Abstract (en)
[origin: EP1593576A2] The separation between two railway vehicles on the same line is detected by a rectangular pickup loop with a couple coil (5) jointly formed by two the two rails and respective axles. Together these operate as a strongly scattering transformer. The primary side of the transformer is formed by the couple coil. The secondary side is formed by a rectangular electrical conducting loop. A flow of current in the coil is associated with magnetic flux, with flux linkage to the loop formed by the axles. The coil is linked to a separation display instrument.
