Drift tube chambers are used for high resolution position measurements of charged particles in high energy physics. In the case of track reconstruction in two dimensions, for given geometry of a calibrated drift tube chamber, its output can be translated to a collection of triples, each one containing the coordinates of the wire of the drift tube crossed by a particle and the distance of the closest approach of a particle to the wire. The distance of the closest approach defines a drift circle which has the center at the wire and the radius equal to the distance of the closest approach. To reconstruct a linear segment of a track, a common tangent must be found to drift circles associated with that single track. In the study it is shown that this problem can be solved analytically.
