Scheme description / Schemenbeschreibung

Position of operationMode in the XML-Tree / Position von operationMode im XML-Baum

Multiplicity / Anzahl


Semantics / Bedeutung

The element <operationMode> defines the operational system that is used at all tracks where the current <infraAttributes> are used per reference.

Attributes of operationMode / Attribute von operationMode

Missinginformation.png In this article there is information missing with respect to attribute semantics. Please help improving the railML® wiki by filling the gaps. Possibly, you will find further details on the discussion pageFerri Leberl (talk) 15:55, 16 January 2017 (CET)

  • clearanceManaging Possible values are:
  • sight used while any other kind of signalling is unavailable.
  • time clearance is guaranteed through the amount of time a train leaves the block section completely.
  • blocking means to guarantee a minimum distance between trains running in the same direction and to guarantee that two trains running in opposite directions are not in the same section of track simultaneously. The source of definition is IEC 60050:821-06-01.
  • LZB-blocking Continuous Train Control (LZB) transmits data continuously and bidirectionally. With LZB, a train can be automatically brought to a halt and can additionally be controlled. LZB consists of a line cable that is laid in the form of a loop in the track and an LZB radio block centre. Data telegrams are transmitted from the vehicle to the radio block centre and vice versa, via the line cable ETCS migration planning in Germany (external link).
  • absBrakeDist wheel slide control systems. The most common of these operates rather like ABS (automatic braking systems) on road vehicles. The railway systems usually monitor the rotation of each axle and compare rotational speeds between pairs of axles. If a difference appears between a pair of axles during braking, the brake is released on those axles until the speeds equalise, when the brake is re-applied. All this occurs automatically. Modern systems also detect too rapid deceleration of an axle. Another form of slip/slide detection uses Doppler radar techniques. This measures the ground speed of the locomotive against the revolutions of each wheelset and uses the detection of a difference to regulate the control systems Integrail Glossary (external link).
  • other:anything: Any value that does not fit any value from the previous enumeration list, fulfilling the constraint: at minimum two characters, whitespace is not allowed. Please, apply Dev:usingAny accordingly.
