Early today I caught this train on a DPU notice the antenna. I have gone through all of my GEVO pics BNSF UP CSX and NS and this is the first time I've seen this. Does it have anything to do with PTC.

Could be Wifi of some sort. I have heard the Class 1's do downloads on the move in terminal areas through some sort of Wifi system. May not be actual wifi, but something similar requiring an external antenna.

UP uses 900Mhz for wireless automatic downloads.
