rolland.track.ContBallastedSingleRailTrack

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

Bases: BallastedSingleRailTrack

Single rail slab track with ballasted support.

All superstructure properties are continuous along the track.

Note

Properties of ballast need to be defined as continious values (per meter).

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

Parameters:

• args (t.Any)

• kwargs (t.Any)

rail

Rail instance.

Type:

Rail

pad

Continuous pad instance.

Type:

ContPad

slab

Slab instance.

Type:

Slab

ballast

Ballast instance.

Type:

Ballast

l_track

Track length \([m]\). (May change slightly after discretization. The inclusion of boundary and calculation domain is required).

Example

>>> from rolland.database.rail.db_rail import UIC60
>>> from rolland.components import ContPad, Slab
>>> from rolland.track import ContBallastedSingleRailTrack

>>> thepad = ContPad(sp = [300*10**6, 0], dp = [30000, 0])
>>> theslab = Slab(ms = 250)
>>> track = ContBallastedSingleRailTrack(rail = UIC60, pad = thepad, slab = theslab)
