  We investigate the transport properties of Chern insulators following a
quantum quench between topological and non-topological phases. Recent works
have shown that this yields an excited state for which the Chern number is
preserved under unitary evolution. However, this does not imply the
preservation of other physical observables, as we stressed in our previous
work. Here we provide an analysis of the Hall response following a quantum
quench in an isolated system, with explicit results for the Haldane model. We
show that the Hall conductance is no longer related to the Chern number in the
post-quench state, in agreement with previous work. We also examine the
dynamics of the edge currents in finite-size systems with open boundary
conditions along one direction. We show that the late-time behavior is captured
by a Generalized Gibbs Ensemble, after multiple traversals of the sample. We
discuss the effects of generic open boundary conditions and confinement
potentials.
