The TH Liner (THライナー) is a limited-stop "Home Liner"-style service to and from Kuki Station in Saitama on the Tobu Isesaki Line operated by the private railway operator Tobu Railway in Japan since June 2020.

Service outline

TH Liner services operate in the mornings on weekdays and weekends in the "up" direction (two services) from Kuki in Saitama Prefecture to Ebisu in Tokyo, and in the evenings (weekdays and weekends) in the "down" direction (five services) from Kasumigaseki to Kuki.^[1] In the up direction, a supplement of 580 yen (300 yen for children) is required for travel between the serviced Hibiya Line stations and Sengendai station, and 680 yen (350 yen for children) beyond as far as Kuki station. No supplementary fare is required for passengers boarding the service between Kasumigaseki to Ebisu.^[1] All seats are reserved, and the supplementary tickets indicate which car to ride in.

Rolling stock

TH Liner services are operated by a fleet of 70090 series 7-car electric multiple units (EMUs). Like their 50090 series counterparts, 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 TH Liner services.^[1]

Station stops

Morning "Up" services start at Kuki and terminate at Ebisu. Evening "Down" services start at Kasumigaseki and terminate at Kuki. For the morning "up" services, the service only picks up passengers between Kuki and Shin-Koshigaya. Between Ueno and Ginza, passengers can only get off the train. Starting at Kasumigaseki, passengers may get on and off at any of the serviced Hibiya line stations until the terminus at Ebisu. For the evening "down" services, passengers can only get on the train at the Hibiya Line stations starting at Kasumigaseki. Starting at Shin-Koshigaya, passengers may only get off the train until the terminus at Kuki.
