Russell considered electricity as the means by which Jehovah will bring the blessings of the New System. He viewed things like trains, light bulbs and radio as a foretaste of the new system.
However, the current "official" view is IMHO that all people will live as farmers. Just look at the various pictures of paradise in the publications: Have you ever seen a car, a train, a plane, an electrical outlet, a cup of coffee, a computer or a telephone?
