SWITCHES
CROSSINGS
Curved and Trap
Switches
Rahee produces Curved Switches
as per the client needs. Curved
switch tongue rails are curved
according to the curvature of
the turnout from the toe to heel
of the switch. Curved tongue
rail allows for smooth turning
of trains, and are used for the
specific curvature for which they
are designed.
Trap switch is used to protect
main railway lines from
unauthorized vehicles moving
onto them from sidings or
branch lines. A single tongue trap
consists of only one tongue rail
assembled with one stock rail and
one single stock rail.
Thick Web Switches
These Switches are made from
specific asymmetrical Tongue
Rail sections, forged at the end
to match standard rail sections.
The transition from one section
to the other lies mostly in the
clamped area at the end of the
switch. Thus welding is not
required in the flexible area.
The length of the forging can
be adjusted to the specific
requirement such as welding,
insulated fishplating or
emergency fishplating. In order
to reduce setting forces and to
influence the elastic strength
of the switch, the base of the
switch rail is milled in the
flexible area.
Heat Treated Welded Crossing (HTW)
Rahee’s HTW crossing is a monolithic structure, where the
Vee is formed from two separate pieces of rails, with a steel
plate sandwiched in between. The plate is Electro-slag
welded and machined to form a solid nose. The weld metal
hardness, at the top of the rail head and in the weld cross
section, ranges from 330 to 360 BHN.
The Wing Rails are head hardened through induction
hardening method with subsequently controlled cooling,
to obtain fine pearlite grain structure. The Wing Rails and
the Vee are bolted together by high tensile bolts, to form
a complete HTW crossing. These crossings can withstand
axle loads as high as 25 tones under varying traffic
conditions and can be welded to the adjoining rails.
HTW crossing can be designed and manufactured as per
the client’s specific requirements. Rahee has supplied
various types of HTW crossings such as Acute, Obtuse,
Diamond, Curved, Extended Nose Type, and Crossings with
clothoidal entry.
Rail End Forging
Facility
Rahee’s rail end forging facility is
one of the most modern facility
with capacities to forge over
8000 rails annually. Rahee has
the ability to forge rails in various
lengths and rail sections including
60E1A1, 54E1A1 and many more
as per the client requirement.
Head Hardening
Facility
Rahee’s continuous inductive
hardening process hardens rails
up to 360 BHN and increases rail
strength from 900 kg/mm 2 to
1080 kg/mm
Rahee’s state-of-the-art facilities design and manufacture switches as per client’s requirements.
Rahee designs and manufactures Crossings as per Railway requirement.
Cast Manganese Steel
Crossings (CMS)
Rahee can design and supply Turnouts with
Cast Manganese Steel Crossings (CMS). CMS
Crossing has longer life, higher strength and
offers more resistance to wear. They can be
supplied with conventional fish plated joints
and in weldable joint format, as per client
preference.
In Weldable CMS, the crossing is welded
with the adjacent rails to run the continuous
welded rail (CWR) through Turnouts.
Weldable CMS crossings as compared to the
conventional crossing, offers higher service
life and better riding qualities.
