Meyblc what are you talking about? The 4266 does run under its own power. On June 5th of this year, me and my girlfriend rode the Conway Scenic and the 4266 was the engine they were using for that day. The FB9's were on the other side of the Notch picking up the 573 and the 3 other engines the Conway Scenic acquired. Yes the 4266 needs an overhaul, which the Conway Scenic and its owner the 470 Railroad Club are aware of. From the sounds of it both the Conway Scenic and the 470 Railroad Club are working on a time for when this will happen. One of the employee said it will not happen until after the two FB9's are repainted (scheduled for this winter coming up). This is also one of the reasons the Conway Scenic acquired 2 more engines because currently the 4266 is the only back up engine.
I do have picture from that day, that I will be posting on NErail, but haven't had the time to do it yet.
It takes real skill to choke on air, fall up the stairs and trip over nothing. I have those skills.
