How does the Wi-Fi work on trains?

How does onboard wifi work? Most train wifi ultimately depends on the broader mobile communications network. The train's antennae pick up the signal – usually 3G or 4G – from regular masts or base stations near the tracks and connects passengers via routers in carriages.

As the train zips along, its routers must keep up by hopping from tower to tower. A gap between sites can interrupt service. On stretches with underdeveloped infrastructure, such as rural areas, passengers will find themselves time-traveling to a pre-internet era.

Highest values of rail vehicle aerodynamic loads can be reached along the entrance and passage through a tunnel. When a train passes through a tunnel, pressure waves are generated which propagate along the tunnel approximately at sonic speed.

“So there's a lot of pressure on that tower from the people on the railway and from the outside world. This could result in slow internet or even dropped connections.” Natural and man-made features, such as mountains, tunnels and skyscrapers, can also impede the connection.

Reduced traffic: During the nighttime, there is generally less road traffic and fewer other trains on the tracks. This allows trains to move more efficiently and with fewer delays, as they encounter fewer obstacles and can maintain a consistent speed.

In the U.S., the data speed numbers on the “Eastern Corridor” rail routes show that T-Mobile has the best results (compared to other operators), but 5G coverage is very patchy, and the example of train #449 shows that about half of the route simply has no connection.

MORE DETAILS

Trains go slow at night to ensure safety due to reduced visibility, and to navigate through potentially hazardous areas. Trains do slow down at crossings to reduce the risk of accidents and to sound their horns to alert people.

Some trains may have composting toilet tanks, which use bacterial action to break down solid and liquid waste. Only the broken down clean liquid is released to the trackbed after sterilisation. The solid waste only has to be emptied every half year.

Its primary purpose is to alert persons and animals to an oncoming train, especially when approaching a level crossing. They are often extremely loud, allowing them to be heard from great distances. They are also used for acknowledging signals given by railroad employees, such as during switching operations.
