I just picked this Lionel Pennsylvania Rail Road RS -11 today. It wasn't a planned purchase but the detail was just something I never saw in a scale diesel at this price. So I bought it and I couldn't be more happy. This is my first Lionel modern diesel and I am very surprised at how it compares to MTH Premier. The first think I noticed was the rollers. They are built much stronger and beefer than the MTH rollers. The smoke unit works as well if not better with the fan driven unit. Just the weight and feel of the engine is so much better. While this is a scale model it is not one of their TMCC units and for $225 I was very happy. This engine brings back the glory days of the older Lionels. The pulling power can be compared to the modern Williams engines that are being made. However as I stated the detail is just great. Well enough talk here is the new Lionel RS-11.
