4 vehicles in Assassin's Creed Syndicate.
Boats
Steam riverboats travel up and down the Thames in Syndicate. You cannot steer them; instead they work as moving platforms you run and jump across to cross the river without swimming.
Carriages
Horse-drawn carriages are the fastest way across Syndicate's London, and the twins hijack them whenever they need one. The twins drive them in chases, races, escort jobs and fights on the move, and Rooks carriages join the traffic once you buy the right gang upgrades.
Train Hideout
The Train Hideout is the Frye twins' moving headquarters in Syndicate, a steam train its driver Agnes MacBean calls Bertha. You win it from the Blighters in the Whitechapel gang war, and it keeps running between London's stations while you plan, craft, shop and collect the Rooks' income.
Trains
Steam trains run between Syndicate's London stations, and you use them to get around the city, fight on their roofs and rob them. Railways appear for the first time in the series in this game, and the Rooks hold up money trains to fund the fight against the Templars.
