Not fair to author! I tried to run three Horshoe Curve Scenarios posted here, but they failed to load. Something about "could not find the engine" (Sharknose, which runs under "Career") and a rebuilt consist error message. But here's the unfair thing: When I choose "EXIT," I am compelled to "rate the scenacrio." This is an aplogy for the "Thumbs Down" I chose. I hope you understand. The run you posted is great ... to read other comments. jvia Wheeling Creek WV
