As I can see in this site, that there are 3 rakes for this train, the one going early morning from tata to bmpr and returning back by 10:45, is resting throughout the day at TATA, the other one thet leaves tata around 6 returns back around 2:30 and goes towards Gua and returns back at night. Correct me if I am wrong, the one that returned early can also go towards Gua, as it has more resting time. The third rake then lies completely unused. That means some more locals can be introduced using these rakes easily, like CKP/ROU etc. As the CKP-TATA spl. is now cancelled, inspite of huge demand!!
