Horn for C&O/Chessie GP9

[_o_OOOO_oo-Kanawha]

Looking for the right horn sound to go with the COARW fleet of C&O and Chessie System GP9's.

Searching the net gave me very few hits, but for this Leslie S5T horn apparently taken from a C&O GP9:

Question: is it available in Railworks?

The RSC model has two two chime horns mounted on the roof. What types are these supposed to be?

The horns would be a Leslie S5T/RS5T. Later in life, they might be a Leslie RS3L. Only a few had those, so a S5T would be a safe bet!
