First of all this internet-packet-routing-like way of transporting goods would work only if almost every town in America had rail passing through it, or at least very near it, which isn't the case. Secondly if such a rail network were to be constructed it would pay off to just have it electrified and use these carts without a battery. Until that day what rail needs is maintenance, expansion and usage, not these silicon valley pipe dreams.
