How the Hungary–Serbia Railway Demonstrates Compliance with EU TSI Railway Standards

When the Novi Sad-Subotica part opened in October 2025, the Hungary-Serbia Railway became a key cross-border rail route in Central Europe. More importantly, this project shows how a large railway can be built fully to EU TSI railway standards.

For the railway industry worldwide, this is not only about transport. It proves that EU TSI railway standards now decide what systems, equipment, and railway components are needed in international rail projects.

Where Engineering Meets EU TSI Railway Standards

The Hungarian part needed over 2,000 approval papers to meet EU TSI railway standards. These covered traction, bridges, tunnels, signaling, and speed tests.

During hot-weather tests at 160 km/h, engineers checked the pantograph and overhead line, voltage, and system reactions. This made sure the power supply follows EU TSI railway standards.

Such tests show what the railway needs, and how every part must perform.

What EU TSI Railway Standards Mean for Railway Components

Today’s cross-border lines need wheels, castings, axles, and parts made to EU TSI railway standards. The rules focus on working together safely, lasting long, and being reliable.

As trains carry more and run faster, parts must handle wear, heat, and stress while still meeting EU TSI railway standards.

That’s why material choice, casting quality, machining accuracy, and checks are so important for makers.

From Faster Travel to Higher Component Demands

After Serbia’s section opened, travel time between Belgrade and Subotica fell a lot. Freight efficiency rose by nearly 40%. When Hungary’s part runs, the route will improve logistics across Central Europe.

More freight and higher speeds mean stricter railway standards for the parts used every day. An old Chinese poem says, “True friends feel close even when separated by great distances.”(海内存知己，天涯若比邻)
This idea perfectly reflects the purpose of modern cross-border railways. By connecting cities, countries, and standards, projects like the Hungary–Serbia Railway make distant regions feel closer through shared infrastructure and interoperability.

A Signal for Future International Railway Projects

The Hungary-Serbia Railway is part of a trend: global rail projects must follow EU TSI railway standards to work across borders.

For part suppliers, this changes things. Products are now judged not just by strength or price, but by whether they pass tests and meet EU TSI railway standards.

Luoyang Fonyo Heavy Industries Co., Ltd. makes railway wheels and castings. We control every step—casting, machining, and inspection—so our products meet the tough railway standards for modern international projects.
