Could someone describe the differences, if any, between the sounds of Lionel Vision Lines freight cars and Lionel FreightSounds cars? I have several Vision Line freight cars and they are great. I had the original FreightSounds cars and returned them all because they were primarily banging with little flange squeal. I have heard the new FreightSounds cars have been improved but I don't want to buy any until they feature primarily flange squeal. I assume the Vision Lines cars have more features because they are more expensive.
Thanks,
Al
