- New Haven's FL9's were built with air whistles too. I can't remember the
- name of the company who made them (somebody Railway Supply Co.), but they look
- like the same type of whistle as on the MNS engines. I think Amtrak replaced
- the air whistles with standard "honkers" on their FL9's, but I don't know
- about Metro North. The record _First Generation Diesels, Volume II_ has
- two recordings of NH's FL9's, and the air whistle is certainly a lot nicer
- sounding than the one or two chime "moose calls" on other F's. Somehow, I doubt
- that NH had problems with meese anyway, but...
