For this reason when an engine has to pull a really heavy load, such as Australian iron ore trains, multiple engines are used, up to six or maybe even more, and if that is not enough, maybe a couple at the end to push as well.
You can hear the engine suddenly speed up, as it suddenly blasts out a huge amount of smoke as its powered wheels lose traction.

I reverted to the old Blogger interface and all is well.
