Section 150
Section 1500.170 Buildings
and Miscellaneous Structures
a) Structures Adjacent to Main Tracks. Except as otherwise
specified the clearances between main tracks and buildings or other structures
adjacent thereto shall be as follows: Beginning at a point in the centerline
of track 21½ feet above the top of rail the vertical clearance line shall
extend thence horizontally each way to points 8 feet from the centerline of
track, from which points the horizontal clearance lines shall extend vertically
downward to points level with the base of rail.
b) Structures Adjacent to Subsidiary Passenger Tracks. Except as
otherwise specified, the clearances between subsidiary passenger tracks and
buildings or other structures adjacent thereto shall be as follows:
1) Tracks outside of buildings: Beginning at a point in the centerline
of track 21½ feet above top of rail, the vertical clearance line shall extend
thence horizontally each way to points 7½ feet from the centerline of track,
from which points the horizontal clearance lines shall extend vertically
downward to points level with the base of the rail.
2) Tracks entering buildings: Beginning at a point in the centerline
of track at such a height as will be most practicable for the height of cars
handled on such tracks, the vertical clearance line shall extend thence horizontally
each way to points 7 feet from the centerline of track from which points the
horizontal clearance lines shall extend vertically downward to points level
with the base of rail.
c) Structures Adjacent to Subsidiary Freight Tracks. Except as otherwise
specified the clearances between subsidiary freight tracks and buildings or
other structures adjacent thereto shall be as follows:
1) Tracks outside of buildings: Beginning at a point in the centerline
of track 21½ feet above the top of rail the vertical clearance line shall
extend thence horizontally each way to points 8 feet from the centerline of
track, from which points the horizontal clearance lines shall extend vertically
downward to points level with the base of rail.
2) Tracks entering buildings such as warehouses, freight houses,
coal chutes, elevators and similar structures: Beginning at a point in the centerline
of track at such a height as will be most practicable for cars handled on such
tracks, the vertical clearance line shall extend thence horizontally each way
to points 7 feet from the centerline of track, from which points the horizontal
clearance lines shall extend vertically downward to points level with the base
of rail.
d) Engine Houses. The clearances at the entrances of new engine
houses when the engine house doors are open shall be as follows: Beginning at
a point in the centerline of track at such a height as will be most practicable
for the height of engines using the engine house, the vertical clearance line
so established shall extend horizontally each way until it intersects the
horizontal clearance lines established 6¾ feet laterally distant from the centerline
of track, from which points the horizontal clearance lines shall extend
vertically downward to points level with the base of rail.
e) Coal Tipples, Ore Tipples, Stone Crusher, etc. The clearances
of all subsidiary tracks passing through or underneath coal tipples, ore
tipples, stone crushers or similar overhead structures shall be as follows:
Beginning at a point in the centerline of track at such height as will be most
practicable for the height of equipment handled on such tracks, the vertical
clearance line shall extend thence horizontally each way to points 8 feet from
the centerline of track, from which points the horizontal clearance lines shall
extend vertically downward to points level with the base of rail.
