I’m planning to travel to Sicily in june and want to take the night train back from Siracusa to Milan on june 24. However, when looking for availability on raileurope or italiarail, thay can't sell me a reservation for this train on that day. When going to the Trenitalia website, it shows that the train is running, bus not being bookable. Does anyone know why this might be the case? Engineering works?

On the dates before and after june 24 the train is bookable, but only couchettes, sleepers are not available. This is the case for the whole of june and a large part of may. It seems that may 14 is the last day for which a sleeper compartment can be bought. Are these completely axed from the Milan - Sicily route during the summer?
