Hopefully someone from Dovetail can answer this. Why aren't there any services for the two German shunters in the other German routes, other than their respective locations?
Well until they get around to adding some someday,you could create your own with senario planner.It's a option.
Not really. Since Scenario Planner currently only supports "stop at" commands, not couple/uncouple, one can't make meaningful shunting scenarios.
Didn't dtg say that they where working on improving senario planner and livery editor in some future update.
If you're on pc there's a mod which gives the shunters also eachothers services, so each shunter has 2 routes to work on, it's not much but it's something
