A track spike (1) with a single or double shaft for wooden ties with spring loop (6), shaft (5) and crosspiece (4). The crosspiece (4), is, in its upper area via a bend (9) of the corresponding shaft portion in the direction of the rail foot (8), offset with resilience relative to the shaft (5). The crosspiece thus engages and retains the rail in position on the tie.
