Michael,
I'm not sure I can word this to not sound mean spirited, but have you all thought about a 3 way trade that somehow might get someone a nice tax write off, and get your operation an engine you can realistically use? Seems like she's a nice display for you all, but Rachel was such a nice fit for DRG. Small and economical, and at DRG, under state boiler laws, not FRA, as may come into play with a semi-suburban commuter type use, as I have seen suggested.
While it was a nice donation, the support structure needed, ROW-track-cars, would cost far more in excess than the asset. Building a whole new operation around an engine? I am I just missing the point?
All that aside - I think Grapevine has a fine RR and wish you all continued success.
