The Railway Technical Research Institute in Japan announced in April, 2015 that they succeeded in transporting a current of 2000A for a real train operation in a Tokyo suburb area (photo on the left shows the HTS cable). This system was tested in 2014 in their laboratory railway center, which has a train running with 310m long transmission cable. They expect more efficient power use in a train system such as reduction of power loss or substation using HTS DC train cable.
