Yes a much needed train from Howrah to Yeswantpur on Thursday departure HWH as on Thursday there is no YPR Duronto and No Ypr Humsafar. This Thursday departure was a long pending demand and SER finally slot is available and this train must be made to run as regular train.
All the additional special trains that SER is currently started in last few days towards LTT, Pune, Ahmedabad from Santragachi/ Howrah is the requirements of passengers and i think these special trains would have been Introduced as New Trains before West Bengal Elections with AC Coaches also in CC if some political factors would not have impact on it also COVID is a factor.
But...
more... still hope in future these special trains are made regular.
