I agree it is using LHB rakes. But I think it is using the used LHB rakes of MYS Shatabdi. The livery of CBE Shatabdi is same as MYS one. But, I think 12007/8 has got a new LHB rake and the old rake was transferred to CBE Shatabdi.
Also with reference to Blog Entry#: 1264918-0, the name board proves that this rake was earlier used by MYS Shatabdi.
