The New 101 series features changes in design.[4] The 301 series is based on the New 101 series,[5] and were formed as eight-car sets.[2]
The Chichibu Railway 6000 series trains were rebuilt from former Seibu New 101 series trains.[6] Sangi Railway operates former New 101 series trains as Sangi Railway 751 series.[7] Former Seibu New 101 series trains were also transferred to Ryutetsu, becoming Ryutetsu 5000 series trains.[8]
In 2018, one set received a livery resembling the Ohmi Railway 100 series.[9] Other livery variations include a set in Izuhakone Railway livery,[10] and a set in red and beige livery.[11]
