This user’s guide will walk you through operating and programming Tsunami2 to its full capacity. Default Function Assignments Table A.
  • Page 6 Signaling can make your operating sessions more fun! Engineers signal to notify passengers, crew, and other trains of common locomotive movements, such as stopping, moving forward, backing up, and approaching grade crossings. Tsunami2 provides three functions for signaling. Use F2, F3, and F9 to signal prototypically while you operate, as described below.
  • Page 7 To simulate this reality, Tsunami2 is equipped with automatic Dynamic Digital Exhaust (DDE) and provides F5 (RPM+) and F6 (RPM-) for manual control. Dynamic Digital Exhaust is one of the most innovative features in Tsunami2, and automatically adjusts the volume and engine RPM schedule to simulate the locomotive producing a range of power during operation.
