RIO DE JANEIRO (Reuters) - Workers in hard hats and coveralls were still working on Rio de Janeiro's newest subway line on Monday, two days after it was inaugurated by Brazilian leaders and four days before the start of the 2016 Olympics it was built to serve.
The 10-billion-real (2.35 billion pounds) Line 4, designed to be the main mover of people to and from the Olympic Park in Rio's distant Barra beachfront neighbourhood, was scheduled to be the biggest legacy project of an Olympics where many other urban improvement promises, such as cleaning up sewage or reducing air pollution, have not been met.
