Alexi 5000 (Earth-9471)

The Alexi 5000 was a train manufactured by Umbrella Auto and owned by the Weyland-Yutani Corporation. It was based on the secret research installation Hive, where it was used by employees to enter and exit the underground base.

History
During the xenomorph outbreak at the Hive, many personnel of the installation attempted to escape from it using the Alexi 5000, but the Red Queen, who was alerted of an outbreak, shut down all power within the facility, including the train, making any escape impossible. Two weeks later, the train was hacked, turned on, and used by the USCMC 2nd Battalion Bravo Team, Ellen Ripley, and Carter Burke, to regain access to the Hive and investigate the events that transpired on Aegis VII.

At the final hours of the Aegis VII Incident, Weyland-Yutani employee Carter Burke attempted to escape from the Hive using the Alexi 5000, but was caught off guard by a xenomorph Warrior and mauled alive. Ripley, alongside Rebecca "Newt" Ashford, Dwayne Hicks, Scott Gorman, and Jenette Vasquez escaped from the Hive onboard the train to rendezvous with Bishop and escape from the planet after a countdown they set to destroy the installation with the USS Sulaco's Shaw-Fujikawa Translight Engine. En route to the exitting the hive, however, and a xenomorph attacked the train, killing Gorman; in the ensuing confusion, Vasquez begged Ripley to kill her after sensing a Chestburster inside of her birthing, leaving Hicks, Ripley and Newt as the only survivors. The last xenomorph was finally killed when Hicks opened a hole on the train's floor, dragging the body of the alien along the tracks, then cutting it in half.

The Alexi, alongside all of the Hive, the Derelict, and the nearby New Alexandria, were destroyed once the slipspace drive exploded.
