Tobu 80000 series

The Tobu 80000 series (東武80000系) is a commuter electric multiple unit (EMU) train type on order by the private railway operator Tobu Railway in Japan. Twenty-five 5-car sets are to be built.

Overview
Details of the 80000 series trains on order were first announced in April 2024. In light of declining ridership on the Tobu Urban Park Line following the COVID-19 pandemic, Tobu Railway decided to reduce train capacity (from 6-car sets to 5-car sets) instead of reducing frequency.

The 80000 series is slated to replace ageing 8000 and 10000 series EMUs, which were relegated from services on busier lines. The 25 sets will be built by Kinki Sharyo. Seven sets will be entirely new-build, and the remainder will be built as 4-car sets, each receiving a modified 60000 series intermediate car to form a 5-car set.

The trains will use a traction system incorporating synchronous reluctance motors, a first for major private railways in Japan.

Design
The 80000 series will use the same body construction as that of the 60000 series, although the type will incorporate a curved front-end design. Cars will carry a "future blue" and "bright green" livery.
