Vossloh G2000 locomotives equipped with ATB EG suffer from some unwanted emergency brake applications. This is because the brake pipe pressure, on which the brake criterion is based, takes 4 to 5 seconds to drop, while the ATB intervenes in 3 seconds.FLIRT trains have the same problem as the G2000 locomotives, because their brake criterion is based on the brake cylinder pressure. Additionally the brake criterion can "vanish" when the anti-lock braking system engages, because the system could reduce the brake pressure below the point to comply with the brake criterion. This will also result in an emergency brake application.
