So I loaded up TSW2 after the rush hour update and came across this notice saying that I haven't got the latest verson of 'NorthRhineMainLine'. This is baffling because such a route hasnt been released for TSW2. So that led me to think that this was a possible hint to a future route release. I've had a dig through Google at what this North Rhein Main Line is and couldn't find anything about it so I suspect its pure rubbish at this moment in time.
