The number 28 Lisbon tram connects Martim Moniz with Campo Ourique, and passes through the popular tourist districts of Graca, Alfama, Baixa and Estrela. For visitors, this is the classic Lisbon tram journey, riding in the quaint yellow tram as it screeches and rattles through the narrow streets of the city. The delightful Remodelado trams date from the 1930s and in any other city they would be housed in a museum, but in Lisbon they are an integral part of the public transport network. These historic trams are still in use, as the 28 route is completely unsuitable for modern trams due to its numerous tight turns and steep gradients. A ride along the entire 28 tram route provides one of the best tours of the capital and is often a highlight of any holiday to Lisbon.
