The atmospheric railway has probably received its death-blow by the abandonment of that mode of traction by the South Devon Railway Company, after having spent £300,000 in experimenting upon it. The system is found to be too expensive. It costs £108 to earn £100! No more need be said about it. Punch places it in his obituary of this week.
