rolland.track.SimplePeriodicBallastedSingleRailTrack

class rolland.track.SimplePeriodicBallastedSingleRailTrack(*args, **kwargs)

Bases: DiscrBallastedSingleRailTrack

Single rail ballasted track with simple periodic support.

All mounting properties are uniform and no variation is allowed.

Note

Properties of ballast need to be defined as discrete values.

Layer	Component	Condition	Variability
/	rail	continuous	no
1st	pads	discrete	no
1st/2nd	sleeper	discrete	no
2nd	ballast	discrete	no

rail

Rail instance.

Type:

Rail

ballast

Ballast instance.

Type:

Ballast

pad

Continuous pad instance.

Type:

ContPad

sleeper

Sleeper instance.

Type:

Instance of sleeper class

distance

Distance between mounting positions.

Type:

float

num_mount

Number of mounting positions.

Type:

int

mount_prop

Dictionary for discrete mounting positions (x-> (Pad, Sleeper)).

Type:

dict

l_track

Track length \([m]\). (May change slightly after discretization. Results from the number of mounting positions and the mounting distances).

Type:

float

Example

>>> from rolland.database.rail.db_rail import UIC60
>>> from rolland.components import DiscrPad, Sleeper
>>> from rolland.track import SimplePeriodicBallastedSingleRailTrack

>>> thepad = DiscrPad(sp = [300*10**6, 0], dp = [30000, 0])
>>> thesleeper = Sleeper(ms = 150)
>>> distance = 0.6
>>> tr = SimplePeriodicBallastedSingleRailTrack(
...     rail=UIC60,
...     pad=thepad,
...     sleeper=thesleeper,
...     distance=distance)
