What is up with the roof line on that cabbage? Never seen one like that before.
they are transmitting live from the train (claim it is first time ever) and those are the antenna for the transmissions (I would suspect via microwave but ??)

It looks very similar to the systems we have on all of our Navy ships... two antennas that could be on the same bird, or on different ones for redundancy. The satellite dishes are mounted onto a mount that can move quickly in both azimuth and elevation. The mounts are controlled by a computer that is connected to a GPS reciever and a gyroscope that tells it the location of the train, as well as heading and any yaw, cant, and elevation. This allows the computer to keep the dishes locked on to the bird using the motorized mounts even as the ship rocks and rolls. It's pretty amazing to watch them work inside those domes, as they are rock steady pointed at the location of the satellite, whereas the ship could be rolling like crazy.
As for the band, it could be C Band (4 to 8 GHz), but the size of the domes looks like it could be more like Ku (11 to 12.7 GHz), which is better for punching through rain and fog, and uses smaller dishes than C Band. DirecTV and Dish Network use the upper section of the Ku Band, for example. Both bands are considered "microwave", however.
