Adopting a systems engineering approach to a feasibility study of a sidings development at the Midsomer Norton railway station.

It is planned to reopen Midsomer Norton railway station, which is a station on the Somerset & Dorset Heritage Railway Line, to traffic. As a first step, Midsomer Norton will be a terminus, and it is proposed to build sidings and a depot for the trains that terminate there. However, a ground investigation is essential before commencing construction of the sidings and the depot, as this is a vital part of any civil engineering process. The behaviour of the ground must be known in order for a structure to be supported by it; therefore, data from the ground investigation are used as reference for any kind of structure development. This study covers a site investigation that includes a desk study, walkover survey, sampling and laboratory testing in order to ascertain the feasibility of a suitable design. Moisture content testing, liquid limit and plastic limit tests, standard compaction testing, shear vane tests, and triaxial compression tests were carried out to determine the soil characteristics and to analyse the soil behaviour. A strong recommendation was made to follow a systems engineering approach in the construction phase, as well as in the design stage. The dependability of the system is ensured by the good use of V – process of systems engineering. [ABSTRACT FROM AUTHOR]
