While skinning over the 3rd rail site I now see that the remaining 3 rail N&W Y-6b's (Anniversary Edition, exceptional detail, has rail sounds 5 added to them. I think this is great news since rail sounds 5 has much more to offer than rail sounds 4. I have a couple of Lionel locos with rail sounds 5 and think it a vast improvement over 4 (UP H-7 and SP GS-2.
Hope to see rail sounds 5 added to ALL future 3rd rail releases.
What say you?
