Thank you everybody for your answers and knowledge.
I appreciate it.
Jonathan I think I might try the super glue thing to see if it works.

Also I was wondering if any HO scale train would fit or work on that track or does it have to be a 0-6-0 locomotive?

Thank you for your answers. I appreciate them.
The set that I am talking about is similar to the one in this link.
https://www.ebay.com/itm/BACHMANN-WHITE-CHRISTMAS-EXPRESS-model-train-set-00609-HO-SCALE-EUC/401438502949?epid=2255409849&hash=item5d77997025:g:y78AAOSwR2RaA1uH

I am going to see if I can get the part picture loaded. I borrowed the picture from
http://estore.bachmanntrains.com/index.php?main_page=product_info&cPath=66_68_155&products_id=1565

The two white pieces on the ends are broken, they have cracks that run the length of them. Not the middle gear. So every time it runs it pops loose and the wheels come out of the white thing holding it together.

I need some help.
I am really new to the train scene.
My in-laws a couple of years ago gave us a Bachmann Train Set for our kids.
It happened to be the BACHMANN WHITE CHRISTMAS EXPRESS model train set (#00609) HO SCALE.
It has ran the past couple of years.
Then this year I have gotten it out and it will barely move or run.
I took the base off of it to see if there was anything in it and noticed that the two white axles were broken. They had cracks in them.
So we packed it back up and don't know what to do now.
Is there any advice you can give me?
Do all HO scale trains work with this track or just Bachmann?
I have noticed that trains can be very pricey brand new and I don't know enough about them to look for them on ebay.
Just kinda trying to figure things out.
Any help would be great.
Thanks for your time!
