I know Harris is trying to reactivate the NS trackage, and I think he intends to run airport-ND shuttles - over on the MARC forum they are discussing how MDOT is trying to unload some RDC's to a charitable concern - might this be easier than stringing wire and running 1500vdc MU's on his route, at least initially? Check the RDC thread on the MARC forum for background, specifically the last few posts.
