First of all Fred that was a fantastic response, thanks for that.

 Now HI DB,   

Your set was made in 1996 and is about 30 years old now.  The locos are chassis version three, which had gear problems.  Freds recommendation to get Chassis version 5 or above is spot on.

There are decal makers that could reproduce the lettering and numbers, but it might be expensive.  Bachmann made an add on coach and a full baggage.  If you found more coachs on ebay they will all have the same number.

I really don't know of other Bachmann locos that match the Southern Railway paint on yours.  Some of the specialty paint makers might have some that match. 

AS for the broken front truck on one of your locos Bachmannn makes a replacement that will will work, but your description of the damage is pretty severe.  I would recommend junking it for parts for other locos, especially if is not a version 5.

Best I can do for now, have fun with your trains!

I see you have been really progressing very well!  Great going. Keep having fun.

HI Battleflail,

Your best bet is to do two "saved searches" on EBAY with email notification. 
Set it up under the G Scale section of EBAY  Do one on the "set number 90036", then another on "Polar Express"
Probably many of these sets are sitting in attics with the Christmas decoration boxes, but you never know when one will come up.  Bachmann never made  a full baggage or a combine in Polar Express livery.  If a set does come up I would suggest buying it even though you will get a second locomotive and an extra observation car. Then you would have a four car consist with two coaches and two .observation cars. Who knows you may get lucky and find someone who breaks up a set and sells the pieces separately. 

Enjoy your set, and good luck finding more cars.

Extra Info
I have written book with all the Bachmann set in it but which no publisher was willing to publish.  Anyway I have posted the part of the book covering the Polar Express set for those who may have an interest. I did not include the pictures and the EBay sales info is mostly out of date.

No matching Polar Express full baggage or combines were made to go with this set.

Introduced in 2000, The Polar Express was based on the classic children's book of the same name.  By the time the movie came out Bachmann was no longer licensed to use the Polar Express name, or box graphics.  As a result the set being out of production, became highly prized, bringing very high prices on Ebay.  A year after the movie was released, prices on Ebay were back down to about $275.00 to $300.00.  I do feel that the green and maroon passenger car colors are very classy.  If one considers Bachmann sets collectible, this would be a must have set.  This set was in the catalog from 2000 to 2002.  The locomotive in the set does have the latest smooth running version 5 chassis.  It is doubtful that this set will ever be introduced again.  None of the pieces in this set were ever available separately.  The original MSRP was $380.00 and the discount mail order hobby shop price was $175.00.  The set still shows up on Ebay usually around Christmas time, but is rarely offered.  The price range on Ebay is from $200.00 to $700.00 and the average price is about $300.00.  Since I have so few sales records of this seldom offered set, the prices noted should be considered accordingly.

End of Book info.

Yes Bachmann still makes track. You may have sticker shock on track prices as well. Give Robbie at RLD hobbies and he ca give you the prices.
Bill

The $99 for the EOT is the Bachmann the suggested MSRP. the street price will be much lower.
I am sure you can get a much lower price the EOT at discount mail order hobby stores like RLD hobbies.

Thanks Bach-man,

I stand corrected,  Glad you are feeling better and have helped resolve the question. 

All the best, Bill

Hi Mickey,

My Climax is in deep storage and I did add the slip driveshaft to it, but I don't remember if it was the front or rear. I did see this in the parts list:

https://estore.bachmanntrains.com/index.php?main_page=product_info&cPath=69_641&products_id=8300

I can't remember if the above is the one with a slip joint or not.  Just thought I would show it to you. 

Bill

Hi Doug,  I dont have one but looking at the close up they appear to me to be molded.

Loco Bill

Thanks guys!  Bill

Hi Daniel  This will work as a complete replacement it is the improved version, and you would have to drill one hole to attach it.  https://estore.bachmanntrains.com/index.php?main_page=product_info&cPath=69_671_148&products_id=8545

Greg,

Correct outdoors, but when did it start raining indoors

Bill

Make sure your pine boards are moisture free, if they are not they will shrink. Also never have a track joint directly over wood joint. A friend used small dabs of the cheapest caulk every 5 feet and never seemed to have a problem. He also put the boards in the house so they would adapt to the interior temperature before construction. 

Have fun, Loco Bill
