As per adv about change of schedule due to closure of of Dhanbad Chandrapura on Times of India, Kolkata, ER twitter page in June 2017, the schedule of 12020 of DGR and HWH after (15.6.17) closure and on 28.4.18 when I’m writing are same. In the adv Khana pass was 19:50 after closure – so, it maybe same on 28.4.18 when I’m writing.
