What also helps is if your PE team mate builds a BergeTiger and manages to salvage the Tiger wreck you can two of those magnificent beasts at your disposal on the battlefield.
I found this out when my son bult a BT and resurrected a dead tiger.
I was pretty fed up with the tank train at that point. The real struggle was actually holding all the ground I gained with that push, but it wasn't so bad because there weren't enough riflemen.
Didn't have the chance to watch all the replay yet, but around 22 minutes you can pause Hulk's POV with FoW on and count 10 M10s charging in, LOL. Cannot be a Bg when you win against that hell train.
I would also like to bring up an old image I made:
