Thank you for the help.  In regard to the caboose, the one I was led to look at is an HO and my train is the original On30, so I think the caboose would be a larger than the rest of the train, but it is cute.
In regard to the light in one of my cars: I was able to open the top and I found the bulb to be broken. So now I want to be sure I order the correct bulb. Thanks

We have a Thomas Kinkaid Christmas Express which we started collection about 15 years ago. Wondering if there is a caboose.
Also, just replace both trucks on a passenger car, but light doesn't come on. Soldered the wires. Can the bulb be replaced? I imagine that is difficult if a bulb needs to be replaced.
Also, thanks for the information on the couplers and trucks. Ordered and they are all the right ones.

We have a Hawthorn Village collectable train. It is a Thomas Kinkaid, HO, Christmas Express which we began collecting about 15 years ago. We now are trying to make it all work like new and everything works great. I ordered all new couplers, but need a truck for one of the cars which was dropped and broken. I hope someone can help. This truck is fastened from inside the car with one screw. The wheels seem to be ok but I would take new ones, and if needed another truck to be sure both are the same.
