    摘要: A rail fastener includes a spring anchor plate provided with a longitudinal slot dividing the plate into a rail engaging section and a tie retainer member engaging section. A retainer member, fixably disposed relative a crosstie, clampingly engages the tie retainer member engaging section to bias the undersurface of the rail engaging section against the upper surface of the rail base flange.
