How do you recover after a coaster crash in Roller Coaster Tycoon?

Solution 1:

Try switch to the red flag and click the red flag again, It worked for me in R.C.T.2 but I am sure it should work in the first version too.

Solution 2:

An easy way to avoid a crash is to place brakes before the station platform. Also, it's best to have a mechanic that fixes only that ride. If your roller coaster crashes, double-click the stop light to reset it. This will reopen it, but more than likely no one will want to go on it because "It isn't safe." Best thing to do is to save frequently andd just load a file after it crashes.
