Dewatering requirements for new railways are mainly associated with tunnel approach structures, deep cuttings and underground stations. Also over time older railway infrastructure will require repair or updating. These projects are particularly challenging as it is usually necessary to avoid or minimise impact on the existing live train services while the works are undertaken. Even for new build works adjacent existing live railways are often in close proximity.
