What is the name of the main setting in Resident Evil 0’s opening chapter?

Resident Evil 0’s opening chapter is set aboard the Ecliptic Express.

The train is the first major location explored by Rebecca Chambers and Billy Coen. It has passenger cars, service areas, a dining car, and other compartments that become interconnected puzzle spaces as the outbreak spreads through the train. The opening establishes both protagonists and the game’s unusual partner-based structure.

Resident Evil 0 differs from earlier entries because items can be dropped onto the floor instead of being stored in traditional item boxes. That system is introduced during the train section, where limited inventory capacity makes route planning especially important.

The Ecliptic Express is not the same as the Umbrella Training Facility, although both locations are connected in the story. After the train sequence, the characters reach Umbrella’s training complex, where the investigation into the outbreak and the company’s experiments continues.
