  We study the dynamics of the quenched Anderson model at finite temperature
using matrix product states. Exploiting a chain mapping for the electron bath,
we investigate the entanglement structure in the MPS for various orderings of
the two chains, which emerge from the thermofield transformation employed to
deal with nonzero temperature. We show that merging both chains can
significantly lower the entanglement at finite temperatures as compared to an
intuitive nearest-neighbor implementation of the Hamiltonian. Analyzing the
population of the free bath modes -- possible when simulating the full dynamics
of impurity plus bath -- we find clear signatures of the Kondo effect in the
quench dynamics.
