A Model Railroad Fast Clock is a specialized timing system used in model railroading to simulate the passage of time at an accelerated rate, ensuring realistic train operations and scheduling within a compressed session. Unlike a standard clock, which runs in real time (1:1 ratio), a fast clock operates at a chosen speed ratio—commonly 4:1, 6:1, or even higher—allowing an hour of simulated time to pass in a fraction of actual time. For example, setting the session length to 4 hours (6:1) means that every 1 real minute equals 6 Fast Clock minutes. This system is essential for model railroaders who adhere to prototypical timetables and dispatching methods, as it enables the execution of complex train schedules, meets, and station stops within a manageable session length. This online fast clock can be displayed on tablets placed around an entire layout to maintain consistency among operators, ensuring that train movements, crew changes, and yard operations all align with the accelerated time frame.
