Railway Terror tells the story of an eight-person team called the Trackwalkers, struggling to survive as they travel through the eerie space known as the Rail Domain. Whenever they board the last train at a designated subway station, they are swept into this dangerous alternate dimension. To survive, they must find the one and only Safe Platform before the train reaches its final stop.
The team is led by its two male protagonists, Cen Yan and Pei Chen. Cen Yan can sense dangers along the tracks and map out escape routes, while Pei Chen wields the Railblade, which can cut down ghosts and monsters, and boasts extraordinary defensive power. Xu Shutong, a female train attendant, knows the platform rules and can accurately identify safety signs and deadly traps. Shen Zhiwei, a female mechanic, excels at dismantling and repairing track equipment; on multiple occasions, she has repaired signal lights to give the team a chance to survive. The four male teammates each have their own role: assault specialist Shen Hengchuan is astonishingly quick to act and uses a specially made crowbar to break through blockades; shield guard Wen Jingcheng uses an alloy shield to form a temporary defensive perimeter; medic Xie Qinghe carries an upgraded first-aid kit to treat the unusual wounds inflicted by ghosts and monsters; and scout Gu Xingci keeps watch in every direction, spotting disturbances in the shadows early and providing Cen Yan with vital information for planning their route.
The team works together seamlessly, ready to stay behind for one another in a crisis. When Cen Yan marks out a route, Pei Chen guards the most dangerous direction without a word. When Pei Chen is surrounded by rail ghosts, Cen Yan can always point out a gap just wide enough for one person to slip through. To outsiders, they say only, “Stick with us.” With each other, they share their weaknesses and dangers without holding anything back. In the face of desperation, they entrust their lives to one another, relying on trust and their individual strengths to fight for a chance to survive in the Rail Domain.
