Best rail networks for fast and reliable mobile data

[johncrossley]

What are the best rail networks for fast and reliable mobile data? In Switzerland I found coverage very comprehensive, even in tunnels. I saw someone participating in an online meeting on the train. The Netherlands seems very good as well, although the terrain is very favourable there.

In my experience, Switzerland is the best, I haven't had any moments without good connection, even on remote mountain stretches. France and Spain were pretty good as well on the high speed lines. I could do online meetings without big problems, sometimes a bit of a delay, but nothing like Germany. Over there, coverage is really patchy and I've had a lot of difficulty to just check my mail. The Netherlands are pretty good I would say but as someone who lives there, I travel quite a lot and know some places with bad coverage but generally good.

The Netherlands used to be very poor with coverage in tunnels, this was only recently improved. Now only a few spots with poor coverage remain, mostly on lines trough large foresty areas.
Agree with biko that Switzerland is by far the best.

France away from the main lines is also very, very patchy.

In the Netherlands, Schiphol tunnel/station still remains as a more significant spot without coverage (well the bars show up, but nothing actually works).

Before I discovered that mobile data works in tunnels in Switzerland, I didn't even realise that was a thing.

Switzerland is the king, I had full 4G+ in the tunnel at the top of the Gotthard Pass

France has very good coverage on LGVs but some rural lines are very patchy indeed though that should be remediated soon as it is in law that all lines that aren't LGV have mobile coverage by 2027

The network in the Schiphol tunnel has capacity issues due to ageing equipment. That's why bars show up but there is no actual connection.
Should be upgraded this year as it has to be combined with maintenance by ProRail.
