The main line between Manchester and Crewe, British Railways, passes through a section subject to serious subsidence caused by brine extraction. The average yearly subsidence is 8 in. The design of the overhead line equipment to maintain the contact wire within the maximum and minimum heights above rail level is discussed and is illustrated. The track can be lifted for a period of four to six years before the foundation for the overhead structure will need to be lifted.
