Today railway transport is quiet different than in old times. There are many thousands of locomotives, hundreds of thousands of cars and oil-cisterns. The trains today go much faster. The whole wagon fleet was fitted with continuous brakes, and hundreds of thousands of wagons were equipped with automatic couplings. Many old lines were improved and electrified and the use of diesel traction was begun. Heavy rails were laid extensively and a substantial mileage was equipped with automatic block signaling.
