Gatiman Express (Nizamuddin / Agra Cant) is being hauled by Ghaziabad WAP5 locomotive. Why WAP7 which is more powerful is not used here?

One reason is the space constraints due to the new transformer, as mentioned in the other blogs. This was a problem at that time, because, even though transformer taps were provided, a converter still had to be installed in the locomotive to be able to connect to the transformer and supply the power to the rakes. Usually, the transformer tap+ converter combo is decided based on the maximum rake length ( i.e., maximum power drawn by the rake) that the loco has to handle. Since the passenger trains in India are usually much longer than their European counterparts, the original design was not sufficient to power the longer Indian rakes, and an upgrade was required. This was easy in the WAP7 as it was a longer loco than the WAP5 and had enough space.
