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, ". 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
- * Tokyo Metro Fukutoshin Line: Express
- * Tōkyū Tōyoko Line and Minatomirai Line: Limited Express
- Tōbu Line system: Ogawamachi / Shinrin-Kōen - Motomachi-Chūkagai
- * Tōbu Tōjō Line: Rapid Express

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.
