Dividing train
A dividing train is a train that separates into two trains partway along its route, so as to serve two destinations.
Operation[]
On the initial leg of its journey, the train is driven as normal by a single crew. At a designated station before a junction, the train stops and some of the cars are detached, with passengers or goods still on board. The front part of the train then departs to run the remainder of its route. A second train is then formed from the detached cars, the points are changed at the junction, and a new crew drives the train on a different route to a second destination. Where the train is formed of multiple units – self-contained trainsets with their own propulsion and driving cabs – two or more units work in multiple on the first leg. After detachment, the second crew drives in the trailing unit's front cab.
On the return journey, the two trains may join at the same station where they divided. Special signalling is required at the station, both to recognise the division of the outbound train as intentional, and to allow the two inbound trains to enter the same block. The British rail network uses a draw ahead signal for the latter.[1]
Examples[]
Australia[]
- Canberra Monaro Express – Sydney Central to Canberra and Cooma dividing at Queanbeyan (1955–73 and 1986–88)
Belgium[]
- IC trains between Genk and Knokke or Blankenberge (IC 1527–1542) used to be divided in Bruges, the front part went to Knokke (IC 1627–1642) while the rest continued to Blankenberge and the same occurred on the return leg (IC 1505–1520). The consists were either made up with AM96 EMU's (enable passage from set coach to another) or M6 coaches hauled by Class 19 locomotives. In the latter case, cab cars and engines are fitted with automatic couplers to allow quick separation. On periods with high affluence or when facing problems, these IC trains could run entirely to one destination (usually Blankenberghe) and another trainset was be provided for the leg between Bruges and Knokke. This dual service ended with the new transport timetable introduced in December 2017. Now, separate trains are used for each destination.[2]
- despite not being advertised as coupling trains, some IC trains between Lille Flandres and Tournai are then coupled with one or two AM96 trainsets going from Tournai or Kortrijk to Namur, therefore allowing to travel directly from Lille to Namur.[3]
- The same happens with IC trains Between Lille Flandres and Mouscron. At Mouscron, they are coupled with AM96 multiple units which then run IC trains between Mouscron and Antwerp Centraal.[3]
Canada[]
Route | From | Dividing at | Destination | Remarks |
---|---|---|---|---|
Montreal–Senneterre train | Montreal Central Station | Hervey-Jonction station | Senneterre station | |
Montreal–Jonquière train | Jonquière station |
Germany[]
- There are several dividing regional and high-speed trains all over Germany. ICE trains from Munich often split at Hanover into sections for Bremen and for Hamburg. ICE from Berlin split at Hamm into sections for Cologne and for Düsseldorf.
- Hanover Stadtbahn: In the evenings and on Sundays the lines 2 and 8 of Hanover's light rail system work with dividing trains. Trains start in Alte Heide as line
2and divide in Peiner Straße stop. One part continues as line 8 to Messe Nord, the other as line 2 to Rethen. In the other direction, trains reconnect at Bothmerstraße station and run as line 2 to Alte Heide. - Hamburg S-Bahn: The trains on the line S1 of Hamburg's S-Bahn system usually split at Ohlsdorf into sections for Hamburg Airport and for Poppenbüttel.
- Since 2014, the Regional-Express services RE 1 Mannheim–Saarbrücken–Trier–Koblenz and RE 11 Luxembourg City–Trier–Koblenz operate jointly with trains dividing in Trier main station. The RE 1 part is operated by the German DB Regio South-West with a Stadler FLIRT single-deck EMU as part of the network, while the RE 11 part is operated by the Luxembourgish Société Nationale des Chemins de Fer Luxembourgeois with a double-deck Stadler KISS EMU. This is probably the only situation where a single-deck and a double-deck train of two countries' national railways divide
- Since 2018, the Regional-Express service RE 7 Hamburg–Elmshorn–Neumünster–Kiel/Flensburg is split in Neumünster with the front train continuing to Kiel, the rear to Flensburg.
Japan[]
There are several dividing train services in Japan, and each route has its own name.
Route | From | Dividing at | Destination | Remarks |

Hayabusa | Shin-Hakodate-Hokuto Station | |||
Sunrise Izumo | Tokyo Station | Okayama Station | Izumoshi Station | Overnight sleeper services |

United Kingdom[]
Dividing trains operate on several lines on the British railway network, commonly (although not exclusively) in the south of the country. To ensure consistent journey times, the front part of a dividing train usually becomes the rear of the returning service when it reunites.
In addition, some services discard carriages part-way along the route, & pick them back up on the return journey. This may be because a portion of the line has short platforms at a number of its stations, or because of demand being much higher on one section than another.
Route | From | Dividing at | Destination | Remarks |
---|---|---|---|---|
Arun Valley line[4] | London Victoria | Crawley or Horsham | Front part non-stop to Barnham, then major stations to Portsmouth Harbour or Southampton Central | On Sundays calls at all stations to Barnham & divides there. |
Rear part most or all stations to Bognor Regis | ||||
Caledonian Sleeper[5] (Lowland) | London Euston | Carstairs | Front part to Edinburgh Waverley | |
Rear part to Glasgow Central | ||||
Caledonian Sleeper (Highland) | Edinburgh Waverley | Front part to Inverness | ||
Middle part to Aberdeen | ||||
Rear part to Fort William | ||||
Cambrian Coast Line | Birmingham New Street | Machynlleth | Front part to Aberystwyth | Both parts call at Dovey Junction, but use separate platforms & therefore must divide one stop earlier. |
Rear part to Pwllheli | ||||
Caterham line Tattenham Corner line |
London Bridge (some peak-time trains start from Victoria)[6] | Purley | Front part to Caterham | Colloquially known as the "Cat & Tat". Was the most common service pattern on the branches from Purley before resignalling work made them an extension of the Brighton Main Line local tracks. |
Rear part to Tattenham Corner | ||||
Chatham Main Line[7] | London Victoria | Faversham | Front part to Ramsgate | |
Rear part to Dover Priory | ||||
Fen line[8] | London King's Cross | Cambridge | Front 4 carriages to all stations to King's Lynn | |
Rest of train discarded at Cambridge | ||||
South West Main Line | London Waterloo | Southampton Central or Bournemouth | Front 10 carriages to Weymouth | Most Dorset stations beyond Bournemouth have short platforms, while as far as Poole the front train forms the principal express service on a heavily trafficked line, with the back train operates as a stopping service. |
Last 5 carriages to Poole or Bournemouth | ||||
West of England Main Line | London Waterloo | Salisbury | Front part to Exeter St Davids | |
