RUMA system data

The RUMA system is used to design and implement track works using track work notifications. RUMA is also used to report traffic restrictions with traffic restriction notifications.

Track work notification

In addition to basic information the notification contains the track work’s location(s). Below is a description of the notification structure.

Work part

Describes a logical part of a track work. Consists at least of a single location. Work parts are numbered (index).

Traffic restriction notification

In addition to basic information the notification contains a possible link to a track work notification. The notification also has a restriction type, possible types are:

  • Closed from traffic
  • Closed from electric rolling stock
  • Temporary speed limit
  • Max axle weight
  • ATP construction zone
  • Switch locked
  • Fire work danger zone

A traffic restriction notification references railway infrastructure directly and not through work parts.

Location of traffic work or restriction

Below is a description of concepts with which traffic work notifications and traffic restriction notifications reference railway infrastructure.

Location

Always related to an operating point or a section between operating points. The location type describes the type of work: allowed values are WORK, FIREWORK, SPEED_LIMIT. If the location doesn’t contain any identifier ranges, the work location is the whole operating point/section.

Identifier range

Describes either:

  • An area between two elements. This area consists of one or multiple element ranges.
    OR
  • The allocation of a switch. An identifier range with a switch and no element ranges implies that the switch is not usable for traffic.
    OR
  • Some ambiguous route between two elements (element pair).

Element range

Element ranges form an unambiguous route between two elements (multiple routes could be possible otherwise). Elements can be only limiting elements of a certain type: limiting signal, switch, buffer, stop board, operating point boundaries, traffic management boundaries.

Specifier

Specifier designates a non-limiting element inside an element range. Allowed specifier types are: level crossing, balise, non-limiting signal.

Limiting signal types

Below are Infra-API signal types designated in RUMA as limiting. Other signal types are non-limiting.
