ERTMS Regional

from Wikipedia, the free encyclopedia

ERTMS Regional is a cost-optimized variant of the European Rail Traffic Management System for controlling and securing branch lines of the railway.

ERTMS Regional combines elements of ETCS with other, non- TSI- compliant components. The vehicle devices remain ETCS-compatible. This should reduce the costs for signaling infrastructure by around 40 percent.

features

  • ERTMS Regional mainly includes track technology. The completeness of the train must be monitored for the on-board device.
    • The special thing about ERTMS Regional is the lack of track vacancy detection systems compared to conventional systems, which also accounts for a large part of the cost reduction. Track occupancy is reported by cyclical position reports from the locomotives to the Train Control Center via GSM-R radio. The vehicles also have to check the train integrity. All vehicles that master ETCS Level 3 can still be used on ERTMS regional routes.
    • As with every vehicle equipped with ETCS, this position is determined on the basis of the Eurobalises (reference points) laid at regular intervals , which are designed as pure fixed-data balises. The position between the balises is determined by means of odometry . The train length required for track vacancy detection and the result of the train completeness check are entered manually by the driver.
  • At ERTMS Regional, only traction vehicles that are equipped with at least ETCS Level 2 can operate. Journeys with non-ETCS-equipped locomotives are possible as part of a special operating procedure. For this purpose, these locomotives are equipped with special GSM-R devices, with which the route for this train journey is blocked in cooperation between the dispatcher and the driver and then released again manually by both of them.
    • In order to keep the system simple, the parallel installation of additional train protection systems is prohibited in the specification.
  • The central element of ERTMS Regional is the Train Control Center (TCC). This is essentially a secure computer system that combines the functions of interlocking , ETCS control center (RBC) and automatic schedule-dependent control.
  • All communication with the vehicles and the track equipment takes place via the GSM-R radio system.
    • All elements of the route technology such as switches , side protection devices , level crossings or movable bridges are controlled and monitored directly by the TCC via so-called Object Controllers (OC). The communication between OC and TCC can take place via cable or via GSM-R.
    • If maneuvering has to be carried out, a predefined sub-area is set up as a maneuvering area in which only maneuvering drives then take place. The limits of the shunting areas are monitored by the TCC. After the shunting work has been completed, the tracks are entered in the TCC as "occupied" or "free" by the dispatcher and the shunting area is canceled.

history

development

The concept emerged from the UIC low-cost ETCS project , which was started in November 1997 . The first version of the ERTMS regional specification was published in March 2003. In June 2004, the Banverket was the first network operator to tender for a first pilot line, the 134 km, single-track Västerdalsbanan ( Borlänge - Malung ). The company received a number of low-cost offers and in March 2005 awarded the contract to Bombardier Transportation .

The technology was installed in 2009. The system was tested in the following two years. Commercial operation was finally started on February 21, 2012 on a trial basis. Two months later, the plant went into regular operation.

Further use

Due to increasing problems with outdated signaling systems, Denmark decided to completely switch to ETCS. Branch lines are also to be equipped with ETCS Regional (other name ETCS 3 ), which is planned for 2021. The main lines will be renewed beforehand.

Following the retrofitting of the Frederikshavn – Lindholm line on October 21, 2018, further commissioning on the main lines is planned as follows:

In Russia , an ETCS-compatible system ITARUS-ATC has been developed since 2007 . At a presentation in December 2015, the application of virtual balises using wheel sensors and satellite positioning was used as a substitute for position determination with Eurobalises . This means that the system is compatible with both ETCS L2 and ERTMS Regional in the Russian broad-gauge network.

ERTMS Regional is also to be used on a number of new corridor routes that are being considered or planned in East Africa.
