The third improvement of the positions and proper motions for the Ondřejov PZT star list is based solely on PZT observations in the interval 1973 - 1986. Within this period more than 44 thousand star transits on 1546 nights were observed. The mean epoch of the resulting catalogue PZT 86 is 1981.56, the average standard errors in right ascension and declination, referred to this epoch, are equal to ±0.0015s and ±0.017arcsec, respectively. The proper motions in right ascension and declination were obtained with an accuracy characterized by the average standard errors of ±0.051scy-1 and ±0.57arcseccy-1, which will cause the standard errors in position to increase to ±0.0096s and ±0.106arcsec by the end of the century. The comparison of the new catalogue with the preceding two (PZT 78 and PZT 83) and AGK 3 reveal important systematic errors in AGK 3 that grow with time.
