Welcome to the website that describes the
ABSOLUTELY BETTER JOINT
an innovative device that improves SAFETY of the railway track

SAFETY FIRST!

Railway tracks are plagued since ever by broken joints.

A real alternative is available. Now.

A strong cooperation

The developers

The manufacturers

AB Consulting is the consulting company that prof. Bracciali funded in 1994. The idea of the ABJ came to prof. Bracciali in August 2021 and since then the joint was (and still is) continuosly improved and developed.

The patent application was filed in 2022 and the patent was granted in 2024. A license agreement was signed with Overail srl to sell the ABJ worldwide.

Overail srl is the company belonging to SALCEF group that makes use of extensive automation to manufacture more than 4500 concrete sleepers per day. With impressive competences in manufacturing, Overail is best partner to reliably produce large quantities of ABJ with top quality and reliability.

The sponsors

Listed at Milan Stock Exchange and more than 1500 employees, the SALCEF group is one of the world leaders in civil engineering related to railway infrastructure in electrical, civil and railway engineering.

In this website we'll guide you to the discovery of what we called the Absolutely Better Joint (ABJ), a new type of insulated rail joint (IRJ). IRJ are needed when track circuits are used for signalling.

first presented at the CM2022 Contact Mechanics conference in Melbourne, Australia, on 5 September 2022
put on display at InnoTrans in Berlin (20-23 September 2022)
discussed during a webinar at The Permanent Way Institution on 25 October 2022
described in the paper published on the authoritative scientific international Journal "Wear" in July 2023
tested at TUM (Technische Universität München) from April to Septmber 2024
put on display at Innotrans 2024 at SALCEF / OVERAIL stand (hall 26/240)

ABJ arises from a thorough study of mechanical behaviour and failures of IRJ in service, introducing a number of features that potentially solve all the problems of existing IRJ, dramatically improving reliability and SAFETY.The joint wasEnjoy the navigation!
