Why was chengdu-kunming railway abandoned?

Some sections of chengdu-kunming railway were flooded by wudongde hydropower station, and a new line has been repaired to bypass the flooded sections.

Chengdu-Kunming line is still in use! Only part of the road sections were flooded by wudongde hydropower station after impoundment and needed to be demolished. The new line has been repaired, bypassing the flooded section. Secondly, the travel problem of fellow villagers along chengdu-kunming railway. No.7466/5 ordinary speed train stops at various stations along the Yunnan section of chengdu-kunming railway, commonly known as green leather car, slow train, station music and small ticket car. All the villagers in the flood-stricken area have moved away.
