As per VB maintainance schedule it requires complete inspection after 18 months for 15 days. So at present there is no necessity to station an extra rake at any stations. One rake should be given to New Delhi from Jan 2024 when CDG Himachal VB completes 14-15 months and stationed there as spare. Another spare should be kept ready at Chennai ICF and as and when some rake goes to ICF then it can be used as replacement.
