The Tobu N100 series (Japanese: 東武N100系, romanized: Tōbu N100-kei), branded Spacia X (スペーシアX),[3][4] is an electric multiple unit (EMU) train type operated by the private railway operator Tobu Railway on limited express services in Japan since 15 July 2023. A total of four 6-car sets are to be built by Hitachi to replace the ageing 100 series EMUs which have been in service since 1990.[5]

History

Details of the N100 series were first announced on 11 November 2021. The N100 series is intended to succeed the 100 series Spacia as Tobu's flagship limited express fleet.[5] Production of the fleet began in fiscal 2022,[6] with the first two sets, N101 and N102, being delivered from Hitachi's Kasado plant from 5 March 2023.[7]

The N100 series fleet entered service from 15 July 2023.[3][4]

Design

The N100 series sets are part of Hitachi's A-train family, and use aluminum body construction.[8]

Exterior

The N100 series sets are painted in a shade of white[9] that takes influence from the color of the Yomeimon gate at the Nikko Tosho-gu shrine.[10] The end cars are fitted with hexagonal side windows, whose frames are inspired by the Japanese "kumiko" woodworking technique.[10][2]

The train ends each feature an LED panel with 39 LEDs, functioning as a headlight and taillight cluster; when switched on, the headlights form a "T" shape. External LCD destination displays are located at the sides of each car.[11]

Interior

The interior consists of the following accommodations:

  • Cockpit Lounge (car 1): The Cockpit Lounge consists of sofas and lounge chairs. Two lounge chairs face the driver's cab, allowing passengers a front view. A bar, which serves beer, coffee, and snacks, is located at the rear of the Cockpit Lounge. Car 1's vestibule features an artificial skylight.[2]
  • Premium seating (car 2): Seats are arranged in a 2+1 abreast configuration with a seat pitch of 120 centimetres (47 in).[12] The seats are colored orange, which was chosen to make the seats stand out from the dark grey flooring. They also incorporate a back shell structure, which Tobu Railway states allows for reclining without impacting passengers in the rear.[13]
  • Standard class (cars 3–5): Seats are arranged in a 2+2 abreast configuration with a 110-centimetre (43 in) seat pitch, the same as that of the outgoing 100 series.[13] Cars 3 and 4 consist of standard class accommodation throughout (56 seats each), and car 5 has 18 standard class seats, wheelchair spaces, and two 2-person semi-compartmentalized seating bays.[2]
  • Cockpit Suite (car 6): Situated behind the driver's cab, the Cockpit Suite is an 11-square-metre (120 sq ft) space which seats up to seven passengers (four seats and a three-person sofa). The suite and the driver's cab are separated by a glass barrier, also allowing passengers a view from the front.[14] Also featured in car 6 are four 4-person compartments, with sofas that form a "U" shape.[2] The compartments are situated directly behind the Cockpit Suite.[14] Like car 1, car 6's vestibule features an artificial skylight.[2]

Operations

The N100 series fleet operates between Asakusa and Kinugawa-Onsen (or Tobu-Nikko) stations on the Tobu Skytree, Nikko, and Kinugawa lines. They operate two round trips per day (four on Thursdays, Fridays, Saturdays, and holidays).[15]

Formation

The N100 series sets consist of four intermediate motored cars with non-powered (trailer) end cars. They are formed as shown below.[2]
