Yes, wall level durability higher than his street level one. Especially when in base he tanked a long fall onto several big branches.
They are still his own powers, as the parasite did not increase them, only control them to his will. I would agree putting in a key/varies/"via size manipulation" tier

One interpretation, given her inclination to force and established extra-normal strength, is that she would have physically destroyed it, destroying game machines has been put at wall level on other pages.
If she matched the suit's physical force which tore up the floor, and damaged the suit which can withstand its own strength without breaking, why would she not scale at least with the pipe?
I don't know about using the train, it's not exactly a weapon, and it might lead to wonky tiering depending on how controlling infinite train cars with each supposedly its own universe is interpreted...
