how is it possible that a WAP-4 which weights in tonnes can be pushed so easily by people

This is because there is very less friction between the wheels of the locomotive and the train.
This is the fundamental principle based on which railways were developed. Steel wheels on steel rails experience far lesser friction than say, rubber wheels on a road (like trucks and cars). In fact the friction reduces by almost 85-95%, which makes it extremely easy to pull or push very heavy loads on rail tracks.
As an example, using very simple approximations and numbers, one can illustrate how easy it is to move things on rails.
