Moving a Doble with Compressed Air

@Chris today I helped a friend move a large heavy Stanley.  This car has an air hose fitting on the boiler.  It allowed us to attach a hose from a compressor and with around 100 plus lbs we were able to move the car without firing it up.   I told Perry about it and he wondered if there was a place in the Doble to add hose connection and accomplish the same thing for moving the car short distances.

Compressed air cars might deserve their own topic somewhere.
