<h1>Kalwakurthy-Macherla rail link: no firm timeline as DPR, stakeholder consultations and multiagency approvals are required before sanction.</h1> Rail infrastructure planning for the Kalwakurthy-Macherla link remains without a fixed timeline because project sanctioning awaits completion of a sanctioned survey and preparation of a detailed project report (DPR); the DPR must be followed by consultations with stakeholders and statutory appraisals and financial clearances. Project approval will depend on factors such as anticipated traffic projections and route remunerativeness, first and lastmile connectivity, and whether the link fills missing network connections; until these technical, financial and intergovernmental approvals are secured, no operative timetable can be determined.
