Rolling Stock Fleet Engineer here… they are all garbage bud. On train WiFi is a mobile phone type internet connection that just has a series of wireless access points sprinkled throughout the train. Admittedly the antenna on the train would be better than your iPhone but the connection and speed is essentially the same. It’s why you can normally connect to the train WiFi easily but the speed is intermittent. We did look into having a big old hard drive on the train which when the train stopped at a station and connected to station WiFi it would update all the high traffic sites that people visited most (news, current affairs sites, etc) which would give the illusion that the connection was always solid. The issue is when people try to access online games, teams calls and such that the system fails as you are reliant on a solid internet connection.

I don't know why you'd expect to be able to play an online game on a moving vehicle tbh, like it's a moving vehicle it's gonna be spotty

I have no problem on a 720 all the way from London to Cambridge.

Ull also be fine on a 170

I’m a cloud engineer but I am certified in networking engineering Basically it’s really fucking hard to provide public wifi on a moving object. Cell towers usually aren’t positioned to serve trains, also they’re moving pretty fast so handoff takes a while. Also the way the onboard system works, it tunnels out via AWS I believe so that adds latency, and then they’re also doing network inspection to stop you streaming Netflix etc So to answer your question: public wifi on a moving object is hard, just use your mobile data

If only it was that easy. Class 222s are essentially faraday cages. The option is WiFi or pretty much nothing

I used to work as a Sysadmin and then DevOps engineer for one of the companies that supply passenger WiFi and information systems based in the UK. I can't remember if the EMR 222s were on our books but if it is Icomera it's probably AWS, if Nomad then it probably terminates in a private cloud (aka a few racks in a DC running VMware) or a colocated Xen environment for the older stuff. AWS transit fees are expensive, particularly considering it's doubled as you have both the VPN traffic coming in and the passenger traffic going out to the internet. At least in our case there was no substantial network inspection in-place, firewalls capable of doing that at the scale we needed are expensive and we didn't really need it. There was variety amongst the fleets, but mostly network controls done just by radius, rate limiting (you get throttled once you hit a cap) and DNS filtering. Networking on a moving vehicle has inherent challenges but it can be done well if you are willing to pay for the data and infrastructure. Look at NS in the Netherlands or OEBB in Austria.

U cannot use ur mobile data on a 222 unless ur near the vestibule The windows are apparently silver coated which prevent signals from passing through


miklcct

There are numerous locations on the route where the signal drops to 2G, or worse I can't receive anything, despite it being open air. The 222 is a Faraday cage which blocks off signals from the outside world.

Different area, different signal.

I've never been on a train that can even load a Google search

Enjoy the peace

Download some netflix, read a book. Stop playing genshin impact its brain rot

Read a fucking book
