Lpon this point Mr.Vauclain, of the Baldwin Locomotive Works, writes:I am inclined to think that on extra large enginesthe east iron deck plate in front of the cylinders is agood thing in the absence of a foot plate, but betterstill, add the foot plate to be done with it. In recommending designs of cylinder fastenings dis-tinction should be made between passenger and freightlocomotives, even where the cylinder power is thesame. Passenger locomotives exert their full tractivepower only at starting and the cylinder fasteningsare not exposed to as severe continuous strains asthose of freight engines. Passenger locomotives, as arule, also receive better care. Large boiler poweris of such supreme importance in passenger locomo-tives that the weight of all other parts must be re-duced as much as possible. These considerations, itis believed, justify the use of lighter cylinder fasten-ings than would be a good practice for freight. Thisis especially true for eigh
