Factors required to be well understood before taking up planning : trains is not only about safety with speed and smooth running as primary concern but also about professional and financial efficiency which is based upon important factors. The set of persons involved with the planning are therefore supposed to be adequately experienced, updated and well versed with the latest technology of signalling systems.
