Great photo M.J. Breen!   So 611 is fired up during the move.  

Absolutely.

I was thinking that the 611 was going to be pulled dead in tow.  

A steam locomotive can not be towed dead, unless the main rods are removed, which then limits the towing speed because the running Gera would be out of balance. The lubrication for the valves and pistons is carried by way of the steam, i.e. water soluble valve oil, thus it is much easier to simply fire up the steam locomotive, and work a little bit of throttle so that the valves and pistons are always lubricated during movement.
