Railway Fish Plates, rail joint bars for joint rail fish plate in
railway
UIC standard railway fish plate, rail joint bar for rail track
construction
ZHONGYUE's railway fish plates, also called rail joints or joint
bars, offer a different function to other rail components. Rail
joints are flat metal plates usually used to connect adjacent two
rails with a number of rail bolts or railroad spikes.
Traditionally, railway fish plates are drilled with some holes on
the ends of the sections to be connected. There are some holes in
the end of railway track, which are used lined up with the holes in
the railway fish plate and jointed using a rail bolt. In general,
railway fish plates are made of steel, but plastics and composites
are alternative raw materials for rail joints.
Rail fish plate, also called rail joint bars, is one of the most
common kinds of rail fasteners. Below is the specific information
about rail fish plate.
Definition: to connect or joint rail tracks
A rail fishplate, also called splice bar or joint bar, is a device
used to connect the ends of two rails with bolts in a track. It can
be divided into 3 types according to light rail, heavy rail and
crane rail. The preferred spare part to fix a rail joint bar is
fish bolt set, which is always made of a fishtail bolt, rail nut,
flat washer and spring washer. Every 2 fishplates (one unit) need 6
or 4 fish bolts.Definition: to connect or joint rail tracks

There are bolt holes in the middle of a fishplate used in railway
track. Above and below the hole horizontal axis, there are up and
down working faces to touch the bottom of railhead and the top of
rail flange, respectively. The backside of above mentioned
up-working-face forms a transition section over the rail surface
while extending upward, which becomes a bridge-arc of high in the
middle but low at two ends, orientating along the length of the
rail joint bars. Such bridge-arc frame is simple, capable of
reducing the impact of carriage wheels to steel rail joints and
strengthening the continuity of longitudinal strain at the steel
rail joints in order to improve the train’s smooth passing.

Types of railway fish plates
UIC standard railway fish plate, rail joint bar for rail track
construction
According to textures, railway track fishplates can be made of
nodular cast iron, Q235 rolling and forging/blacksmithing. Models
of the fishplates joint can be divided depending on rail weight
such as 8kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg, 38kg, 43kg, 50kg,
60kg,75kg, etc.
Surface requests of railroad fishplates
The fishplate is a connecting link between the preceding and the
following steel rails. Therefore, if the quality of the fishplate
is poor, the caused consequences would be unimaginable. Many
quality inspection rules shall be followed during production,
including surface requests as below:
The fishplate surface should be clean and smooth without any crack,
scarring, scratches or any other defects. The end faces shall not
be with any shrinkage cavity mark or intercalation. The allowed
surface defects and relative geometrical quantity for both light
and heavy rails shall be within the range of standard provisions.
A fishplate of rail track after rolling should be straight without
significant bending or torsion.Assembling and maintenance of fish plates in railway
To ensure the fine use of railway accessories and fittings
including rail splice bars, it is necessary to maintain the
fishplates from time to time, to improve the equipment quality and
avoid any accidents. Assembling and maintenance standards of
railway fish plates are as below:
The fishplates’ assembling device in place without any wounds or
cracks; fish bolts well fixed.
Each connected rod or out-lock device is not found with any wounds
or cracks. No grinding or corrosion on the rod body and abrasion
pin hole less than 1mm with good insulation.
All iron rods’ insulation connection and the insulation link
between out-lock iron and gauge rod are both fine. At uninsulated
condition, 3mm gap shall be kept and not into other parts. Bolts
are fixed well in place as well.
To guarantee none crack is found on the shell of the switch machine
to install fishplates, and the installation is firm under good lock
condition.
To ensure the oil tank circuit in good protected condition without
any damage or being buried by ballasts or other debris.
