The model is in excellent working order. Runs smoothly in both directions and all sound functions work. Sounds great! Function list can be found on Bachmann's website. The cosmetic condition is good. There is a buffer missing. I belive that the buffers are found across several models and therefore you can use the silver class 20 buffers as a replacement. These are readily available and not too expensive. Rest of the model is flawless and would make a fantastic addition to your layout.
