bkil [tantek]: We still have a single ~3.6Mb/s 3G modem shared over wifi per carriage on most of our trains. It was top notch when deployed around 2013, but it's not considered very good today and 3G switch-off is also imminent. They started rolling out updates to 4G in 2021-2022 on premium class, but I don't think they are quite finished everywhere.
