Ghost train running again in my dark loft

Ghost train has a B unit which is motorized using power functions. And then it is pulling an observation car and a coach. There are some other train MODs and MOCs in the attic too, but it was too cold to spend any longer up there to get anything else running. I didn't run any of the Santa Fe trains seen in the background in the clip because they don't like the sharp standard Lego curves, so I am thinking of getting some after market bigger radii 9V curves and using 9V motors again with them...
