In May 2014, the French weekly newspaper Le Canard Enchaîné revealed that hundreds of new regional trains ordered to modernize the French rail system were too wide to operate safely on parts of the existing platform network. These trains, known as TER (Transport Express Régional), were ordered in two models: 182 Regiolis from Alstom and 159 Regio 2N from Bombardier, which were built in Crespin in northern France. The new trains were designed to be wider to meet public demand for more spacious and comfortable travel. However, this change required the modernization of 1,300 of the 8,700 platforms across the French rail network, according to the national rail operator SNCF and the infrastructure manager Réseau Ferré de France (RFF). The issue stemmed from the division of the French railway system into two separate entities since 1997: SNCF, which operates the trains and places orders with manufacturers, and RFF, which owns and manages the tracks and platforms. SNCF provided specifications to manufacturers after consulting RFF, which was responsible for providing data on platform widths. However, RFF later admitted that its data was incomplete and outdated, leading to incorrect assumptions about platform dimensions. SNCF proceeded with the orders based on these flawed numbers, without verifying them through a detailed station-by-station review. The French rail network is not uniform but has evolved over more than 150 years, with each section built under different conditions and safety standards. Designing a single train model to fit all these varied platforms without a comprehensive check was likened to making a standard-sized garment for a group of people with vastly different body types. Despite this, 300 of the affected platforms had already been modified by the time the issue became public, showing that the technical teams had recognized the problem earlier than the media controversy suggested. RFF spokesperson Christophe Piednoël explained that the necessary adjustments to the platforms could be as simple as trimming a platform by a few centimeters or repositioning an electrical cabinet that was too close to the edge. SNCF had to initiate a multi-year project, from the end of 2013 to the end of 2016, to complete the modifications in time for the new trains to arrive. The cost of these changes, estimated at 50 million euros, was covered by RFF’s annual budget of 4 billion euros for network modernization. However, the regional governments refused to contribute to the costs, with Alain Rousset, then president of the Association of French Regions, stating that local authorities should not be held responsible for a design error that was not their fault. The then Minister of Transport, Frédéric Cuvillier, described the situation as “comically dramatic.” The controversy coincided with a major railway reform being debated in the National Assembly in June 2014, which aimed to merge RFF and SNCF into a single entity. Critics used the platform issue to question how two public organizations could fail to share basic data like platform widths. This led to the creation of SNCF Réseau, which inherited RFF’s responsibilities and aimed to improve communication between the operator and infrastructure manager. RFF’s former president, Jacques Rapoport, emphasized that the need for wider trains was driven by the desire to improve speed, comfort, and accessibility for people with reduced mobility. He argued that the issue of platform width had been identified in advance and was already being addressed. A government response to a parliamentary question further suggested that the platform issue had not been a sudden discovery but rather a problem that had been known for months, only becoming public through media coverage.
