A newly teased Loco DLCs by TSG have been broadly discussed on their Facebook page and an interesting point has been brought up with additional layers for these types of DLC. A question about whether the DB Br 420 could add layers to more than one route has been asked and the answer was basically that "you can't ask players to have more routes for the use of a mentioned DLC". (discussion in german below) On one hand, there is definitely a point to it - players shouldn't need to own 4 routes to get the loco DLC, on the other hand, I think there is definitely some possibility to improve in this regard. If the DLC could have a "main connected route", where you can expect the basic functionality (3 scenarios, timetable layer), then it should be possible to have "benefiting routes", where another layer would appear as well. Example: Br 204 has been criticised a lot for a very low amount of services (7 if I'm not mistaken). But if a 363 DLC added about 20 services to RSN and then smaller layers like the one of 204 to other routes, it would greatly improve the value of the DLC and would create a little benefit for people owning other routes, while not being mandatory. We've seen some reusability with 155 and 182, which however only substitute 185 on its services when MSB adds a new layer to new routes. This is not wrong but shunters are a different story as they cannot replace a mainline running loco so easily. This way the 204 is stuck with very little to do and other loco DLCs might have the same problems when restricted in such a way. It is also now clear that Br 420 will have only one route it will add to (probably HMA), while frequently appearing on at least three routes already in the game (HRR, SKA, HMA).
