“Little Americas: is what the trolleys were called when they first arrived in Lisbon. Why “little americas”? The trolleys were bought from New York. Lisbon has a lot of lines with many Trolleys on the road and a modern light rail system as well.
The Trolleys navigate the hills well and provide transportation for both tourist and local people. In Porto there are trolleys and a Trolley museum. The museum was housed in the early electricity generation plant built when the electric service was started in 1895.
