Summary
S-Train service was first announced by the four operating companies on 16 June 2016, with further details being given on 10 January 2017. The service is centered on Seibu Railway, and uses their 40000 series trains. Within the four operating companies, the S-Train is the first-ever reserved-seat train to operate on the Tokyu and Minatomirai railways. The name "S-Train" was used by the 4 companies during trademark registration on 21 November 2016, and has been trademarked since 21 April 2017 (No. 5941839). The "S" in "S-Train" stands for the following: * Scene: Used in different scenarios, like commuting to work, going to school or going on outings * Seat: Comfortable reserved seats * Seamless: Seamless journey thanks to through service without interchange * Seibu The four terms above all start with the letter "S", hence the name "S-Train". The logo has three different colours, each with unique meanings. The upper part of the "S" is coloured green, signifying the greenery alongside the Chichibu Line; the lower part of the "S" is coloured blue, signifying the Minatomirai Line, whose signature colour is also blue; and the text "S-TRAIN" is grey, signifying the urbanisation around Shibuya and Toyosu, which the train serves. In terms of service type, the S-Train is uniquely positioned. It is positioned lower than Seibu's limited express (the ''Red Arrow'') on the Seibu service hierarchy, but is placed higher than Tokyu's limited express (which does not charge extra fees) in Tokyu's service hierarchy.Services
Train operation differs between weekdays and weekends. The direction is denoted by "Up" and "Down", where trains for Toyosu or Motomachi-Chukagai are "up" and trains for Chichibu or Tokorozawa are "down". This is based on Seibu's standards, in which southbound services are "up", and northbound services are "down". The S-Train follows Seibu's standards because it is the main operator of the service. A further reason for using Seibu's standards is to prevent confusion, as Tokyo Metro and Tokyu use reversed denotations of service direction compared to Seibu. Since all seats on the S-Train are reserved, there are special conductors (specially called "Train Crew" within Tokyu sections) to make sure passengers have purchased seat reservations. Because of this, the S-Train differs from regular Tokyo Metro services, as each S-Train is only operated by one person.Weekdays
On weekdays, S-Trains operate mainly to serve commuters. They run betweenWeekends
On weekends, S-Trains operate mainly to serve visitors. They run between Seibu-Chichibu and Motomachi-Chukagai, on the Seibu Chichibu and Yurakucho Lines, the Tokyo Metro Fukutoshin Line, the Tokyu Toyoko Line, and the Minatomirai Line. The section is 113.8km, which is the longest distance of any Tokyo Metro through train service. There are 2 southbound trains (one originating from Seibu-Chichibu, the other from Hanno, all for Motomachi-Chukagai), and 3 northbound trains (one to Tokorozawa, one to Hanno, and one for Seibu-Chichibu, all originating from Motomachi-Chukagai) per day on weekends. The southbound train from Hanno and the northbound train to Seibu-Chichibu are the only weekend S-Trains that operate in the morning. All other S-Trains operate in the evening. Passengers cannot board S-Trains at Ikebukuro.Stations served
