I picked up 2 Lionmaster Challengers yesterday. Western Maryland and Rio Grande. They look great and really look nice on 072 curves. Here are some pics and also a link to a quick video. The sounds are great, almost a Big Boy type whistle. You can see in the pics and video how it compares to my scale NKP Berkshire in size. You really cannot notice any difference and scale rolling stock looks fine begin these. The Big Boy is so ugly on 072 curves I got rid of mine. At 869.00 these are great for a Legacy Engine and all the features.
As a side note, the WM one has a smoke unit issue. It works fine when moving, but at standstill the fan shuts off. So it goes back tomorrow for a new one.
They do not have cab lights in them for whatever reason.
I heard Pre-Orders were vey low so not sure if we will see these again. Its too bad because these are great models.
Here is a link to the video.
