If Bermuda was car free then I'd be less terrified by the taxi rides to and from the airport every year. *Thinks about it* It would be a bugger to cycle there with my suitcase though.
Looking at their rolling stock, I would consider it a gasoline and diesel-powered Interurban or Light-Railway for our UK friends. Not a single locomotive on their roster, just box motors that could pull a few cars.
Looking through the Bermuda railway pages, there is no mention of signalling and given their use of bus-sized railcars, this makes me wonder if they were just driven on sight. One question that remains is why the bend in the railway near Hamilton?
Why not a straighter section of line there and a branch to Hamilton?
