Beijing Subway Line 8 has introduced the "Central Axis Train", incorporating the architectural elements of 15 cultural heritage sites along the central axis into its design. The doors of each carriage display cultural pictures of the central axis, while the seats are adorned with silhouette stickers of central axis buildings. The handrails and rings feature hand-painted landscapes of the central axis.

Furthermore, the "Time Train" of Beijing Subway will be relaunched, this time under the theme of "Ride the Time Train for a Joyful Summer Journey". New information guiding the routes to parks, museums, and other attractions along Line 1 Batong Line has been added to the carriages.
