	An Auran USA '''Absolute''' signal maintains absolute control on the driver.

	Being dedicated to realism, Trainz is designed to simulate real railroads, and all real railroads have drivers which are not infallible. And so in Trainz, the drivers will occasionally "pass a signal at danger", meaning they do through red absolute ~~signals~~. Their train is abruptly thrown into "Emergency" (i.e. the air pressure line running through the train's entirety is vented, causing all individual carriages/cars/wagon air systems to engage their braking). There is nothing the user can do about this, except design a route to mitigate this fallacy. An emergency train will remain where it comes to rest for two minutes, sufficient time to recharge trainwide air pressure.
