Query: Great educational value with real train footage

My son just turned two and this is now his favorite video/dvd. It is approximately one hour of real train footage. The narrator and captions follow the alphabet to explain many aspects of train travel and general information about trains. The video is neither annoying (a relief after too many Thomas the Tank Engine videos) nor exciting. Yet, my son is riveted by the footage. He also shouts out the alphabet letters with the narrator.I highly recommend this video to anyone with kids 18 months to 5 years. Especially if your children like the actual footage rather than animation. Also check out the Real Wheels series and Straight Up (and Imax movie on helicopters).
