The traction motors were replaced with new PMSM (permanent magnet synchronous motors), as used on the Chiyoda Line 16000 series sets, and internally, 17 in LCD passenger information screens were added above the doorways. The same was done to fifth-batch sets 05-115 to 05-118 over the next few years, and eventually all sixth-batch sets 05-119 to 05-121 by the end of May 2020.
