TGV driver killed in collision with military convoy at Bully-les-Mines

Lire en français : Collision TGV – convoi militaire à Bully-les-Mines : le conducteur tué

The driver of TGV 7304 from Dunkerque to Paris-Nord was killed shortly before 07:00 on Tuesday 7 April 2026 when his train struck an oversized road convoy carrying French Army bridging equipment at level crossing No 96, between Mazingarbe and Bully-les-Mines in the Pas-de-Calais. The train was running at around 160 km/h. Sixteen people were injured, two of them seriously, out of just over 240 passengers on board. France's land transport accident investigation bureau, BEA-TT, opened a technical inquiry the same day.

A 70-tonne load stranded across the tracks

The lorry was driven by a civilian employed by a private haulier and escorted by a pilot vehicle. It was carrying a military mobile bridge on a trailer, with a total weight of roughly 70 tonnes. According to regional press reports, the convoy was returning to Angers from an exercise in Belgium. It was on the rue Lamartine road crossing, across the tracks, when the TGV arrived.

The leading power car derailed in the impact and the trainset only came to a stand several hundred metres further on, according to the Prefect of Pas-de-Calais, François-Xavier Lauch. Windows in the first passenger coach cracked but held. The two seriously injured were flown to Lille by helicopter; more than 80 firefighters attended and SNCF laid on six coaches to move passengers.

Transport minister Philippe Tabarot and SNCF chief executive Jean Castex visited the site that morning. Castex said the crossing barriers had worked correctly, and a TER regional train had passed over the crossing without incident shortly before.

A four-barrier crossing outside the national safety programme

PN 96 is an automatic crossing with flashing lights and four half-barriers (SAL4), which close the full carriageway in both directions. It was not among the crossings listed in France's national level crossing safety programme, which targets sites with a record of repeated accidents or heavy road and rail traffic (155 crossings at the end of 2018, out of more than 15,000 nationwide).

That points the inquiry towards the interface between abnormal-load movements and the railway rather than towards an equipment fault. National guidance says routes without level crossings should be preferred for heavy or slow convoys, and that hauliers should contact SNCF in advance where a crossing may be difficult to clear.

The signalling view: what the system does not cover

On a conventional line a TGV runs under lineside signalling and KVB speed supervision, like any other train. Level crossing warning is triggered by the approaching train and protects road users by closing the road; it does not check that the crossing is clear. As a rule, French level crossings are not fitted with obstacle detection linked to railway signalling.

At 160 km/h a train covers about 44 metres per second, and its emergency braking distance is well over a kilometre. A vehicle trapped between the barriers when the warning starts therefore leaves the driver no margin at all. This is why route planning and crossing procedures for abnormal loads matter so much: they sit entirely outside the signalling system.

Criminal proceedings and technical investigation

The lorry driver, a 30-year-old Polish national living in France, was taken into custody and then formally placed under investigation on 8 April for manslaughter and causing injury, aggravated by deliberate breach of a safety obligation. He was released under judicial supervision. His alcohol and drug tests were negative. Béthune public prosecutor Étienne Thieffry assigned the case to the Pas-de-Calais judicial police.

The CGT railway workers' union called for full light to be shed on the circumstances. The accident is a reminder of how much the road-rail interface weighs in French railway accident statistics, as the black summer of 1985 and its Saint-Pierre-du-Vauvray level crossing collision showed.

• Date: 7 April 2026, around 06:45–06:50
• Train: TGV 7304 Dunkerque – Paris-Nord, about 160 km/h
• Location: PN 96 (SAL4), Mazingarbe / Bully-les-Mines
• Casualties: 1 killed (the driver), 16 injured including 2 seriously
• Convoy: military mobile bridge of about 70 tonnes, with pilot vehicle

Update (October 2026)

Rail services between Béthune and Lens resumed on 15 April 2026, three days earlier than first announced, after the power car was lifted and the crossing equipment rebuilt. The crossing reopened to road traffic on 19 April.

In late April, Ville, Rail & Transports reported the BEA-TT's main lines of inquiry: how the abnormal-load permit was issued and whether the haulier kept to the authorised route. As of early October 2026 the case is still listed among the BEA-TT's ongoing investigations, with no interim report published. Its recommendations on managing abnormal loads at level crossings are the next milestone to watch; follow our maintenance and safety coverage for developments.
