Errr, DB, how do you even calculate this one?

Public transport in Luxembourg is FREE

And Troisvierges and Luxembourg are both, errr, in Luxembourg 🤯

@jon pretty sure the only ticket the DB knows about for this is the Saar-Lor-Lux ticket (a ticket obscure enough the Wikipedia page still prices it in Marks) and is simply not aware of the “ticket” known as free travel
Probably Saar-Lor-Lux yes. CFL no longer publishes any TCV whatsoever.
