Metal Siderods and Valve Gear?

[keeping track]

I had the idea that only Annies have metal siderods and valve gear, but I read on some site that the more recent Generation 5 Big Haulers do too.  Is this correct?  And specifically, does the engine in the Big Hauler Set Pennsylvanian #90082 have metal or plastic siderods and valve gear?

I appreciate the help.

Hi,

Only Annies have metal siderods.  The Pennsylvanian set has plastic siderods, but is a version 5 chassis.

What site were you looking at??
