Not likely in a multi line haul...

The originating railroad's locomotives run through to destination. Or exchange of power at the interchange point is well-coordinated. In any case, transit times are likely no more than a week in each direction (and could be as little as four or five days). Only stops made are for crew changes and to wait for other train traffic.
