LEGO TRAM: The world's first full-size rail vehicle made entirely out of LEGO blocks was unveiled in Budapest, Hungary, on Wednesday (11/20). It took 7,000 hours to build the six-ton, nearly 38-foot-long tram car using 1.8 million LEGO blocks. The tram was made as part of a collaboration between LEGO Hungary and the capital's public transit company, BKV, and will be on display until December 20 to promote sustainable transportation.
