The line between München and Nürnberg is one of the few really high speed lines in Germany. Between Nürnberg and Ingolstadt the trains run at max. 300 km/h. The line is at 170.8 km, and is around as long as the Hamburg-Hannover line. The line shouldn't be too hard to make, as many of the trains that are used are already made by DTG (Some in other liveries).
I think this line is ideal to make because it is a high speed line, but also includes S-Bahn, RB, RE and IC trains. I don't know too much about the freight trains on this route.
The route is fully electrified, and is one of Germanys most important lines, as the line where all high-speed trains come to Munich. Before the new 300 km/h line between Nuremberg and Ingolstadt all ICE-trains went along the line between Munich and Augsburg.
Trains to be included with the route:
BR 101 with InterRegio-coaches and IC-coaches:
The BR 101 is probably the most used German train in TS and probably comes with all routes. On this line it runs as an RE-train with Regio-coaches. They (on the outside) are basically the new TS IC-coaches but with the usual DB red livery instead of the white. They can be made from scratch, but I think the other way would be easiest. Although a driving trailer being made could be nice. This train is called the Münich-Nürnberg Express, and runs, as the name says, between Munich and Nuremberg.
The IC-coaches are just the ones that are already in use with the BR 145. In this route the loco should be the BR 101 (Driving trailer being made also)
ICE 3:
The ICE 3 is used on some routes, and in this route it can be used to its maximum potential with 300 km/h speed. There isn't really anything else to say about it, but it is a must that it comes with the route.
DLC-trains:
BR 423:
Munich S2 between Peterhausen (Oberbayern) and Munich Hbf (On the line)
ICE 1:
Common High speed train on the route
BR 143/BR 146
RB-train between Allersberg and Nürnberg. It has n-coaches with it and a 480.3 driving trailer. It could be a nice little DLC to play with on this route. (The BR 143 has a max speed of 140 km/h). Also this could make way for a newer version of the now pretty old 143 on TS.
I hope that TS makes this route and I am sorry if some of this was wrong. I don't know much about this route, but i thought it was a nice one. I hope you enjoyed reading though :)
