Dcc sound for a caboose

[Rscott417]

I'm looking to model a (ho scale) CSX transfer caboose. The prototype actually has a horn/whistle on it for grade crossings during switching moves. The caboose has an awful high pitched squeaky whistle that I think would be a great addition for a model. Does anyone make a sound decoder for a caboose? Here's a video of the caboose I'm looking to make.
