Despite the obvious importance of timetables in appraisal, we have failed to find any mentioning in appraisal guidelines of how analysts should construct timetables. For example, the extensive guideline RAILPAG(Railway Project Appraisal Guidelines), intended to be “a common framework for the appraisal of railway projects across the EU”, does not mention how appraisal timetables should be designed ,what stakeholder should have the responsibility for it, or how appraisal results might be affected by it. Neither of the national appraisal guidelines of Sweden, Norway, UK or the Netherlands mentions the topic, despite having detailed formal appraisal guidelines covering virtually all other parameters and dimensions.
