I am on it now. See if I can supply you with a film of any TCDD steamer blowing its whistle.
They were all very special, very high pitch and all the drivers had a way of blowing them. i.e, blowing their own tunes,playing with it, like a symphony. Everyone new it was that driver pulling in the station just by hearing the sound of his whistle.
This liliput has that pitch.
The whistle types in loksound are all Germanic in nature.The closest is the sound of the Br78 and Br55.
