Answer: - - O - (long, long, short, long)
Feedback:
This whistle must be prolonged or repeated as necessary until the engine completely occupies the crossing(s). Not all public crossings have gates or lights. Sounding the whistle is an additional procedure to help ensure the safety of the crews and the public.
