In addition to this the outside rail was elevatedabove the inner one on each track. The theory that thecause of corrugation is the chattering of the rollers in theprocess of making the rails and that the corrugations reallyexist before a car has been run over the rails, can hardlyhe reconciled with the fact that the lengths of the corruga-tion waves vary apparently with the speed of the c
