As soon as your coaster leaves the lift, hit F12. Once it is at a complete stop in the MCBS (Mid Course Brake Section), hit F12 to disable it. If it makes it back to the end brake without crashing into the coaster in the station, the E-Stop has passed. If you're thinking "how do I keep the 2nd coaster in the station," hit F11 as soon as the coaster you're in is on the lift to enable manual mode, but do not launch next coaster. If you have more than 2 trains you will have to make sure it doesn't fly through the brakes and into the other coasters. Hope this helps! [:)]
