While I was looking through my posts here recently, I realized that some of the train travel illustrations may be outdated, but that most of the commentary still applied. Websites may look different, but you can still navigate them easily to set your itinerary, reserve lodging and buy some train tickets.
Hopefully, in the near future, we will be up for another trip to the country we love the most to visit - Italy! There is so much we have yet to see. Both of us can still imagine traveling to the towns where our grandparents and/or our great grandparents emigrated from in the early 1900s. Mine came to the US from Pedavena (https://www.tripadvisor.com/Tourism-g776154-Pedavena_Province_of_Belluno_Veneto-Vacations.html) in northern Italy in 1904. My wife's traveled from Atena Lucana ( https://en.wikipedia.org/wiki/Atena_Lucana ). So, you see, we still travel imagining.
There is a lot of interesting and useful information for you here. Remember, "Italy Is Waiting For You - Get Going!"
