what would it sound like if UP 3985 had N&W 1218's hooter whistle?

what do yall think 8)
It would sound like a hooter whistle. Whistle sound is affected by PSI. A whistle can sound slightly different when operated at a different PSI. Check out some videos on Youtube if you are really interested.
As for an N&W hooter on Western steam like the UP 3985...it's blasphemy.
