Yam was a postal system or supply point route messenger system extensively used and expanded by Ögedei Khan and also used by subsequent Great Khans and Khans. Wikipedia

A stage station or relay station, also known as a staging post, a posting station, or a stage stop, is a facility along a main road or trade route where a traveller can rest and/or replace exhausted working animals for fresh ones, since long journeys are much faster with less delays when using well fed and rested mounts.
