Let me continue where I left off my last year’s post.
The EMU 2000 series is the largest fleet on the Ina line of Saitama New Urban Transit Company (hereafter "the New Shuttle"). It was commissioned in 2007 to replace the decrepit 1010 series. 7 sets in total were built by Kawasaki Heavy Industries. Each set has a different body color. They are dark-pink (set 01), orange (set 02), green (set 03), yellow (set 04), blue (set 05), red (set 06) and pale-pink (set 07). Among these, the body color of set 01 was slightly changed from metallic-pink to dark-pink in 2018. It's a typical geek topic that trainspotters like to talk about.
Incidentally, the New Shuttle is a rubber-tired automated guideway transit (AGT). The 2000 series has a stainless-steel body. It was widened a lateral width compared to the previous models in order to alleviate congestion during the rush hour. The one set is composed of six motorcars. The power supply is 600V three-phase alternate current. Instead of an overhead catenary, three rigid wires are installed along the track. The electric control system on the 2000 series is IGBT-VVVF (Insulated Gate Bipolar Transistor - variable frequency drive) inverter. It means that the three-phase alternate current is once converted to direct current by converters, and converted again to three-phase alternate current by inverters on the train to control traction motors. Each set has six 125 kW traction motors. The maximum operating speed is 60 kilometers per hour.
