The rail car is a whale oil-powered vehicle, which is one of several types of transport used in Dunwall. As with most land-faring vehicles in the Isles, cars run on rails. Based on their appearance and utilization in Dishonored, rail cars are likely reserved for the most affluent and elite of Dunwall and the City Watch.
The standard rail car is a four-wheeled affair, each wheel of which is on a separate dedicated rail. The front two wheels each have a forward-mounted pilot, to catch and expel small objects and even rats out of the vehicle's way. Located above the front right wheel is a large forward-facing lamp to illuminate the way, as well as another smaller lamp located just above the left window.
Heavy metal doors are positioned on either side, some versions of which open outward, while others slide backwards exposing the interior. The interiors of most rail cars boast cushioned seats that face each other. Overheard illumination in the interior of the cab is provided by a fluorescent tube light bulb on the ceiling as well as small viewing ports. There are speakers set in the vehicle walls next to the seats for the passengers' entertainment.
On the roof of the vehicle is a large trunk for the travelers' use, held in place by sturdy straps. The rear of the vehicle also seems to have a heraldic symbol of some kind painted on the back plate, most often a winged bird behind a diamond shape.
- Rail cars bear a resemblance to the Combine APC in the Half-Life series, and the Art Director of Dishonored, Viktor Antonov, was also the Art Director for the Half-Life series.
- Rail cars are most likely automated vehicles, as the view ports are extremely small and limited, and there is no apparent driving apparatus.
- The only moving rail car in Dishonored is in the main menu, driving through a wall of light on John Clavering Boulevard.
- Rail cars can be seen in the main menu where one rolls onto John Clavering Boulevard, the remains of one in the sewers outside Coldridge Prison, outside the Golden Cat, outside the Boyle Mansion, in the Flooded District near Daud's Hideout, next to the Timsh Estate, and some on the docks of the Drapers Ward Riverfront including on the cargo ship the Undine.
