Yes, I know that lots of threads about this topic already exist, but I'm adding to their number because of something I recently discovered and cannot remember having seen it noted in the forums. First, this is the Speedometer HUD I'm writing about, pictured here in a German engine: My light-bulb moment regards only the Grade Indicator portion of this HUD: And the key question is, as indicated, the direction of travel of the engine. Here's what triggered my light-bulb moment: after completing the necessary steps to set up the engine, including moving the reverser to forward, I turned on AFB, advanced the throttle a bit, and set the AFB lever to the current speed limit. Although the slope indicator seemed to indicate 2.0% down, acceleration was very slow. That's when, for some illogical reason, I pressed the 2 key, which showed me the rear end of the train. Why not the front end? Then I remembered the previous session, which involved preparing this train by coupling its rack of freight cars to the front of the engine. This session, however, began with the driver already seated and looking in the direction of the destination point. In other words, located in what was actually the rear cab of the engine! So what? So everything: that's what! In this case, the rear of the train was headed up, not down the grade (which was, in fact, steeper than 0.2%)! Now, some clever forum member will immediately claim that the engine indicator in the Slope (grade) indicator should, in a case such as this, flip around so that its front is pointing uphill. And that's a valid notion -- however, it doesn't happen to concord with how this indicator behaves in TSW2. This is one of those "Istanbul, not Constantinople" issues in which accepting what is makes more sense -- while driving, at least -- than griping about what one thinks should be.
