calculation of vertical distance between the top of rail and the level of right edge of the track base sketch calculations
rail height tie plate + cushion thickness tie height ballast depth level difference between the point under rail and edge of track base
total [m]
elevation of top-of-rail (PGS) elevation of the right edge of the track base
Terrain conditions
terrain profile along the road centreline; scale 1:500/10.
terrain profile along the railway line centreline; scale 1:500/10.
terrain elevation at the intersection point S
(determine from the map) 135.
elevation of top-of-rail, relative to terrain
level at point S (from the assignment sheet) + 1.
elevation of top-of-rail at the crossing
(calculate) 136.
elevation of the right edge of the track base at
the crossing (calculate) 136.
Drainage of the crossing
sketch brief description
Along the road route terrain falls
towards North.
Along the railway line terrain falls
towards East.
It is proposed to use 1 culvert under
the road, in line with railway side
ditches.
Visibility conditions from the road
intersection angle
(determine from the map) 85°
proposed crossing category C – protected, signalised
visibility conditions at the crossing (visibility triangle) sketch calculations
For a one track railway:
L = 5.5 * Vmax = 5.5 *75 = 412.5 m
L 1 = 3.6 * Vmax = 3.6 *75 = 270.0 m
Road pavement at the crossing
pavement type MIROSŁAW UJSKI
brief characteristics
Pavement of this type consists of small-scale concrete slabs, working
well with the railway track structure. It is not very susceptible to
deformation.
justification of pavement selection
This pavement is suitable for this railway line category and crossing
located in a built-up area.
