Build a rail network to deliver the souls of the damned to their infernal destinations. That is the odd theme of the HellRail games. Beginning with HellRail: Second Perdition, some unique game mechanisms were introduced. Each card may serve one of several functions: track, cars of passengers, movement allowance, and a way to purchase additional cards. With the advanced rules, special abilities are awarded when arriving at specific stations (circles). The unusual theme was stripped away but the core gameplay was kept for FrachtExpress. FrachtExpress also added crossing tracks.
