Study Notes

Agulles are used to switch trains from one track to another
The two needles must move together to establish a route
They are connected by a tie rod
Counter-needles are formed by rails where the needles are adjusted
The intersection of the two tracks is called the cor
There is a gap called the llacuna to allow the wheels to pass through
The llacuna prevents the wheels from having to go over the rails
The wheels pass through the llacuna while crossing the intersection
The text describes the parts of a train track intersection
The text explains how the parts of the intersection work together.
Friction between train wheels and rails causes high wear and tear
Lubricant layer is used to reduce this effect
Greasers are devices that apply lubricant to rails through pedals activated by train wheels
Pedals can be mechanical or electromagnetic
Mechanical pedals are commonly used
Lubricant is taken from a reservoir and pumped onto rails through nozzles
Greasers help reduce maintenance costs of trains and rails
Lubrication also improves train performance and energy efficiency
Different types of lubricants can be used depending on weather conditions
Proper lubrication is crucial for safe and efficient train operation.
Pedals are installed along train tracks.
They can be mechanical or electromagnetic.
They generate an electric signal when activated.
This signal can be used to control various installations.
Examples include level crossing barriers and automatic doors.
The signal can also be used to regulate train traffic.
The pedals are activated by the weight of passing trains.
Mechanical pedals are activated by physical contact.
Electromagnetic pedals are activated by changes in magnetic fields.
The pedals provide information about the location of trains.
