Thanks so much for posting this interesting map. Do you know the times when your great-grandfather was in 160 Railway Construction Company? My father was in that unit from end of 1944 until 1946. I am awaiting the war diary for 160 Railway Construction Company, when I receive it I will post it here. Tim
There are some photographs of 160 Railway Construction Company at the Imperial War Museum. Just go to their website and do a search with the words: eighth army italy railway reconstruction.
