Design
editBuilt jointly by Kawasaki Heavy Industries and Tokyu Car,[2] the design is derived from the 209 series commuter EMU, and were initially operated as 10 5-car formations on Jōban Line services out of Ueno in Tokyo, but were modified with the addition of toilets and transferred to Jōban Line and Mito Line local services in the Mito area from March 2007.[3]
Formations

editAs of 1 October 2018, four ten-car sets (K701–K704) are based at Katsuta Depot and formed with four motored ("M") cars and six non-powered trailer ("T") cars.[4]

History
editThe first 10 5-car train was originally scheduled to be delivered in time for entry into service from the March 1995 timetable revision, but deliveries from Kawasaki Heavy Industries in Kobe were delayed until May due to the effects of the Great Hanshin earthquake in January of that year.[3] The first trains ultimately entered revenue service from the start of the 1 December 1995 timetable revision.[5][4]
Between September and October 2006, modifications were made to the side windows to allow some windows to be opened.[5] From October 2006, the fleet underwent modifications to add toilets, and from the start of the 18 March 2007 timetable revision, the E501 series trains were displaced from Jōban Line services out of Ueno by E531 series sets, and were transferred to local services on the Jōban Line north of Tsuchiura and on the Mito Line.[3] Between 2011 and 2012, the fleet underwent a life-extension refurbishment programme, which involved replacing electrical and brake equipment.[5] These trains were originally equipped with Siemens GTO-VVVF propulsion systems, which were similar to the Keikyu 2100 series and also produced a "do-re-mi-fa-so-la-ti-do" scale when starting up. As part of the refurbishment, the propulsion system was changed to Toshiba IGBT-VVVF.
Between December 2014 and December 2015, all PS29 lozenge-type pantographs were replaced with single-arm pantographs.[4]

E501 SAKIGAKE train
editOn 25 October 2023, JR East announced that an E501 5-car train has been modified to become the special E501 SAKIGAKE train. This particular set received a new livery that inspires the image of red and white plum blossoms. The interior features tables for customers to eat and have drinks while onboard the train as well as a refrigerator that stores the cold drinks.[6] The set is numbered K754 and it entered service from 23 November 2023 on a special trip on the Joban and Mito lines between Mito and Yuki stations.[7]
