1. A rail car data signal coupling structure, comprising:

  • a first electrical coupler head attached to a mechanical coupler of a first rail car;

    a second electrical coupler head attached to a mechanical coupler of a second rail car, the mechanical coupler of the first rail car able to couple to the mechanical coupler of the second rail car;

    a first data coupling unit located in the first electrical coupler head;

    a second data coupling unit located in the second electrical coupler head, wherein, when the mechanical coupler of the first rail car is coupled to the mechanical coupler of the second rail car, the first data coupling unit and the second data coupling unit are located in non-contact proximity to one another to provide non-ohmic coupling of data signals; and

    at least one signal equalization circuit, electrically connected to at least one of the first data coupling unit and the second data coupling unit, the at least one signal equalization circuit operating to provide frequency equalization to support baseband data communications up to a specified data rate through the non-ohmic coupling.
