I nees help on information on this video called Trains along the Mississippi. My local ibrary had it and now it is gone. and NO IT IS NOT Trains along the upper Mississippi by Pentrex it is just simply called Trains Along the Mississippi covering the Burlington Northern and the Soo Line and Amtrak's Empire builder from the Twin Cities to La Crosse WI. I think it was made around 1993. Not sure thoug any info on where I could find it?
