Greetings - Can anyone identify the horn-type on this NYC SW7? I picked up a Paragon 2 BLI SW7 recently and it has three horn choices. The 1st and 3rd are monotonal and the middle one is tritonal. My guess is that the tritonal horn would have been used with an EMD E- or F-unit??? I'd like to choose the proper one for an NYC SW7. Thanks for the help.
Looks like a WABCO A-2. This was used on most NYC switchers. Pictures and sound samples are here: http://atsf.railfan.net/airhorns/a2.html Mike
