In the gameplay guide, you can a table showing which addons are required for which services, my question relates to duplicated train types, and the amount of services they add using the following picture for reference. Each of the 766.2 layers has 95 services, am I to take it from this that any combination of further addons will not add and further services for this train, as FTF already has 95 and that is the maximum?, or do the other combinations of addons add further services on top of the 95? Essentially, I want this route to have the maximum amount of available services, with the minimum amount of extra addons installed.
The FTF 766.2 will give you all services that are drivable using the 766.2. You won't get any further services from additional add-ons. I should add that I don't have the route either.
