I’m travelling Catania-Siricusa-Pozzallo-Pozzallo port later this month, so thanks for the heads up. Although OrarioTreni, the Italian train time app, doesn’t say anything about a bus replacement today on that line. However, it’s not overly concerning if it is a bus as from my previous experience, Italian Rail Replacement buses are fairly efficient and I’m assuming Siracusa is a staffed station so someone should be on hand to assist.
On the mainland, I noticed yesterday that preparation for further electrification on the Ionian Coast route in Calabria, between Sibari and Crotone is happening with masts being erected and some stations being re-designed.
