प्रयागराज एक्सप्रेस - जो भी हो तुम खुदा की कसम; लाजवाब हो

The Boards of this Train have been Changed and new yellow colored Boards have been fixed. But in all the new boards, from the writing "Howrah - Barbil", Howrah looks dark and new while Barbil has faded away and looks as if it was written long ago. How can only one side i.e. which side Barbil has been written, fade away so soon while the side where Howrah is written remain new and bright from one board?
