ABSTRACT:
Apparatus enabling electrically-isolated transfer of signal data between rail cars connected in tandem in the direction of intended travel. Cable-free space is established between optical transmitter and optical receiver means enabling automatic optical coupling and decoupling. Means are provided to maintain signal intensity and accuracy of signal data transfer notwithstanding changes in alignment and spacing between transmitters and receivers during rail guided travel.
