Just curious if anyone is swapping out some of the plastic wheels and axles on Big Hauler cars.  I have a few cars that are prone to derail and I think it is because of the wheels on the cars, maybe not being true or possibly binding.  If you lubricate those wheels,  what do you use?   No problem with the engines as they all have had the chassis replaced last year. 

Tried to post a picture of my Big Hauler conversion to a Polar Express but I keep getting a message that the upload folder is full.  My picture was only 94 KB.

All of my engines that I am converting to Annie Chassis are Version 2.   They only have 1 smoke Switch behind the front plate and only 1 pin connector for the Chuff sound to the Tender.  The Annie Chassis have a second pin connector.  What is this second connector for?
I don't plan on using the smoke box so will leave that switch off but I do need to connect power to the leads that connect to the smoke box switch and also the headlight.  Where is the easiest connection for these? Is there a chance there is a wiring diagram somewhere for the Annie Chassis?

I am retrofitting 3 new Annie Chassis on 3 older Big Haulers.
In reading the instructions from Loco Bill there was no mention of the large weights that sit over the motor gear assy inside the old engines. 
It looks like these can be moved to the new chassis but unsure if this is recommended. 

I want to convert one of my 4 6 0 Big Haulers to a Polar Express for my Grandkids.
I am unsure what kind of decals to get as I see there are vinyl ones and others.
I would appreciate any comments on how any of you have renamed and customized your engines or rolling stock.
Thanks
Doyle
