A selectively tuned train coil is provided for each digit of a train's identity number, mounted to successively couple, in descending digit order, with coils of the wayside receiving apparatus. Each digit successively received by the wayside apparatus is immediately translated from decimal to a two-out-of-five code format and temporarily registered in a separate bank of code bit relays. This identity code is transmitted to a remote location including a route type interlocking control system. Each identity code is received and cascaded through a series of relay storage banks, reaching the final bank when the corresponding train is next to arrive at the interlocking. The code readout circuit network, which automatically selects the desired route control relay, includes a code format checking matrix, to assure that two but only two bits are actually registered for each identity digit, and a translation matrix to reconvert the unit digit code to decimal form.
