OMSI 2: The Bus Simulator is widely regarded as the most authentic bus driving simulation available, praised for its mechanical depth and the meticulous recreation of real-world routes. At the heart of this realism lies a small, often misunderstood, but critical component of the in-cab experience: the IBIS system . For the uninitiated, IBIS codes might appear as just another set of numbers to type. However, for the dedicated virtual driver, understanding and correctly using these codes is the fundamental difference between a casual drive and an authentic simulation of a day in the life of a bus operator. What is IBIS? IBIS is an acronym for Integriertes BordInformationsSystem (Integrated Onboard Information System). In real-world public transport, particularly in German-speaking countries like the ones featured prominently in OMSI 2 (Berlin, Hamburg, Gladbeck), IBIS is the centralized computer system that automates many of the driver’s non-driving tasks. It controls the passenger information displays (destination signs and LED matrixes), announces upcoming stops over the internal PA system, and logs route and trip data for operational tracking.
In OMSI 2 , the virtual IBIS interface—accessible by pressing the Ctrl + Keypad keys or by physically clicking the buttons on the in-cab IBIS terminal—replicates these core functions. Without IBIS, your bus would operate in a silent, uninformative vacuum. Passengers wouldn’t know where the bus is going, stops wouldn’t be announced, and the simulation’s internal passenger logic (which depends on correct route coding) would fail, leading to confused, non-boarding AI pedestrians. The IBIS code in OMSI 2 is typically a multi-digit number, most often a 5-digit line code or a 3-4 digit route/course number. The exact format varies slightly depending on the map and bus add-on, but the most universal standard follows the pattern: omsi 2 ibis codes
