I have been playing TS / TSW now for about 10 years and I always wonder why certain bugs are never fixed. I prefer German routes and there are many issues where speed signs for upcoming speed reductions were simply not placed and/or when they were placed, they are wrong. Another issue is that PZB often does not work correctly. It depens on the route, some routes have less PZB issues than others. For example, a "amber" light indicates that the next main signal will show the stop aspect and when driving with PZB enabled, you have to acknowledge this signal and slow down. This will usually activate the PZB and the "85" light will flash. Very often, the light will not flash as the magnets on the track seem to be not active. I recently had an issue with the ICE 1 schedule service on the current "Linke Rheinstrecke" route: A speed change to 120 km/h was indicated and the speed was even slowed down to a lower speed (i think it was 60 km/h) but there was neither a sign for the speed change nor was there a signal aspect. This is just plain wrong. My experience is that there are relatively many erros on (German) routes but they are never fixed. I am active in a major german message board and other members stated that they issue tickets for the above mentioned and other errors but there is no response. This is pretty annoying and I have become extremely disappointed within the last years. I love to drive without a HUD but if you rely on the signs/signals you might be either too fast or too slow because lots of indications are simly missing. Another thing is that especially older rolling stock has broken sounds now. I loved the BR 155 but the sounds in the cab have been nearly silent since a previous update. Other rolling stock also has sound issues. But I have learnt that DTG seems not to be interested to fix anything. Why is that? Are they just lazy? Why do they not care? Why have some errors in signalling and other aspects been in the game for years and no one cares for bugfixing albeit tickets are issued for that? Are they not testing their routes and cabs properly? It seems that quantity is more preferred than quality. Greetings Chris
