An energy management system for use with off-highway vehicles, including locomotives, that traverse a known course. The surface is comprised of a surface mesh of polygons. A non-linear and generally three-dimensional tongue shaped portion extends from the body at a junction defined between an extending portion of the handle and the door. In each pixel: each electrode includes an electrically conducting portion not superposed on other electrodes of the pixel and electrically connected to one interconnection hole filled with an electrically conducting material; and portions of an electrically conducting material are superposed approximately on each of non-superposed portions of electrodes. The carrier can be mineral oil or a mineral oil replacement. The guide includes a latch adapted to inhibit removal of the electronic card from the connector.
