Martin 40 Bus Thanks and your issue had been forwarded.
Kadimbey Your guess is right, at some circumstances. There're some special things coming, but I can't confirm nor deny anything at the moment.
NateSakana 'X' for express service is especially for Flixbus mode. As its name 'shuttle', we just couldn't introduce the 'express' concept here.
