Thanks for filling in the details. Nice post.
I was thinking of historic floods like the 1951 Polesine flood which destroyed so much infrastructure but, yes, the main line ran North of this event.
There were OTL large sugar cane plantings in Cyprus at least under Venetian rule. Also on Crete. Unfortunately slave labor was employed.

Thanks: I always say that the devil is in the details.
Polesine is low lands. and historically has been easily floodable. You may be interested in this link, which tells the story of the reclamation of Polesine http://www.itempidellaterra.org/4/8.php Did your family originated from there?
I was pretty sure I remembered the cane sugar plantations of Cyprus and Crete (which were marginalized later on by the sugar cane plantations of the Caribbeans). The use of slave labor is unfortunate for sure. I'm afraid however that each age dictates the economics of production: marginal plantations require slave labor or indentured labor (the same happened in Queensland under the illuminate government of Queen Victoria, with indentured labor brought in from Pacific islanders. After WW2 a significant number of Italian immigrants worked the same plantations, and ended up buying them from previous owners, but that is another story).
Thanks for the link.
