Basic Information

Have started servicing the public on July 2nd, 1985 along the branch of the famous Trans-Siberian Railway, K23/24 is the second pair of trains connecting Beijing and Ulaanbaatar after K3/4. It is operated in cooperation between China and Mongolia. The train operated by China has 16 carriages, including 9 hard sleeper carriages, 2 soft sleeper carriages, 2 deluxe soft sleeper carriages, 1 dining carriage, 1 luggage carriage and 1 dormitory carriage. Before leaving China in Erlian, the dining and dormitory carriages and 2 hard sleeper carriages will be unloaded. After entering Mongolia, a Mongolian dining carriage and a dormitory carriage will be joined on. The Mongolian train is equipped with 17 carriages: 10 hard sleeper carriages, 3 deluxe soft sleeper carriages, a luggage carriage, a dormitory carriage, a dining carriage, and agenerator carriage. Before exiting its territory, the dining carriage, dormitory carriage and two hard sleeper carriages will be unloaded; after entering China, a dining carriage, a dormitory carriage and 2 hard sleeper carriages will be joined on.


1. As the Chinese and Mongolian rail widths are different, the trains change wheels while stopping at Erlian, which takes about 3 hours. During the process, passengers can stay onboard.
2. Apply for a Mongolian visa before boarding.
3.  K23 departing on Tuesday is operated by China, and the carriages are newly made in China. All the carriages are equipped with air-conditioners; the deluxe soft sleeper carriages even have their independent toilets and shower facilities. K23 departing on Monday is operated by Mongolia, but the carriages are made in China. All carriages have air-conditioners and two deluxe soft sleeper carriages share one toilet; shower facilities are not available.
4. In addition to K23, K3 also runs to Ulaanbaatar from Beijing, whose final stop is Moscow. K3 is operated by China and departs every Wednesday at the same time with the same duration of K23. There is no big difference between Chinese K23 and K3.

    It was all fine, thanks very much. Bit expensive compared to original cost, but I guess it's the only way to buy from abroad.

    Booking experience through TCG booking center is very good.

    Beijing Railway station is crazy busy and quite over whelming but once on the train - especially with a soft sleeper - everything is quite pleasant. The only thing is the bathrooms! Your operator was very kind and helpful. She was excellent and responded quickly to all emails. Her English is brilliant and she was exceptionally conscientious and put her best effort into contacting me. Thank you!

    Thank you for your service with booking these trains. Our booking experience through TCG booking center is fantastic. It doesn't appear to need any changes as service was exceptional. I booked on behalf of a colleague. She was impressed with the train journey though hence the train instead of flight

    Booked the first step of our trans Mongolian experience with Amber Liu. The communication has been very good. Tickets were at reception as Amber said they would be. (to our relief as we were traveling early the next day).

    Thank you for your service, because it all went as planned. I received my ticket at the hotel, and took the train on time, and the service and transaction was flawless.

    We found the train booking service provided by you absolutely flawless. It was perfectly handled and we got the tickets the moment we arrived in China and checked in at the first hotel.
    I was also impressed by the fact that the express service document was addressed in my wife's name, in whose name we had the hotel booking, though the bookings were handled by me and paid for in my name. That shows a very high level of diligence on part of your team. Thank you very much for the service provided.

    Booking was easy but I would have loved a PayPal option.

    My experience with booking of my tickets with Travel China Guide is very much satisfactory. Before my check in the tickets were ready at the reception counter of the hotel. Thanks for everything.
