Returns a list of all track circuits including those on pocket tracks and
crossovers. Each track circuit may include references to its right and left
neighbors.
Usage
track_circuits()
Arguments
Value
A data frame of nested track circuit information.
Format
A nested tibble with 1 row per train and 9 variables:
Track
Track number. 1 and 2 denote "main" lines, while 0 and 3 are
connectors (between different types of tracks) and pocket tracks,
respectively.
CircuitId
An internal system-wide uniquely identifiable circuit
number.
Neighbors
Data frame containing track circuit neighbor information.
Note that some track circuits have no neighbors in one direction. All track
circuits have at least one neighbor.
NeighborType: Left or Right neighbor group. Generally speaking, left
neighbors are to the west and south, while right neighbors are to the
east/north.
CircuitIds: Data frame containing neighboring circuit IDs as list
column.
