Demonstrated that a single 4G LTE network can be used for all operational communications of a train, whereas today they are supported by different channels — a mixture of Wi-Fi, digital radio and 3G/4G networks.
RATP and Nokia successfully completed the first “real-world” trial of 4G LTE technology in a mass transit system.
Completed on a portion of the Paris Metro Line 14, this trial demonstrated that a single 4G LTE network can be used for all operational communications of a train, whereas today they are supported by different channels — a mixture of Wi-Fi, digital radio and 3G/4G networks.

The introduction of a 4G LTE-equipped shuttle on Line 14, an automated line meeting all RATP security requirements, is a world first.
The test showed that a single LTE mobile network can replace the traditional Wi-Fi networks and manage data transmissions from multiple applications simultaneously, including: a simulation of train control (CBTC simulation based on pre-recorded real data); video on trains and platforms; operational voice communications; multimedia passenger information on trains and platforms; and maintenance and supervision services.
This trial marks a significant contribution to start of the standardization process required before any operational rollout of 4G LTE technology in transport systems and associated customer services. It was completed under the R&D SYSTUF project, in which RATP and Nokia are collaborating.
The objective of this project is to demonstrate that it is possible to use a single telecommunication technology — such as LTE — that is able to meet both mission-critical and non-critical applications of future public transport systems.
As part of the experiment, RATP defined the applications that must be supported by the network and determined what constraints are to be met to complete a convincing, secure and non-disruptive trial.
The ATP board’s approval of the KAP team enables ATP to begin pre-construction activities, including advancing design, initiating permitting, and preparing the site for future construction.
The railroad has issued a formal request for proposals to manufacturers for more than 800 new passenger railcars that will serve 14 long-distance routes nationwide.
The delivery marks the first car in a 374‑vehicle order and begins the arrival of a new generation of higher‑capacity, more reliable, and more comfortable trains for one of the country’s busiest commuter rail systems.
BART recorded 5,403,140 exits in March, making it the highest monthly ridership since the pandemic and surpassing the previous high set in October 2025 (5,346,890 exits).
The station was rebuilt as part of SEPTA’s Station Accessibility Program, making it fully ADA accessible with new elevators, ramps, and high-level platforms.
The announcement highlights the long-standing partnership between the Class I railroad and the commuter rail system, dating back to Metra's creation in 1983.
Crews completed a significant portion of the testing required before commissioning the new, digital signaling system, which will bring important upgrades that strengthen Red Line service reliability for riders and provide Red Line Operations the ability to route trains more quickly, turn trains around faster, and recover from unplanned disruptions more efficiently, said MBTA officials.
