Ha ha! Look at you! You look like you ran through traffic!

A Train is an environmental hazard which first appeared in the map Well, and has been used in other maps since. Trains typically appear on the map in the form of a railway crossing complete with warning lights and a ringing bell sound effect. The speed and the timing of the Train's appearance varies by map. Sometimes the train will be only an engine, and other times it will be pulling flatcars or boxcars. Originally, the hazard was represented by a common 1970s locomotive model (similar to a EMD GP38-2), but was later also represented by Li'l Chew Chew (on Frontier), Metro coaches (on District), and a historic Badlands diesel switcher locomotive (on Banana Bay).
Contact with the front of a Train results in the destruction of buildings and death of the player, including players currently receiving an ÜberCharge from a Medic. Players who cause an opponent to be struck and killed by a train through knock back or wound the player by any other means before the death will not be credited with a kill assist.
- Stickybombs launched at a moving Train will be stuck in the air at the point where the Stickybomb and Train met, instead of moving along with the Train.
- This bug does not occur for the Train in Snowplow — stickybombs bounce off whether it is moving or not.
- The trains' air horns appear to be Nathan K3LAs.
- The Train on most maps bears the imaginary company name "Northern Express" while it resembles the historic real-life U.S. railroad, Southern Pacific.
- The Northern Express Train has a paint scheme that matches the "Bloody Nose" standard that Southern Pacific used from 1958 to 1991, with the exception that the characteristic SP nose wings are not the standard Sunset Red but instead are the rare "Halloween" orange that SP experimented with around 1958.
- The GP38-2 was operated in Southern Pacific's fleet as well -- that railroad operated south and east of the Badlands.
- The Northern Express Train's number of '7331' is the popular gaming phrase 1337 ('leet' in numbers, a text version of the word 'elite') backwards.
