Tram-train

From Wikipedia, the free encyclopedia
This article is about trams sharing tracks with main-line railways. "Tram-train" can also refer to a train of two or more coupled trams operating on a regular tramway.
"Train-tram" redirects here. For the Siemens-Duewag train-tram, see RegioSprinter.

The Zwickau Model has main-line lightweight diesel tram-trains running through urban streets. Because the trams are metre gauge and the trains standard gauge the shared tracks are dual-gauge, with one shared rail and one exclusive rail for each.

A tram-train is a light-rail public transport tram vehicle which runs through from an urban tramway network to main-line railway lines which are shared with conventional trains. This combines the tram's flexibility and accessibility with a train's greater speed, and bridges the distance between main railway stations and a city centre.

There is also a train-tram, which is a train modified to also run on tramlines. Generally, the tram-train and train-tram are interchangeable, although a train-tram is based on a train design modified to also run as a tram and a tram-train is based on a tram design modified to also run on a train line.

The tram-train concept was pioneered with the Karlsruhe model in Germany, and has since been adopted in Mulhouse in France and in Kassel and Saarbrücken in Germany.

Technology[]

The tram-train often is a type of interurban,[1] i.e. they link separate towns or cities. according to George W. Hilton and John F. Due's definition.[2]

Most tram-trains are standard gauge, which facilitates sharing track with main-line trains. Exceptions include Alicante Tram and Nordhausen, which are metre gauge.

Tram-train vehicles are dual-equipped to suit the needs of both tram and train operating modes, with support for multiple electrification voltages if required and safety equipment such as train stops and other railway signalling equipment. The Karlsruhe and Saarbrücken systems use "PZB" or "Indusi" automatic train protection, so that if the driver passes a signal at stop the emergency brakes are applied.

History[]

The idea is not new; in the early 20th century, interurban streetcar lines often operated on dedicated rights-of-way between towns, while running on street trackage in town. The first interurban to emerge in the United States was the Newark and Granville Street Railway in Ohio, which opened in 1889. In 1924, in Hobart, Australia, sharing of tracks between trams and trains was proposed.[3]

The difference between modern tram-trains and the older interurbans and radial railways is that tram-trains are built to meet mainline railway standards, rather than ignoring them. An exception is the United States' River Line in New Jersey which runs along freight tracks with time separation: passenger trains run by day, and freight by night.

  • Austin, Texas: Capital MetroRail – commuter rail that shares more commonality with tram-train operation, with downtown street running and usage of mainline track. Uses diesel multiple units.
  • New Jersey: River Line – diesel multiple units using main line tracks between Trenton, New Jersey and Camden, New Jersey in a time-sharing agreement with the freight companies.
  • Salt Lake City: TRAX uses former Denver and Rio Grande tracks as well as street trackage to service Salt Lake City. Between the hours of midnight and six in the morning, Union Pacific freight trains use much of the trackage, up to just past 2500 S to service a number of industries along the line.
  • Oceanside: – Escondido: Sprinter uses track also used by BNSF for freight at night in the Escondido branch and also share track with Coaster Metrolink and Amtrak
  • San Diego: The MTS blue line is used at night for freight for the SD&IV
  • Puebla, Mexico: Puebla-Cholula Tourist Train

Proposed systems[]

Africa[]

  • The October 6th Tram system (The O6T), Cairo, Egypt

Asia[]

Europe[]

  • Braunschweig, Germany
  • Bratislava, Slovakia
  • Erlangen, Germany – an extension of Straßenbahn Nürnberg not initially planned to use mainline rail tracks but proposed to do so in the future. The planned line to Herzogenaurach replicates a former mainline rail line
  • Grenoble, France
  • Groningen, Netherlands
  • île de France (Paris region), France. The system is called Tram Express by the transport authority STIF: 1 line already exists (Tramway Line 11 Express) and 2 lines are scheduled (Tramway Lines 12 Express and 13 Express). The light train rolling stock will only roll on national rail network in western line (Line 13 Express) a short section of 3.6 km (2.2 mi) is an urban tram section of the 19 km (11.8 mi) line. The southern line (Line 12 Express ) is a 20 km (12.4 mi) line, 10 km will be tram section and the 10 km another will roll on national rail network.

United Kingdom[]

A two-year tram-train pilot project is being undertaken between Sheffield and Rotherham. In the initial phase, from October 2017, Stadler Citylink tram-train vehicles (British Rail designation Class 399) were introduced onto the Sheffield tram network only. Late in 2018, with the completion of a chord at Tinsley connecting Rotherham Parkgate with Meadowhall Interchange, the tram-train vehicles operate on national rail tracks.[10] If the trial proves successful, similar schemes could be rolled out across the UK.[11][12]

In March 2008 the Department for Transport released details of a plan to trial diesel tram-trains on the Penistone line for two years starting in 2010.[13] There was no commitment to connect them to the Sheffield tram network, and in September 2009 the idea was withdrawn as it was deemed not economically viable for a trial due to the cost of the extra development required for the diesel engines to meet the forthcoming stringent EU emission regulations. Instead single-voltage electric tram-trains will be trialled between Rotherham and Sheffield.[14]

A tram-train trial in the Manchester area was ruled out as the Department for Transport wanted to try low-floor tram-trains, whereas Manchester Metrolink cars have high floors.[15]

In August 2009 the Liverpool Daily Post reported that a new Merseyrail tram-train link to Liverpool John Lennon Airport was under consideration. The Merseyrail Northern line and the City line between Liverpool Lime Street and Liverpool South Parkway were being assessed. From South Parkway the tram-trains would transfer seamlessly to a new tramway. A link from Edge Hill in the east of the city to the Liverpool Arena at Kings Dock near the city centre was also considered.[16]

Oceania[]

  • Adelaide, South Australia – On June 5, 2008, the Government of South Australia announced plans for train-tram operation on the Adelaide Metro's Outer Harbor/Grange train lines and City West-Glenelg tramline extension as part of a 10-year A$2 billion public transport upgrade.[17]
