1. A portable device that is fixed onto a single rail of a rail track for measuring track deflection, comprising:
an attaching mechanism for fixing the device onto the single rail;
a plurality of lasers for measuring a vertical track deflection and a horizontal track deflection;
a temperature sensing device for measuring a temperature of an ambient temperature and a rail temperature;
a location sensing device for determining a location of the device; and
a solar panel for providing continuous power to the device.
