Sir, just check the PR in 2007/08. I am also trying to check the PR of SCR, and will post ASAP. First Triweekly, next 4 days a week with an RSA with YPR Garib and then it was daily.
One can check the EOG of today's 12739 ex.VSKP with ECoR markings, repainted as SC and coach number is 0885X
GR was inaugurated on 23-10-2008 as a tri-weekly and four-days a week from Dec 2008, I guess...
