경로 discount)
• NCardPassenger — N-card discount (see N-card section below)

# 1 adult, 1 child
>>> psgrs = [AdultPassenger(), ChildPassenger()]

# 2 adults, 1 child
>>> psgrs = [AdultPassenger(2), ChildPassenger(1)]

# 2 adults, 1 child, 1 senior
>>> psgrs = [AdultPassenger(2), ChildPassenger(), SeniorPassenger()]

# 1 adult, 1 toddler
>>> psgrs = [AdultPassenger(), ToddlerPassenger()]

# then search or reserve
>>> trains = korail.search_train(dep, arr, date, time, passengers=psgrs)
>>> korail.reserve(trains[0], psgrs)

3. Make a reservation

>>> trains = korail.search_train(dep, arr, date, time)
>>> seat = korail.reserve(trains[0])
>>> seat
[KTX] 5월 12일, 서울~동대구(10:00~11:43) 42500원(1석), 구입기한 5월 8일 14:05

Multiple passengers:

>>> seat = korail.reserve(trains[0], passengers=psgrs)

If seats are not available for the number of passengers, SoldOutError is raised.

To select seat grade priority, use ReserveOption:

• GENERAL_FIRST — economy before first class (default)
• GENERAL_ONLY — economy only
• SPECIAL_FIRST — first class before economy
• SPECIAL_ONLY — first class only

>>> korail.reserve(trains[0], psgrs, ReserveOption.GENERAL_ONLY)

To join the waiting list when sold out:

>>> korail.reserve(trains[0], psgrs, try_waiting=True)

3-1. N-card discounted tickets

N-card support is based on static analysis of the KorailTalk Android API. Payment automation is out of scope — this library covers train search and reservation payload construction only.

List owned N-cards:

>>> cards = korail.owned_ncards()
>>> cards[0]
[N카드] 대전~서울 0012345678-20260101-001-1234
>>> cards[0].discount_card_no
'1234567890123456'

Search discounted trains with an owned N-card (mirrors KorailTalk "My Ticket > Pass > N-card > Ticket booking"):

>>> trains = korail.search_owned_ncard_trains(
...     cards[0],
...     dep='대전',
...     arr='서울',
...     date='20260512',
...     time='100000',
...     train_type=TrainType.KTX,
... )
>>> trains[0]
[KTX] 대전~서울(10:00~10:57) 9900원 15%할인
>>> trains[0].discount_name
'15%할인'
>>> trains[0].general_remaining_seats
'023'

Build a reservation payload (complete final payment in the official app/website):

>>> payload = korail.build_ncard_reservation_payload(
...     trains[0],
...     ncard_no=cards[0].discount_card_no,
... )
>>> payload['txtDiscKndCd1']
'153'

If Korail only allows immediate payment/issuance for a discounted ticket, complete the final step in the official app or website.

N-card usage history:

>>> history = korail.ncard_history(cards[0].discount_card_no)

search_ncard_trains is retained for N-card kind/product schedule research when you already have the raw card metadata. For booking with owned cards, prefer search_owned_ncard_trains.

4. Show reservations

>>> reservations = korail.reservations()
>>> reservations
[[KTX] 5월 12일, 서울~동대구(10:00~11:43) 42500원(1석), 구입기한 5월 8일 14:03,
 [무궁화호] 5월 12일, 서울~동대구(10:30~14:15) 21100원(1석), 구입기한 5월 8일 14:03]

5. Cancel reservation

>>> korail.cancel(reservations[0])

6. Get tickets already paid

>>> korail = Korail("12345678", YOUR_PASSWORD, want_feedback=True)
>>> tickets = korail.tickets()
>>> print(tickets)
[[KTX] 5월 10일, 동대구~울산(09:26~09:54) => 5호 4A, 13900원]
