The so-called Carioca tram line is a Rio tourist attraction.  Its official name is the Santa Teresa tram.  It dates back to a horse-drawn tram line in the 19th century, and was electrified about 1896.  The Carioca name comes from an impressive former aqueduct viaduct that the line was built across after the aqueduct was abandoned.  Today the line no longer provides meaningful transport to local inhabitants, and is maintained primarily for tourist service.  The tram cars pictured here are the original unique home-built cars. In later years they became unsafe and have been replaced by modern replicas.  Although service was suspended for a few years for safety reasons, the line is back in service and still hauling tourists and a few locals (including friendly street urchins who will gladly steal your purse or wallet).
