F Liner

is the name for the fastest through service train among five railway companies: the Tobu Railway, Seibu Railway, Tokyo Metro, Tokyu Corporation and Yokohama Minatomirai Railway.

This name is trademarked by the aforementioned five companies (No. 5885630).

Service pattern The name "F Liner" is given to trains under the two route systems explained below. The service type of trains may change once across boundary stations for two different lines. Therefore, systematically, the name "F Liner" will be added before the service type; this means all F Liner trains are referred to as "F Liner, (Service type on current line)". For instance: Within the Fukutoshin Line → "F Liner, Express", bound for Motomachi-Chūkagai; Within the Toyoko Line → "F Liner, Limited Express", bound for Shinrin-Kōen.

Seibu Line system: Hannō / Kotesashi - Motomachi-Chūkagai Seibu Yurakucho Line and Ikebukuro Line: Rapid Express (快速急行) Tokyo Metro Fukutoshin Line: Express (急行) Tōkyū Tōyoko Line and Minatomirai Line: Limited Express (特急) Tōbu Line system: Ogawamachi / Shinrin-Kōen - Motomachi-Chūkagai Tōbu Tōjō Line: Rapid Express (快速急行) Tokyo Metro Fukutoshin Line: Express (急行) Tōkyū Tōyoko Line and Minatomirai Line: Limited Express (特急)

Within the Fukutoshin Line, the Tōyoko Line and the Minatomirai Line, four F Liner trains operate every hour at 15-minute intervals during daytime: two operate on the Tōbu Line system from/to Shinrin-Kōen, and the other two operate on the Seibu Line system, with one operating from/to Hannō, and the other from/to Kotesashi, each operating at 1-hour intervals. For northbound trains on weekend mornings, only one F Liner train operates every hour which terminates at Hannō.

The longest distance travelled for an F Liner journey is , from Ogawamachi to Motomachi-Chūkagai.

From 18 March 2023, F Liner services now operate as Rapid Express services on the Tobu Tojo Line instead of Express services, skipping Shiki and Fujimino. Previously, F Liner trains did not operate as the fastest possible through service on the Tojo Line, as faster Rapid Express through services ran alongside the F Liner's Express services.
