Operations

The 03 series trains operated on the Tokyo Metro Hibiya Line, with through-running to and from the Tobu Skytree Line and before 2013, on the Tokyu Toyoko Line.

Formations

As of 1 April 2017, the fleet consists of 40 eight-car sets, formed as shown below, with car 1 at the Naka-Meguro (south) end.[3] Sets consist of four motored ("M") cars and four non-powered trailer ("T") cars.[3]

Car No.	8	7	6	5	4	3	2	1
Designation	CT1	M1	M2	Tc	Tc'	M1	M2	CT2
Numbering	03-100	03-200	03-300	03-400	03-500	03-600	03-700	03-800

• The M1 cars (cars 2 and 6) each have two lozenge-style pantographs.[3]
• Cars 1, 2, 7, and 8 in sets 09 to 28 have five pairs of doors per side instead of three.[3]

Withdrawal

The 03 series trains began to be replaced by new 13000 series trains from 25 March 2017.[4] The first set to be withdrawn, set 14, was removed for scrapping in February 2017.[5]

The 03 series was fully retired from the Hibiya Line on 28 February 2020 with no fanfare; Tokyo Metro cited the inconvenience created from the crowding of train enthusiasts during the farewell event for the 6000 series as the main reason for this decision.[6]

Resale

Kumamoto Electric Railway

Three former 03 series EMUs are scheduled to be resold for use by the Kumamoto Electric Railway in Kumamoto Prefecture between 2018 and 2020.[7] They entered service on 4 April 2019.

Nagano Electric Railway

On 31 January 2020, Nagano Electric Railway announced the second-hand purchase of a few 03 series units, which would be renumbered as the 3000 series. They're intended to replace the older 3500 series (ex-TRTA 3000 series, themselves too ex-Hibiya Line stock) wich currently form the backbone of local service rolling stock on the railway.[8]
