  From transfer-matrix calculation of localization lengths and their
finite-size scaling analyses, we evaluate critical exponents of the Anderson
metal-insulator transition in three dimensional (3D) orthogonal class with
particle-hole symmetry, class CI, as $\nu=1.16\pm 0.02$. We further study
disorder-driven quantum phase transitions in the 3D nodal line Dirac semimetal
model, which belongs to class BDI, and estimate critical exponent as
$\nu=0.80\pm 0.02$. From a comparison of the critical exponents, we conclude
that a disorder-driven re-entrant insulator-metal transition from the
topological insulator phase in the class BDI to the diffusive metal phase
belongs to the same universality class as the Anderson transition in the 3D
class BDI. We also argue that an infinitesimally small disorder drives the
nodal line Dirac semimetal in the clean limit to the diffusive metal.
