A set of (4) different CDs that present a variety of AUTHENTIC TRAIN SOUNDS. Perfect for hobbyists, collectors and those who just like the sound of trains. All of the CDs were released between 1994 and 2003 by Big Train Sound. (The CDs come with a funny caution warning that warns that the recordings have such realistic sound that they may frighten some people.) Please check out the photos for all the details as to what is included on the CDs. All of the cases and inserts are shown. All of the CDs are brand NEW, still SEALED in the original wrap. You will receive the sealed CDs shown in the first two photos. The remaining photos are of opened copies. Please check out the photos as they are considered part of the description. NICE! Shipping is free by Media Mail in the USA. No international shipping. Please check out my other listings for more fun stuff. Thanks for looking!
