Rusich also features a corridor connection, allowing passenger access between two contiguous cars. They are currently assigned to the metro lines including Arbatsko-Pokrovskaya Line, Filyovskaya Line, Koltsevaya Line and Butovskaya Line of Moscow Metro, and all lines of the Sofia Metro in Bulgaria. Currently, there are four types of Rusich rolling stock: 81-740/741, 81-740.1/741.1, 81-740.4/741.4 which are used in Moscow Metro, and 81-740.2/741.2, 81-740.2B/741.2B which is technically adapted and designed for Sofia Metro. Automatic control system and universal control panel was designed by Tikhomirov Scientific Research Institute of Instrument Design (NIIP). External links
