We report measurements of ${\ensuremath{\pi}}^{\ifmmode\pm\else\textpm\fi{}}{K}^{\ifmmode\pm\else\textpm\fi{}}$, and $p$, $\overline{p}$ inclusive cross sections and fractions in ${e}^{+}{e}^{\ensuremath{-}}$ annihilation at $\sqrt{s}=29$ GeV, for the momentum interval $0.01&lt;z=\frac{p}{{p}_{\mathrm{beam}}}&lt;0.90$. The analysis is based on approximately 70 ${\mathrm{pb}}^{\ensuremath{-}1}$ of data collected with the $\frac{\mathrm{TPC}}{2\ensuremath{\gamma}}$ detector facility at the SLAC storage ring PEP. Detector upgrades result in significantly improved momentum coverage and precision of the data, compared to previous measurements.
