There are over 35 differences between class I chain railways and Class II china railway and/or the American Railway Engineering and Maintenance-of-Way Association standard . These include classifications (role, speed, tonnage, trailing load, etc), safety (safety coefficient, level crossings), geometry (curvatures, gradients etc.), subgrade/ embankment treatment (width of top embankment, subgrade layer, settlement per year and total settlement, etc.), superstructure (Rails, fastener, bridge/ pier, axle load etc.) and ballast thickness and type. All these impact on investment cost and operation and maintenance costs
