I agree, not only 3A, the railways should attach some 2A coaches also to make it a proper and regular superfast express. The only question is whether the single existing platform at Haldia (HLZ) can accommodate that much long rake or not. Already this train is 15 coaches long. Any member from Haldia can clarify it. I have a doubt how the railways are doing the rake cleaning and maintenance also. There was no concept of "yard" there at Haldia, so far I have seen it 2 years back. There are many things to do, increase the platform length, make some pit/side lines, make proper arrangements for rake cleaning etc etc.
