APPLICATION
3.1
Product destination
Automatic Level Crossing System is destined to assure safety on crossings of
railway tracks and public roads. It automatically warns road users about trains
approaching to the crossings. It can be installed on level crossings with barriers or
half barriers situated on one- or more-track railway lines equipped with electrical
traction or having no traction at all. Railway line can be equipped with line block of
any technology or it can have no such system.
SPA-5/LVA system must be able to ensure safe rail and road traffic operation at
following crossing types:
a) Unguarded level crossings equipped with automatic light signalling (train-
operated or operated from the station interlocking system)
b) Guarded level crossings equipped with automatic warning light signalling and
with automatic or semiautomatic barrier booms of electrical gate machines (barrier
booms close automatically but open by means of button pressing by gate keeper)
c) Unguarded level crossing equipped with automatic light signalling with
automatic barrier booms of electrical gate machines, which may have a
supervisory monitoring at the nearest station and C.T.C control office.

Product description
Automatic Level Crossing System SPA-5/LVA is designed in accordance with
requirement specification defined by Latvian Railways.
Technical data of the system is presented in paragraph 4.1.
SPA-5/LVA is connected with Ebilock interlocking system. Ebilock is responsible to
send engagement and disengagement commands to LX. Depending on the
system state (engagement or disengagement) warning devices perform their tasks
according to the requirements. In case of guarded crossings a control panel is
used to enable operations of the gate keeper.
Information about LX status is sent to the remote control device that is placed in
the dispatcher’s room. Remote control device enables supervision of the LX
system operation and logging of events and faults.

Application scope
The number and type of equipment applied in the LX system can be defined for
each specific application. The version of a control unit as well as all the facilities of
the LX system can be adapted according to the specific requirements and
configuration of any crossing. Product symbol (4.6) defines the most important
