In Assassin's Creed Syndicate, what is the name of the Frye twins' train headquarters?

In Assassin's Creed Syndicate, the Frye twins' mobile headquarters is called the Train Hideout.

The Train Hideout is a customized train that Jacob and Evie Frye use as their base while operating in Victorian London. It moves through the city and provides access to upgrades, equipment, and several supporting characters. Its mobility reflects the game's industrial setting and distinguishes Syndicate from earlier entries that generally use fixed safehouses.

The train is not the same thing as the game's carriage system. Jacob can drive motorized carriages around London for travel and missions, whereas the Train Hideout is the Assassins' strategic base. Players may also confuse it with named ships from other games, such as the Jackdaw and the Morrigan.

Syndicate takes place in 1868, during the Industrial Revolution. The twins build a gang called the Rooks and challenge Templar control over London districts. Although Jacob and Evie share the campaign, each has different abilities and mission styles, making the headquarters a shared base for two distinct playable characters.
