LOL....toh tumne SER zone mein toh gitanjali and mumbai mail ka naam daal rakha hai....
Aur sabse badi baat....Jis basis pe tum Gitanjali ko SER ki train bol rahe ho, on same base we can also add Purushottam exp for ECoR.
Gitanjali ka actual present rake ECoR ka hai. The rake is NOT of SER. Then what basis you have added Gitanjali in SER zone ?
And...
more... Similarly, SECR zone ke liye tumne 4-5 trains ke naam add kar diya hain....On what Basis ??? SECR was formed on 2003, so as per your logic, ONLY BSP bishrampur exp should be present. Why you have added chhattisgarh exp , narmada exp etc ?? When these trains ran, they were of unified SER zone.
Its your blog, so your decision to decide the criteria but i just wish inform you that if you are making any Zone Wise Oldest train, then You CAN NOT consider the zone allocation to the respective train at time of inaugration. You HAVE to consider the PRESENT zone allocation like Chennai Mail while at start was under SR, but you have to tag it under SER only. Same is with Kalka Mail. While at the start it was under GIBR , So that doesnt means you will tag kalka mail under GIBR. You have to tag it under ER only.
Similarly at the start Purushottam exp was under SER, but you CAN NOT tag it under SER. You have to tag it under ECoR only.
