Pinghsi Rural Township is home to 13 former mining sites. Chingtung, the terminus of the railway, was once a flourishing mining settlement. The long, narrow buildings are, unusually, built facing the tracks. Abandoned coal storage bins, coal-car tracks, and Japanese-style workers 'dormitories still stand intact.
平溪鄉全鄉有十三個礦場，其中鐵路終點菁桐坑原是個繁華的礦業聚落，長條型房舍是罕見地面對鐵路而建，廢棄堆煤場、運煤台車道、日式員工宿舍等礦業遺跡，至今保留完整。
