Metro Kaise Chalti Hai?

Kya aapne kabhi socha hai ki roz lakhon logon ko ek jagah se dusri jagah le jaane wali Metro Train bina kisi fuel (diesel/petrol) ke, sirf ek wire ke sahare itni fast kaise chalti hai? Is video me hum Metro Trains ki shandaar engineering aur science ko bilkul aasan Hinglish me samjhenge. Hum jaanenge ki kaise 19th-century ki underground railways ek "smoke hell" (dhuan aur ghutan) ban chuki thi aur kaise uske baad clean electric traction ka janam hua. Sath hi, hum dekhenge ki Overhead Catenary System (Pantograph, carbon strip aur zig-zag wires ka secret) aur Third Rail System kaise kaam karte hain. Aur sabse zaroori—video ke end me hum discuss karenge ek aisi life-saving safety warning jo aapki jaan bacha sakti hai, kyunki metro ka high-voltage current bina touch kiye bhi aapko khinch sakta hai!
