This may suggest that the trains are automated however, all locomotives have what appear to be a driver's cab and a ladder leading up to it. This can range from vehicles, Citizens, Rebels and even friendly Combine units. Razor trains are very fast-moving and completely unyielding to any object that may be on the tracks they will simply ram their way through any obstacle blocking their path. The sound of the horn varies, however, as several times during Half-Life 2 and its Episodes, they emit lower or higher air horn blasts instead. They also transport Stalkers and Overwatch Soldiers to the Citadel.Īnother disconcerting aspect of the Razor Train is its horn: a distinctive bellow that announces the Train's arrival. Notably, Razor Trains are used to transport human prisoners to Nova Prospekt, the Combine-controlled prison/laboratory. Razor Trains have been designed and built to work on human rail networks and are used for transporting cargo, human prisoners, Stalkers, and Combine Advisors. As with much of Combine technology and architecture, the Razor Train is large, mostly featureless, and imposing. Like the Hunter-Chopper and Combine APC, the Razor Train is an adaptation of human technology, redesigned with Combine technology and aesthetics.
