The 207 series (207系) or 207–900 series (207系900番台) was a commuter electric multiple unit (EMU) train type introduced in 1986 by Japanese National Railways (JNR) and operated by East Japan Railway Company (JR East) on through services between the Joban Line and Tokyo Metro Chiyoda Line.^[2] Only one 10-car set was built, which was withdrawn in December 2009.

Design

Based on the earlier 205 series design, the 207-900 series was a prototype built as the first VVVF-controlled EMU operated by JNR.^[2] The 207 series built later by JR West bears no relation to this train.^[3]

The train used adjustable voltage/adjustable frequency (AVAF) inverters and induction motors using gate turn-off thyristor (GTO) components.^[4]

Formation

The sole 10-car set, numbered "71", was formed as follows, with car 1 at the Yoyogi-Uehara end and car 10 at the Toride end.^[1]

Car No.	1	2	3	4	5	6	7	8	9	10
Designation	T'c	M2	M1	T2	M2	M1	T1	M2	M1	Tc
Numbering	KuHa 206-901	MoHa 206-903	MoHa 207-903	SaHa 207–902	MoHa 206–902	MoHa 207–902	Saha 207–901	MoHa 206–901	MoHa 207–901	KuHa 207–901

Cars 3, 6, and 9 were each fitted with one PS21 lozenge-type pantograph.^[1]

History

The train was delivered to Matsudo Depot in November 1986.^[3]

It was withdrawn from service in 2009 following the introduction of new E233-2000 series EMUs, and a final "Sayonara" service was run on 5 December 2009.^[5] The train was transferred to Nagano on 5 January 2010 for scrapping.^[6]
