Expert Testing of Leipzig Sub-Control Centre Nodes
Leipzig station is Europe’s largest railway terminus. Within the framework of the modernisation of the station’s track equipment, GQS is responsible for the supervision of the first commissioning stage.
Due to its size, the upstream node area imposes special requirements on
the planning and testing of the new computerised signal box technology.
The latest changes to the track technology involve revisions of the
basic plans as a result of order changes and adaptations of the
signalling planning, Part 1, to the special signal box system
requirements.
On October 29, 2002, the DB Projektbau GmbH awarded the handling of the
first commissioning stage to the Gesellschaft für Qualitätssicherung
und Qualitätsüberwachung mbH (GQS). The focus was on the testing of
Part 2 of ALCATEL SEL signalling planning and was carried out in two
stages:
- First stage: commissioning of sub-control centre Leipzig main
station east side (Uz Ost) with the computerised signal module (ESTW A)
East Leipzig area and computerised sub-control centre Neuwiederitzsch
and adaptation of control district 5 of the operation control centre
Leipzig on November 23, 2003.
- Second stage: commissioning of sub-control centre West (main
station) with the computerised signal module in station North Leipzig
(ESTW A) and the adaptation to blocking system EBL 2000 adaptation
Leipzig-Leutzsch, and adaptation of sub-control centre East to the
commissioned sub-control centre West. Adaptation of the operation
control centre Leipzig and of the signalling and control system of the
sub-control centre and control centre areas.
The test period ran, with a few short interruptions, from November 2002
to September 2004. Tests for the West sub-control centres were related
to five hardware and software versions of the second construction stage
and for the East sub-control centres to 15 hardware and software
versions of the first and second construction stage, including the
adaptations of the East sub-control centres to the West sub-control
centres.
Order of magnitude:
Commissioning stage 1
Sub-control centre Leipzig East with computerised signal module in
station East, 4 interlocking modules, 8 field modules, 17 axle counter
calculators, 145 points and derailers, 16 electrically operated points,
90 main signals, 8 6 shunting signals, 258 axle counting points, 3
blocking system adaptations. Two interfaces to old signal box equipment
on the west side, 1 two-track level crossing with signal interlocking.
Commissioning stage 2
Sub-control centre Leipzig main station with electronic signal module A
North and adaptation to blocking system EBL 2000 Leipzig-Leutzch, 6
interlocking modules, 11 field modules + 2 modules for optional
extension of the ‘City Tunnel’, 15 axle counter calculators, 125 points
and derailers, 24 electrically operated points, 100 main signals, 69
shunting signals, 227 axle counting points, first application of a
sub-control centre adaptation for electronic signal box Alcatel SEL
type L90, within the station area, with 2 interfaces each. Seven
blocking system adaptations, including 2 to EBL 2000 in the
Leipzig-Leutzsch station. On the west side alone, approx. 400 train and
shunting routes were submitted to expert testing.
Further electronic signal box construction projects are planned in
order to evolve towards a new rationalised rail plan. The aim is to
ensure higher train travel speeds in the long run and to connect the
planned City Tunnel to the Leipzig station Bayrischer Bahnhof.

| Modernisation of signalling systems in Latvia |
|
| INGENO Europrojekte GmbH strengthens its presence in the Eastern European region: Alcatel SEL AG Stuttgart has entrusted the company with the implementation planning for signalling systems and underground cabling on the railway link between the Belorussian border near Indra and Ventspils, Latvia’s major port. In addition, INGENO Europrojekte GmbH has been awarded the order to manage and monitor the surveying works, as part of the basic analysis, on the so-called east-west corridor. |
