# TJ Liner

The TJ Liner (TJライナー, Tī Jei Rainā) is a limited-stop "Home Liner"-style service to and from Ikebukuro Station in Tokyo on the Tobu Tojo Line operated by the private railway operator Tobu Railway in Japan since June 2008.

## Service outline

TJ Liner services operate in the mornings on weekdays in the "up" direction (two services) from Shinrinkōen in Saitama Prefecture to Ikebukuro in Tokyo, and in the evenings (weekdays and weekends) in the "down" direction from Ikebukuro to Shinrinkōen or Ogawamachi. In the down direction, a supplement of 310 yen is required for travel from Ikebukuro, but no supplementary fare is required for passengers boarding at other stations along the line. In the up direction, a supplement of 410 yen is required from all stations (310 yen from Fujimino). Seats are not reserved, but the supplementary tickets indicate whether passengers should ride in the front or rear five cars of the train. At Ikebukuro Station, passengers board from platform 5, which is normally used only for passengers alighting from other services.

### Weekdays

Four morning up services (Nos. 2, 4, 6 and 8) operate from Shinrinkōen to Ikebukuro, departing at 06:11, 06:27, 07:52 and 08:18, respectively. In the evenings, 13 down services (Nos. 1 to 25) operate at half-hourly intervals between 18:00 and 24:00 from Ikebukuro to Ogawamachi (Nos. 23 and 25 terminate at Shinrinkoen).

### Weekends

At weekends, nine evening down services (Nos. 1 to 17) operate at half-hourly intervals between 17:00 and 21:00 from Ikebukuro to Ogawamachi.

## Rolling stock

TJ Liner services are operated by a fleet of six 50090 series 10-car electric multiple units (EMUs). These sets are unusual in having rotating pairs of seats allowing them to be used with longitudinal seating on regular daytime services, and with transverse seating on evening TJ Liner services. When configured in transverse mode, the rows have a seat pitch of 1,000 mm (39 in). Some trains are sent to Ikebukuro from Shinrinkōen as limited-stop Rapid Express services, which also operate with seats in the forward-facing configuration.
Since March 2016, the automated on-board passenger announcements in Japanese use the voice of TV presenter Tomomi Kuno [ja].
