I’ve got a Bachmann 2 truck Shay that apparently needs new batteries. I ran it today, after a full charge, and got all of 15 minutes of run time.
I did NOT do the install on this one, so I don’t have any idea of how to take it apart.
Anyone have directions? 
If the oil/coal/water bunker is like the Climax, gently pry out the two hand valves on the top, and the screws are under those valves.
Step 1 pick up phone
Step 2 dial 1+425-823-3507
Step 3 ask Dave 
John I believe you are correct, I’ve had mine open before but can’t remember what I did to get to that point!
Screw inside water fill-remove
Old Truck-Plastic Ladder…lift/remove ladder
New Truck-Metal Ladder…leave ladder in place
pry up from rear-2 tabs in front near cab press back-lift out
I think that is what he told me…or something close to that
He has L-Shaped batteries on hand
somehow we always forget George???
Ship it to me I’ll take it apart put it in a box and send it back to you … NO CHARGE!
Thinking Bruce would like to be able to run it again tho.
Call Goodson, he’ll talk you through it.
Got it. Pretty straight forward.
