The obligatory link: French train smashes world speed record
I'll state from the start, they're talking about the speed record for trains on rails. Thus, the speed records for the magnetic-propulsion train tests in Japan don't count. Still, the train in question came within about four miles per hour of that record. (357mph versus the maglev record of just under 361mph in 2003.) For comparison, from Wiki, the world land speed record is currently 763mph for four-wheeled vehicles (the unlimited classification) and 351mph for motorcycles.
