The flange, which often received a sidethrust of 5,000 lbs. or 6,000 lbs. under theten-ton car, has been accorded but scantconsideration, although the pressures andimpacts under the heaviest loads have to-day reached a magnitude of has been considered that the thicknessof flange which was originally adopted inthe early days of railroading cannot beincreased without interfering with guardrails and track. This idea, it has beendemonstrated, is not founded upon railroads are using flanges under. heavy equipment tliat exceed the M. C. gauge in thickness, and furtherthe question has been the subject of dis-cussion by a sub-committee of the Ameri-can Railway Engineering .Associationstrack committee. All the discussions, andthe sub-committees verbal report, wereentirely favorable to the proposition thatthe present M. C. B. flange can be in-creased 3/16 of an inch in thickness atthe rail line without interfering withpresent track conditions. This increase inthickness can be provided for by mountingthe wheels 3/32 of an inch closer to therail. As the matter now stands it is onlynecessarj- for the M. C. B. wheel com-mittee to say that an increased thicknessof flange will add an element of safetyto the wheel, and the American RailwayEngineering Association will meet themmore than half way. Attempts to thicken the flange abovethe rail line without any change at thebase line
