The applications range from fully automatic hump yard (ADT) operations to master/slave locomotive (MTT) operations. The communication of TH-AMR is remote controlled so that no wiring is necessary. ? The universal locomotive radio unit TH-AMR is a fully redundant radio control with the immediate evaluation of the received signal. ? The transmission part has a dual processing feature, which sends out the signal alternately. ? The dual layout of the processor has three advantages: increased availability of the terminal, increased safety of receiver signal, and increased range.
