One of the most marvelous and rare KZbin channel about trains

[@TheTrainStory]

Thanks mate 😊

[@i_am_samar]

Seriously very underrated channel, loved the technical part so well explained. Please sir keep adding videos, 🙏🙏🙏

[@TheTrainStory]

Thank you for the kind words

[@christopherbentley7289]

With a personal interest in both the Czech Republic and Slovakia and - to a lesser extent - France, where the rail network is, in all three cases, a mixture of higher-voltage AC and lower-voltage DC the various different 'plus' and 'minus' points about the two systems are of very great interest, so thank you for explaining it all so clearly. I do quite a lot of tracing rail journeys on KZbin in those three countries and it is always quite a challenge to detect whether one is under AC or DC catenary by how heavy the overhead wire looks and how often one sees a transformer station beside the railway...although there is invariably some text that takes that guesswork away!

[@TheTrainStory]

Thank you Chris…

Here in Los Angeles we use 750DC. Love my job as a Traction Power Inspector.

[@ColinBuckowski]

I cannot believe that there are locomotives with the circuitry to run on four distinct power systems. My mind is literally blown. thank you for this video!

[@Vokabre]

Multi-system locomotives or EMUs are probably the best solution in the long run when there are multiple systems in use, making expanding the routes and redirecting rolling stock from one route to another much easier.

[@TheTrainStory]

Yes particularly for multi-country routes

Nice explained DC & AC Electric ELECTRIC Locos 👌🔥

[@someshwarroy52]

Again thanks for a detailed presentation in subtle language, eagerly waiting for another such, this time preferably on evolution of signalling system in Indian railways

[@TheTrainStory]

Thanks for appreciating. I have discussed signaling here (kzbin.info/www/bejne/nn2QiKqcp92tsMU and kzbin.info/www/bejne/q6qronyui99krNU).

[@SRINIVASREDDYMSRAILCLICKS]

Thank you for clearing my doubt on 3 phase motors

[@charlesbeck6436]

Electric railways are not necessarily non-polluting if the power plant producing the electricity they use is produced at the power plant by coal, natural gas, or nuclear power. The only way that electric railways can be non-polluting is if the electricity needed to power them is produced by wind, solar, or tidal means. Any other way just shifts the pollution from the individual engine to the power plant that supplies the power.

[@TheTrainStory]

Unfortunately Yes…

[@nicolaskarmitz1458]

Well yes, it is not 'non polluting', even considering the building of the trains and track and stations. But it is muuuuch more efficient than other transportation methods due to the electric motors and frictionless (frictionlow) movement. Walking or taking a bike is also polluting in that sense.

[@RAMKUMARRAM-dq4pm]

I have a question and didnt get answer for it after watching this video, single phase 25kV line used here and neutral is grounded through wheel and railway track, now my question is what ever is the amount of current flowing from 25KV phase goes to neutral (ground), how the circuit is completed here, and what about the losses when the neutral is grounded? Please answer

[@TheTheo58]

My home state N.Calif SF/Bay Area has a heavy rail transit system BART serving four counties some 120 + miles of track. The trains are powered via 3rd rail 1Kv DC each station stop or close by has a power substation with DC power houses. The original traction motors were DC, 500V wired in series each car had four motors. In the late 1990's a changeover was made to 3 phase traction motors along with a 3 phase inverter.

[@ArghyadeepPal]

Your channel is really awesome bro. My love for trains rekindled when I played the game Transport Fever 2.

[@TheTrainStory]

Thanks friend 😊

[@trueindian887]

Very informative.pl compare AC and DC Traction motors in terms of speed control,starting torque, coling requirements and maintenance like brushes etc

[@udaykrish6735]

What an explanation sir....... marvelous..... We need detailed videos for evry Indian loco.

[@TheTrainStory]

Thank you friend 😊

[@johnrieley1404]

Excellent explanation with good video footage. I would think the multiple voltages propulsion systems design and maintenance keep the electrical engineers at full employment.

[@gopalshekar986]

Nice video👌 However, at 1:46 - while explaining DC traction systems - "..3 phase power , received from the power grids.." - are we refering to traction motor control system here?

[@shirishpurohit9449]

Nice video, thanks. Key DC / AC differences hard to find somewhere else. Helped a lot :)

[@binaryglitch64]

I'm a residential electrician, and I'm just trying to understand what my local light-rail system uses as the return path as we only have one cantonary wire and no charged rail... so what gives, how is the circuit completed?

[@arjunsridhar5974]

Awesome videos with animations and explanations 😊

[@TheTrainStory]

Thank you

[@cutieandcookies211]

Question: Why do I see some diesel locomotive/multiple units also having AC/DC traction motors? Are they different from electric locos/EMUs?

[@TheTrainStory]

Those are diesel-electric locomotives/multiple units. A Diesel engine drives an alternator that powers the traction motors. The difference is, a diesel-electric loco carries its power supply onboard while an electric locomotive draws power from overhead or third rail catenary.

[@deathgamer5606]

Thanks for clearing my doubt sir! Superb animation!!!

[@TheTrainStory]

Happy to know 😊

[@kgiplmdrf9488]

Dc system is rigid but the motor are head ache and we can't accurately control dc motor speed, while ac motor speed can controlled very accurately using vvvfd but due to Indian quality of manufacturing these days the convertor and controller fail often ( especially the medha ones)

How did you do animation can you please tell me which type of software you are using for making this train

[@TheTrainStory]

I generally use a combination of photoshop and premiere

[@carl-gunnarhillefors7612]

MOST OF EUROPE USE 15kV 16 2/3 Hz AC when it's near DC. To increase speed the had a transformer with many windings a fed the DC motor WITH NEAR DC CURRENT in the locomotive. Today use of ASYNCRON MOTORS AND USE THREE PHASE TYRISTOR REGULATED AC TO INCREASE OR DECREASE SPEED!

What happen if DJ not tripped while negotiating NEUTRAL SECTION.

[@livestocknetwork320]

AC has too many disadvantages; it doesn't work well in hilly areas and tunnels; more electricity is wasted and there seem to be too many problems in bad weather. DC third/4th rail seems to be the better alternative...

👍 why dc locos won't cross cr zone bro

[@TheTrainStory]

DC locomotives are now extinct in India. Earlier the Mumbai region was the only area with DC (1500 V) supply, therefore DC locos were restricted to Mumbai only.

[@saikarthik261]

@@TheTrainStory but those wcam will support both ac and dc know bro so they can run other States or zones no

[@TheTrainStory]

Because of absence of sheds. Presently all WCAMS are homed in Kalyan shed (I am not sure about Valsad). Therefore the locomotives are rostered within the serviceability range of Kalyan shed. Although technically, the WCAMs can run on all electrified sections of IR.
