Design

Based on the earlier Tokyu 9000 series design, the 1000 series trains were built for use on through-running services to and from the Tokyo Metro Hibiya Line subway.[1] Cars are 18 metres long and have three pairs of doors per side.[1]

Operations

Three-car sets have operated on the Tokyu Ikegami Line since 1993.[1] Four-car sets formerly operated on the Tokyu Mekama Line (present-day Tokyu Tamagawa Line and Tokyu Meguro Line), and eight-car formations formerly operated on the Tokyu Toyoko Line, with through-running to and from the Tokyo Metro Hibiya Line subway. The former were reformed as three-car sets, and the latter were taken out of use from 15 March 2013.[1] From May 2014, former eight-car Tokyu Toyoko Line sets were reformed into three-car sets and refurbished for use on the Tokyu Tamagawa Line and Tokyu Meguro Line, reclassified as 1000-1500 series.[2]

Formations

3-car sets

As of 1 April 2013, the fleet consists of nine three-car sets, formed as follows, with two motored ("M") cars and one non-powered trailer ("T") car, and car 1 at the Gotanda/Tamagawa end.[3]

Car No.	1	2	3
Designation	Tc	M	Mc
Numbering	1000	1200	1300

Sets 1012 and 1014 have end cars with a central gangway door instead of the offset emergency gangway door on other units.[3] These two sets were originally built as four-car sets designed to operate in pairs on Toyoko Line through services.[4] Cars 2 and 3 are each fitted with a single-arm pantograph.[3]

• The 150x cars were converted from former 100x driving trailer cars, the 160x cars were converted from former 120x motor cars, and the 170x cars were converted from former 110x driving trailer cars.[2]
• The 160x cars are fitted with two single-arm pantographs.[2]
• The motor cars are mounted on TS-1006 bogies, and the trailer cars are mounted on TS-1007 bogies.[2]

8-car sets

The eight-car sets used on the Toyoko Line up until March 2013 were formed as follows, with car 1 at the northern end.[3]

Car No.	1	2	3	4	5	6	7	8
Designation	Tc2	M2	M1	M2	M1	M2	M1	Tc1
Numbering	1000	1250	1200	1350	1300	1450	1400	1100

Cars 3, 5, and 7 were each fitted with a lozenge-type pantograph.[3] Cars 2 and 7 included wheelchair spaces.[3]

Interior

Passenger accommodation consists of longitudinal seating throughout, with a mixture of brown and orange seat moquette.[1] The 1000-1500 series sets formed from 2014 have light green seat moquette and a wheelchair space added in the 160x cars.[2]

History

Initially introduced on the Tokyu Toyoko Line from 26 December 1988,[5] they were also introduced on the Mekama Line from 1991. These were transferred to the Ikegami Line from 1992, and further new trains were built for the Ikegami Line in 1993.[1] The last set delivered, 1024, was the first Tokyu EMU to be built with a wheelchair space.[1] The Ikegami Line fleet underwent modifications in 1998 for use on wanman driver only operation services.[1]

Livery variations

From March 2016, three-car set 1017 received a dark blue and yellow retro-style livery based on the livery applied to the 3450 series trains that operated on the Ikegami Line until 1989.[6]

Withdrawal and resale

Withdrawals started in 2008, with some cars being resold to the Ueda Electric Railway and the Iga Railway.[1] Further cars were resold to the Ichibata Electric Railway in 2014,[4] and to Fukushima Transportation in 2017.[7]

• Ueda Electric Railway 1000 series and 6000 series
• Iga Railway 200 series
• Ichibata Electric Railway 1000 series two-car sets (since February 2015)
• Fukushima Transportation 1000 series two- and three-car sets (since 2017)

Ueda Electric Railway

Eight former Tokyu Ikegami Line 1000 series end cars were resold to the Ueda Electric Railway in Nagano Prefecture, and reformed as four two-car 1000 series sets.[8]

In 2015, two former Tokyu Toyoko Line 1000 series intermediate cars (DeHa 1255 and DeHa 1305) were resold to the Ueda Electric Railway, which were reformed as a two-car 6000 series set with the addition of new cab ends.[4]

Iga Railway

The Iga Railway in Mie Prefecture operates five two-car 200 series EMUs formed from ten former Tokyu 1000 series cars (from former sets 1010, 1011, and 1006) purchased between 2009 and 2012.[8]

The two end cars from the former eight-car set reformed from two four-car sets 1010 and 1011 were resold to the Iga Railway in 2009 after the set was withdrawn. The six intermediate cars of the set were scrapped.[4] The two intermediate driving cars (with central gangway doors) originally formed in sets 1010 and 1011 before they were combined to become a single eight-car set were also sold to Iga Railway in 2010.[4] Following its withdrawal in June 2009, eight-car set 1006 donated six cars, which were resold to Iga Railway between 2010 and 2012. The other two cars of the set were scrapped.[4]
