Machinist Sergio San Martin turns a part for a carriage wheel on a lathe in a workshop in Montevideo in this picture taken March 26, 2008. Montevideo's city hall is building replicas of old carriages that are going to be used by tourists to visit the city. The carriages will be driven by former garbage pickers who have been encouraged to leave their informal jobs as recyclers, and have been taught public relations, English and the city's history.
