While working on our next trip to Italy I came across this announcement from the Italo Train system. some new routes will start in May, others this summer.

"From 1 May 2018 a host of new stops
With Italo you can stop at Brescia, Desenzano, Peschiera del Garda, Verona, Vicenza, Padova e Venezia Mestre leaving both from Milano Centrale and Venezia (Venice) S.Lucia.
More connections, faster journeys
Up to 14 connections per day on the Milan-Venice route will be introduced by 1 July 2018 allowing you to reach the centre of each city in just 2 hours and 25 minutes."
