I have a Bachmann Big Haulers Royal Blue G Scale Complete Ready-to-run Train Set (details below) that I am struggling to get running.  Instructions were lost...  Im just just getting back into this after many years away.

Id greatly appreciate any troubleshooting tips, checklists to walk through or expertise from fellow train enthusiasts on this site. 

Thank you.

I have the same set but it always ran rough and jerky. 
I was about to sell it on Craigslist when I found this forum.
You can order a new Chassis for $40 or an Annie Chassis for $45 with metal drivers (looks better in my opinion).
Any of the 4 6 0 chassis will fit.  I ordered the 81097.  The new chassis run like a dream.

1. In terms of fixing your existing engine, First things to check is your power supply.  It should put out somewhere around 20 volts DC at full throttle. 
2. It could be that things are frozen up in your gear train which would mean opening it up and lubricating everything.  Also check to make sure there are no broken wires. 

There are a lot of posts on the forum about cleaning up Big Haulers.  Actually pretty easy to work on. 
A suggestion.   Grab some post it notes and scotch tape.  When you remove screws,  tape them to a post it and label where they came from. Makes it a lot easier going back together.   Near the top of the Large Discussion is a detailed description on repair tips.

Make certain your front truck has not been turned 180.  That will cause a short and prevent it from running. There should be a white arrow on the bottom of it that should point forward.

All track powered 10 wheelers have metal drivers. I think you are referring to the valve gear and side rods.
