China Railway Train Numbering Rules
The compilation of trains is related to uplink and downlink. The direction of railway entering Beijing or from branch line to trunk line is called ascending, and the direction of leaving Beijing or from trunk line to branch line is called descending. The number of trains going up is even (even) and the number of trains going down is odd (odd). For example, T 1 1 is odd, because it is from Beijing to Shenyang.
The turn-back train T 12 is from Shenyang north to Beijing, which is upward, so it is even (even). In addition, other cars will also change the number of trains because of the change of uplink and downlink routes, such as K388/385 386/387, between Shenyang North and Chengdu, and from Shenyang North to Beijing, so the number of trains is K388.
After the train stopped in Tianjin, it began to leave Beijing and changed to the downward direction, so the number of trains was changed to K385 at the same time. The same is true of driving from Chengdu to Shenyang North. Before arriving in Tianjin, the train number was K386. After stopping in Tianjin, the train number is K387. For example, the train from Shenyang North to Tianjin goes up K388 and down K387.
