Border Crossings: Belgium - France
(Arlon -) Athus SNCB - Mont St. Martin yard (- Longwy) SNCF
see next item.
(Dinant - Halanzy -) Y Aubange SNCB - Mont St. Martin (- Longwy) SNCF
[E] The Athus - Mont St. Martin route closed and was lifted, but in 2002 it was restored, with a lead from Y Aubange instead of Athus: in other words, the initial route which gave through running from the Arlon direction to Mont St. Martin was (after an interval of some years with no direct access from SNCB to Mont St.Martin) replaced by one giving through running from the Dinant direction instead.
Dinant SNCB - Givet SNCF
[D] No traffic. Track impassable due to lack of maintenance. Since the tourist service was withdrawn in 2000 there have been various proposals for reopening. However, no funding is available and Wallonie region (BE) is suggesting it be converted to a cycle path.
(Mariembourg -) Treignes SNCB - Vireux-Molhain SNCF (- Charleville-Mézières)
The track is lifted beyond Treignes with the tunnel of Najauge having been used to grow mushrooms after closure.
(Mariembourg -) Momignies SNCB - Anor SNCF
The line within Belgium between Mariembourg and Momignies - which saw local freight use until 1999 - is out of use and some sections have been converted to a cycleway. The cross-border section between Momignies and Anor closed to passengers in 1953 and freight in 1978. In 1993 that section was acquired by Comptoir Calcaires & Matériaux, owners of a quarry at Wallers-en-Fagne in France (trading as Carrières de Wallers). Traffic was then taken by road to Momignies and thence by rail to Anor, worked by Colas Rail as a private siding. A new alignment, wholly within France and running direct to the quarry, came into operation on 19 July 2011, leading to the closure of the cross-border section and cessation of loading at Momignies. A descriptive article appears in Voie Etroite no. 254 (Feb-Mar 2013).
(Charleroi -) Erquelinnes SNCB - Jeumont SNCF (- Aulnoye)
[E*] 3kV dc extends to Jeumont, where there are switchable tracks in the station and freight sidings, although a gradually increasing number of freight trains are being hauled by dual- or multi-system locos (SNCB type 13 or appropriately equipped and certified TRAXX).
From the December 2018 timetable changes two trains a day use this crossing in each direction. These services were withdrawn from Monday December 6th 2021 in a round of planned cancellations attributed to staff shortages due to Covid. After briefly being reinstated, they were withdrawn again from Jan 26th due to Covid.
In the December 2022 timetable change, the local service between Charleroi and Erquelinnes is extended to Maubeuge every 2 hours. This is alternate trains on M-F (when the service is hourly) and all trains SSu (when the service is only 2 hourly).
This route is also used by the Brussels / Paris EC (Ouigo) services when engineering work prevents use of the route between Brussels, Mons and Quévy. This happens on a number of weekends during 2025, an exhaustive list is not available and would likely become out of date.
(Mons -) Quévy SNCB - Feignies SNCF (- Aulnoye)
[E*] 25kV 50Hz extends to Quévy where there used to be switchable tracks in the passenger station and freight sidings. From 14 December 2008 the regional passenger train service over this route (Quévy <=> Maubeuge/Aulnoye) was withdrawn and the Paris - Berlin/Hamburg night train was diverted to run via Forbach. There were thus no passenger trains over this border crossing for several years. From December 2018, two trains each way used this route until they were withdrawn at the December 2022 timetable change. These coasted through a long neutral section past the station at Quévy and were unable to call as it seems there are no longer switchable tracks.
Locomotive operated services between Paris and Brussels were temporarily re-introduced during the 2024 Olympics and Paralympics and are included in the 2025 timetable although their actual operation was delayed by a few days. These call at Mons and Aulnoye and coast past Quévy. When engineering work in Belgium blocks the route between Brussels, Mons and Quévy, these are diverted via the border crossing between Erquelinnes SNCB and Jeumont SNCF.
(St.Ghislain -) Quiévrain SNCB - Blanc-Misseron SNCF (- Valenciennes)
[D] Line closed. The cross-border passenger service, operated by SNCB and running only to Blanc-Misseron was withdrawn on 3 June 1984; freight traffic ceased on 15 April 1992. St-Ghislain – Quiévrain was electrified from 28 May 1995, whereupon the line was severed and lifted south of Quiévrain.
In 2013, both governments approved reopening in principle, but the money for this was reallocated to extension of the Valenciennes tram system to Vieux-Condé. However, some money has been allocated in the new regional plan.
(Bruxelles -) Antoing SNCB - Frétin SNCF (- Lille/Paris) {high-speed line}
[E] Electrification at 25 kV 50Hz is to SNCF standards as far as the end of the high speed line at Lembeek (15 km from Bruxelles), with neutral sections there and at the intermediate access points near Antoing and near Ath. Only trains equipped with TVM430 cab signalling can use this line.
(Tournai -) Froyennes SNCB - Baisieux SNCF (- Lille)
[E*] A neutral section just west of Froyennes separates SNCB and SNCF electrification and only dual-system electric motive power can use the line. Initially, most local passenger trains continued to be worked by SNCF diesel units, but now SNCB dual-system EMUs run hourly between Lille and Liège.
(Kortrijk -) Mouscron/Moeskroen NMBS - Tourcoing SNCF (- Lille)
[E*] The neutral section between the SNCB 3kV and the SNCF 25kV 50Hz is a few kilometers south of Mouscron. Passenger services between Lille and Brugge and between Lille and Antwerpen via Gent are worked by SNCB dual-system EMUs. SNCB dual-system electric locomotives work freight trains through to Lille.
De Panne NMBS - Bray Dunes SNCF (- Dunkerque)
[D] No traffic. The section of line between Bray Dunes and Dunkerque is partly dismantled.
