 Plans also exist for the construction of short portage railways bypassing the dam area altogether . Two short rail lines , one on each side of the river , are to be constructed . The 88 kilometer long northern portage railway ( 北岸翻坝铁路 ) will run from the Taipingxi port facility ( 太平溪港 ) on the northern side of the Yangtze , just upstream from the dam , via Yichang East Railway Station to the Baiyang Tianjiahe port facility in Baiyang Town ( 白洋镇 ) , below Yichang . The 95 kilometer long southern portage railway ( 南岸翻坝铁路 ) will run from Maoping ( upstream of the dam ) via Yichang South Railway Station to Zhicheng ( on the Jiaozuo – Liuzhou Railway ) .
