| 背面描述 | A detailed depiction of the high-speed Xueyu Shenhao train occupies the lower half of the field, rendered in high relief against a mirrored background, with a stylised mountain range in the upper field representing the Tibetan plateau. A schematic route map of the Qinghai–Tibet Railway traces the line through key stations labelled 'GOLMUD', 'TANGGULA - PASS', and 'LHASA'. The curved legend 'QINGHAI - TIBET RAILWAY' arcs across the upper portion, with 'XUEYU SHENHAO' inscribed above the date '2008' in the lower exergue, all within a beaded border. |

Laos issued this coin as a commemorative tied to the Qinghai–Tibet Railway, which had opened in July 2006 after decades of engineering debate over whether a standard-gauge line could survive the permafrost of the Tibetan Plateau above 4,000 meters. The project required the invention of new refrigeration techniques to stabilize embankments. Lao involvement is purely nominal — these pieces were produced for the international collector market under licensing arrangements common to small-state commemorative programs of the period.
