 | | Its only highâ“speed rail service at present is in the Northeast Corridor between Boston â“ New York â“ Washington, D.C. ; it uses tilting trains to achieve high speeds (though lower than those of their European and Japanese counterparts) on previouslyâ“existing tracks, since building new, straighter lines was not practical given the level of funding. |
 | | By building a new rail infrastructure with 20th century engineering, including elimination of constrictions such as roadway atâ“grade crossings, frequent stops, a succession of curves and reverse curves, and not sharing the rightâ“ofâ“way with freight or slower passenger trains, higher speeds (250â“300 km/h; 155â“185 mi/h) are maintained. |
 | | The recognition of the interâ“relationship between land development and the highâ“speed rail network led, in 1970, to the enaction in Japan of a law for the construction of a nationwide Shinkansen railway network. |
