Acha OK, my mistake then!
I thought that this one was an ECR rake and was extended to GAYA because anyhow it used to come to GAYA from SSM for maintainence purposes!
Secondary maintainence is possible is 4 hours though the train wouldn't be able to visit the DHN yard !
One thing that baffles me is that 'GR' that runs on fully...
more... A category (140 certified) railway tracks has a 110 MPS limit.
It should be upgraded to 130 kmph too!
