The CDF and D0 collaborations have analyzed up to ~200 pb-1 of
Run 2 physics data to measure W production properties such as the W cross
section, the W width, lepton universality and the W charge asymmetry. From
the cross section measurements, CDF obtains a lepton universality of
g_mu/g_e = 0.998 +/- 0.012 and g_tau/g_e = 0.99 +/- 0.04 and an indirect W
width of Gamma(W) = 2079 +/- 41 MeV. D0 measured the W width directly and
finds Gamma(W) = 2011 +/- 142 MeV. CDF has estimated the uncertainties on
the W boson mass measurements in the electron and muon decay channels and
obtains an overall uncertainty of 76 MeV.
