12553 SHC-NDLS Vaishali Express standing at Siwan Jn.
Regarding maintenance,CDO Maintenance was decent..Passengers made it dustbin enroute, specially the toilets..I hate Bio Toilets..Always there is an idiot to make it choke by dumping something in it.
Run in NER was excellent..The train arrived many stations early..Run in ECR was average and poor in NCR.
