What is the name of the Assassin order's headquarters in Assassin's Creed Syndicate?

The Assassin order's headquarters in Assassin's Creed Syndicate is the Train Hideout.

The mobile headquarters is a train called the Rooks' carriage, which travels around Victorian London. Jacob and Evie Frye use it as a private base while building their gang, planning missions, changing equipment, and managing their campaign against Templar control of the city.

This headquarters fits the game's industrial setting. Instead of operating from a fixed villa or a conventional building, the Frye twins and their allies move through London by rail, reflecting the importance of steam technology and the expanding railway network during the Industrial Revolution.

The Great Inagua Hideout belongs to Assassin's Creed IV: Black Flag. Monteriggioni Villa is associated with Ezio's Italian adventures, while the Davenport Homestead is connected with Connor in Assassin's Creed III. These recurring headquarters can make the series' safe locations easy to confuse.
