Trains are locomotives and coaches designed to move on rails, used for transporting cargo or passengers.
During the 19th century, London trains provided routes for Edinburgh, Liverpool, Oxford, Cambridge, Brighton and Dover. Open-topped carriages were available for the poor. In 1834, English and Scottish rail lines merged, allowing people to travel faster between the two places. Queen Victoria was the very first monarch to ride a train in 1842.
The first rail factory was owned by the Starrick family and inherited by their youngest son Crawford, who used it to expand his Templar influence and business throughout London. Sometime in mid-19th century, Starrick impounded a Herwicke Steam Engine which was owned by Agnes MacBean and nicknamed "Bertha". He then placed the train and MacBean under his Templar accomplice Rexford Kaylock. Kaylock, as the Whitechapel Blighters gang leader, equipped the train for their operations.
In 1860, several large railway companies donated money for the first underground railway transport under the plans of Charles Pearson. John Fowler was also hired as the chief engineer. However, the construction caused many families to lose homes and roads to be blocked. It also used the technique "cut and cover" which involved sinking of trenches and reinstating the surface.
The American transgender, Ned Wynert, and his group of thieves used London's transit systems as cover for their criminal activities. Ned was able to rob many shipments coming into the city of their valuables.
By 1868, the Assassin siblings Jacob and Evie Frye destroyed the Whitechapel Blighters with their new syndicate, the Rooks. With MacBean's permission, the twins made the locomotive their mobile hideout. Together with the Assassin Henry Green, "Bertha" was used to plan and track all known active London Templars by the Fryes, who also took a carriage for themselves as a place for them to live while in the city. Much later, they gained the aid of Nigel Bumble, who worked under MacBean in fixing and repairing the train.
With Ned Wynert's assistance, the Rooks would also rob trains carrying money to fund their operations. Jacob Frye also had to visit trains and stations to assassinate Templars and destroy Blighters shipments.
- In Assassin's Creed: Syndicate, there is a red tender engine seen hauling passenger trains around London named "The Great Eagle" with the number 1191, referencing the sobriquet of Altaïr Ibn-La'Ahad and the year Assassin's Creed took place, respectively. Additionally, there is a black tank engine with the number 1476 on the front of its smokebox, referencing the year Ezio Auditore da Firenze began his quest to avenge the deaths of his father and brothers. The train locomotive itself is based on the G.W.R. type engine, City of Truro.
- The S.E.R black tank engine is based on a LB&SCR A1x Terrier class tank engine, though painted in British Railways' lined black livery, complete with smokebox number plate, and lettered for the South Eastern Railway.
- Both types of engine designs present in Syndicate are historically inaccurate. The A1x class tank engines in their original form, as the A1 class, were only introduced in the 1870s, while the Duke class started being built in the 1890s. Additionally, the black livery of the A1x was not used until the late 1940s. The G.W.R class City of Truro was not built until 1903.
- It is also uncommon to catch trains at stations and cannot go reverse out of stations such as St. Pancras Station, Victoria Station, and Charing Cross Station.
