Steam Niddertalbahn Mastery Unknown Tasks

Something is missing ... like what do I actually have to do to unlock T2?

 

I am getting the checklist, but no matter what I do Tier 2 seems never to register anything betond 2 timetables and 108 km driven.

 

Haven't got it yet. Sometimes new mileage doesn't get added, sometimes it jumps back.... I've done many more miles than the counter says.

 

Drove a few more services, Mastery works

 

How many did it take you?

 

3

 

it indeed sometimes recognises the distance and sometimes it doesn't. just do a few more services and you'll get the mastery

 

It doesn't work. 18 scheduled journeys and it doesn't count.

 

Same here. Stuck with about 89 kilometres and neither timetables nor scenarios nor free roam seems to register for additional mileage,
