First of all, thanks to Matt for the tutorial on German signalling, PZB, LZB and more. For me most of the contents was not very new,so I especially liked the part on LZB and AFB in the ICE3. Matt, you asked for feedback on the tutorial style. Generally I do not like long video tutorials a lot. The main reason is that it is time consuming to find the information back. For me the best way is: - A short explanation/demonstration - A text (illustrated) as a reference document so you can read the it again - Short game play exercises, so you can practice yourself. In this specific case, I would have split it in following parts: - German signals (maybe even two separate tutorials), with a short game tutorial to show situations in game. This is easy to do. Park a train on the track, let the driving train approach it. - ICE3 AFB setup and teardown. - PZB O-mode, maybe a tutorial just to set it up and drive away. - LZB in a separate tutorial - A very short one on SIFA - PZB kind of repeat for the BR422 - PZB in U mode for a freight The excercises can be built using the scenario planner (I think), you only will miss instructions and comments during game play. Some tips: to practice PZB Rhein-Ruhr Osten is a perfect route. You can use the RE drives (need MSB route). For some reason at most stops the signals are set red till you picked up passengers, so each station is an opportunity to try PZB. Also both near Hagen and Wuppertal there is a speed reduction that requires you to acknowledge PZB. In the ICE3 to turn on PZB/LZB without leaving the driver seta, you can use the right arrow key, which will cycle you to this cabinet. Much easier than standing, crouching etcetera.
