In Dresden-Riesa Route. 363 is hard to brake, strange operating feel. It should add "spring", let brake "keep", not continue to increase. I only use mouse to switch quickly. How to use gamepad to control brake? By the way, which German DLC do you recommend. I had: Dresden-Riesa Kassel-Würzburg How about Koln-Aachen? Add ICE in Dresden-Riesa?
I think the best German route before Dresden was Ruhr-Sieg Nord. Main-Spessart Bahn is really good also. 363: hard to get used to the throttle- which is a "hold to increase, release to stop increasing" sort. In that way it's kind of like the brakes, which are manually lapped; you'll find similar ones on the (UK) 101, the F7, the Caltrain F40 and so on. They take some practice to get used to; I would recommend watching the equalizing reservoir to judge the application. Can't help with the controller question.
Rro is a nice scenic route. It's all the way from tsw2020 but I found it to be really scenic compared to other tsw2020 routes. The g6 can also be bought for extra services. Munchen Augsburg is a good route too. You get the 423 and another ice3. You get lots of layers from other routes. Dresden chemitz is okay if you like tilting german trains. It's quite scenic and challenging and steep. Ska adds ice services to dra. I would recommend you pick up the new journeys expansion as that adds in a lot of services to the route. Rsn is if you like a freight corridor. There's some passenger runs but not a whole lot. It's scenic and on the slower side, but fast compared to us freight routes. Bro is nice if you like a busy route. If you own skw, dcz and any route with a shunter, you get layers with the ice1, 612 and 363. Lots of ai only freight traffic as well. The recent Mainz-Koblenz is nice but still new so there are still some bugs. You get a 110 and 103 which are iconic locomotives. It is scenic and a good length run. Msb is also a nice route. It's unique in that you have banking services to go up the spessart rampe. hrr is great too. It is short but busy. You can also buy the 101 which layers onto several german routes such as ska with new journeys expansion, skw, dra and bro The upcoming niddertalbahn releasing this week is really good. Extremely scenic, custom assets, historically accurate. It's only single track and not busy but it goes the extra mile to make it really good.
They have helped dtg with most german content. For example the ice trains, 612, 363, 101 were all assisted by Maik who is the head of TSG. They have made a standalone loco dlc known as the g6. They are releasing niddertalbahn this thursday and working on other content such as the 420.
