I run the turnpike 4 days a week from Pa. to Chicago and I have heard this a few times myself. Dispatch always tell everyone that it is going to happen and for how long it will be run that way. Maybe this happens for upgrades to the system and or software.
This was pretty common during the installation and switchover to MARCS, nothing too out of the ordinary.
I am impressed how they pull it off relatively seamlessly, but OTP dispatch has always been remote, so of all the districts this may be the easiest to have Columbus pick up the radio and CAD temporarily.
