(Capcom's primary storyline)
"This is Delta Team. This is Delta Team. We have gained control of the train. Over."
Delta Team was a unit within the Umbrella Security Service team. It was sent to the Ecliptic Express to investigate the t-virus outbreak that had occurred. Gaining control of the train, they reported back to Albert Wesker and William Birkin, who had by then decided to destroy the train completely in an attempt to keep the leak under wraps. However, while they were still ten minutes away from the nearest branch line, they were swarmed and killed by leeches. They later turned into zombies.
