World class railway station projects are primarily envisaged through private investment and Government funds are required only for preparatory works such as consultancies for feasibility reports and advisory services, for which funds are allocated from time to time, as per requirement.
Work at site shall commence after award of concession to the concessionaire and financial closure by the concessionaire. After award of concession, completion of project is likely to take 5 to 6 years due to complexity of work and necessity to undertake the work while keeping the station operational.
This information was given by the Minister of State for Railways Shri Bharatsinh Solanki in a written reply to a question in Rajya Sabha today.
