The scope of this paper is to recount the development of segmental linings used in tunnel construction, starting with its inception as an improvement to the brick-lined tunnel approach of Brunel in England and moving through the history and development to the present day, before finishing with a few insights into what the future might hold._x000D_
The paper also discusses the motivation for the relatively recent move towards replacing conventional steel reinforcing cages with steel fibres and the reasons why steel fibre reinforced concrete (SFRC) is rapidly becoming the material of choice for manufacturing precast concrete segmental linings.
