While in previous publications the catenary system had been presented one or the other was wandering why and what are the benefits of third rail power supply systems - please find enclosed a respective description

Railway electrification systems can be categorized based on the method of power supply and voltage levels. The two main types of electrification systems are: 1. Overhead Line System (Catenary System) 🙂 This system uses overhead wires suspended from structures (masts or poles) to supply electricity to trains equipped with pantographs that draw power from the wires. Common Voltages: 25 kV AC (Most common in modern railways) 15 kV AC (Used in some regions, such as parts of Europe) 3 kV DC (Used in several areas including urban rapid transit and some mainline services) 2. Third Rail System 🙂 In this system, an additional rail, known as the third rail, is laid alongside the two main tracks, supplying electricity through contact shoes on the train. Common Voltages: 600 V DC (Commonly used in urban transit systems) 750 V DC (Also used for metro systems and light rail) 1.5 kV DC (Less common but still in use in some regions) Other Systems Hybrid Systems: Some modern trains can operate using both electric power (from overhead or third rail) and diesel power, allowing them to run on non-electrified tracks. Battery Electric Systems: Emerging technologies are exploring battery-operated trains, where batteries on board provide power without needing constant electrical infrastructure. #monenco #railway #electrification #system #catenary #contact #wire #dropper #pole #bracket #tube #register #arm #insulator

* UPLIFTMENT (026) * Part 7 "Disadvantages Of The Maglev Trains: 1) Maglev trains are much more expensive to build compared to the Conventional trains 2) They cannot use existing infrastructure, New ones have to be built which also involves a high cost 3) They use up more energy at high speeds more than Conventional trains 4) Electrodynamic Suspension (EDS) Maglev Trains naturally create a field in the track in front and to the rear of the lift magnets, Which tends to act against the magnets and create a magnetic drag at low speeds 5) The separation between the vehicle and the guide way in EMS Maglev trains must be constantly monitored and corrected by outside systems due to the unstable nature of Electromagnetic attraction may induce vibration 6) The strong magnetic fields on the EDS Maglev trains make the trains unsafe for passengers with Pacemakers or Magnetic data storage media such as Hard drives and Credit cards, Making it necessary to use Magnetic shielding, Limitations on guide way inductivity limit maximum speed 7) Alot of the train's energy is consumed just by overcoming AIR DRAG FORCE (AIR RESISTANCE) of opposition on the train as it's in motion 8) In EMS Maglev train if the power of the system cuts off this will shut down the system 9) When developing a Maglev train system a new infrastructure that cannot be integrated with existing rail roads will be built, This will compete with existing High ways, Rail roads and Air routes 10) Maglev train system is very expensive to build 11) They require the use of Rare-Earth elements such as Scandium, Yltrium and 15 Lanthanides) which would be very expensive to recover and refine, And these Rare-Earth elements are used to make the Superconducting magnets that tend to levitate and propel the train forward on the guide way 12) Maglev train needs a significant amount of power or energy for (Intial acceleration) for it to start moving from rest 13) Since Maglev train's tracks are only located at few routes, That is why the Maglev trains are not yet widely used globally unlike the Conventional trains, Thereby limiting the utility (use) of the Maglev trains in different places around the world 14) Building a Maglev train system is very expensive due to it's specialized tracks (guide way) and technology required 15) Maglev train's guide ways are not compatible with existing rail infrastructure, So any organization attempting to implement a Maglev train system must start from scratch and build a completely new set of tracks and it definitely involves a very high initial investment" Write Up: Joy Obor Video Credit:This is from the social media and all Credit goes to the owner of the video FOLLOW 👉Joy Obor for Inspiring and Motivational Posts everyday Greetings from all of us here at "SPRING BOARD MEDIA" God bless us all 🙏
