The 218 is a monster yes but there is a bigger version of the BR216 which is the mother of the 218. This big locomotive is numbered 320 001 or V320 001. Its basically a 216 with 6 axles and 2 engines. Even the DB was happy with it just this one locomotive was built. Its still fully functional today and also driveable
Joe, apparently to what @Spursrail96 said about this loco and route, he said that unfortunately this route will not and I repeat will not receive any updates or TOD4 updates like the WSR had or other TSW 4 routes ...
remember those updates take a huge amount of time which dtg don't always have the time or staff to do. It's not just a simple button unfortunately. A dev would have to do it in their own free time
