On site and pre-commissioning test phase
Minor safety issue
Where a design involves complex signalling arrangements, may be
beneficial to involve the designing engineer during the final
onsite field testing phase as they have the best understanding of
the interlocking principles. This places them in a strong position
to identify any design omissions or deficiencies that may not have
been evident during earlier phases of a project.
