A while ago there was an ongoing thread about building a scale model of a Great Lakes ferry. I'm not sure where that thread was; so I'm posting this here.
I thought of that last night after watching this video that a friend sent to me.
The Solano was a large railroad ferry, built as a reinforced paddle steamer with independently powered sidewheels by the Central Pacific Railroad, that carried entire trains across the Carquinez Strait between Benicia and Port Costa in California, daily for 51 years from 1879 to 1930. When launched, the Solano was the largest ferry of its kind in the world, a record held for 35 years until 1914 when she was joined by her sister ship, the Contra Costa, which was 13 feet longer.
