How Many Holes on Rail Tie Plate
Rail tie plates are crucial components in railway track systems, and their design varies based on the specific requirements of the track and sleeper types. One significant aspect of tie plates is the number and shape of the holes they feature. Typically, rail tie plates come with square, round, or elliptical holes, each serving specific purposes:
Square Holes: These are commonly paired with dog spikes and used on wooden sleepers. The square shape provides stability and prevents rotation of the spike, ensuring secure fastening to the sleeper.
Round Holes: Round holes are often matched with screw spikes and used on prestressed concrete (PSC) sleepers. The circular shape allows for easy insertion and rotation of the screw spike, facilitating a secure attachment to the sleeper.
Elliptical Holes: Similar to round holes, elliptical holes are also used with screw spikes on PSC sleepers. The elongated shape offers flexibility in positioning the screw spike, accommodating variations in sleeper dimensions and ensuring a secure fit.
