Before revision:  Analytical results are obtained for mean cargo velocity , diffusion coefficient and the average force experienced by each motor for arbitrary N, and compared with numerical simulations. The expansion procedure also allows us to quantify load-sharing features among the cargo-bound motors.
After revision:  Analytical results are obtained for mean cargo velocity , diffusion coefficient and the average force experienced by an individual motor and quantitatively characterize the load-sharing features among the cargo-bound motors.
