For those of you who are as old as I am and remember the Buddliner RDC's, I just found a very nice rendition of this Rail Car over at
www.trains-and-drivers.net Just as I remember them with the exception of the horn, which I have swapped out for a closer sounding unit from the F40PH. Engine sound is very close to the original as I remember it.There are four configurations you can choose from. I consider it a good buy at $16.18 USD.
