The wide variety of whistles you hear on these engines is amazing, from Banshee whistles to Crosby 3 chimes, Nathan 6 chimes, a few 5's, and perhaps one of the most curious, a Norfolk and Western Hooter!
I admire your ability to differentiate the different whistles and what is more name them! With my non-musical ear I just enjoy the sounds of these magnificent machines. I started taking video so I could capture the sounds, something not possible with still images. Most Cuban steam locos are of US origin so it is perhaps not surprising you recognise the distinctive whistles.
Sad but true. The evil and vindictive US sanctions are trying to destroy the Cuban economy. Triste pero cierto. Las malvadas y vengativas sanciones estadounidenses están tratando de destruir la economía cubana.
