No one is wearing safety gloves and still manual work is required. No automatic instruments for unscrewing the nut and bolt... Railway has to modernise for maintenance jobs of locomotive....
This is surely an easier way of dealing with a locked axle condition. However, would this work seamlessly given that axle's load is no more equally distributed between the remained axles? Doesn't this risk overheating the journal bearings or even stressing the track/infrastructure?
I would guess it is used just to limp it into the main shop where it is going to be properly fixed. So to just get it moving, even when with restrictions like limited speed or so... By the way the 30% extra weight is by far not that much of a loading on the other axles, as is the fact they effectively deleted all the suspension, the two working axles are holding the frame via hard steel lifting inserts, so any uneven spots and the dynamic loading will become not 30% bigger, but 3x bigger than normal at the same speed.
If the loco is not used for hauling trains, not used at higher speeds than a crawling speed, it is okay. The next trip for the loco is to crawl to the maintenance shop anyway.
Since middle axel has got locked and the engine MAINTENANCE SHED IS FAR AWAY ,so this is the most easiest, smartest and beautiful way to take the engine to the MAINTENANCE shed and train can also complete it's duty.
💥 Indian railway engine... Wawoo look what a neat & clean engine.. Build quality is in international.. Super ... Railway thinking like that ... But its true..? Why railway not giving important for neat, clean and finishing works..? 2024 we are still like this? Shame.. 💥
This also happened when I was in Bangalore railway station several years back, just to take some videos. Brindavan Express was crawling into SBC, but stopped halfway into the platform. So I walked up to the loco, which was a WAP-7, and they said the wheels had locked up and started ‘cutting’ (don’t know what they meant). After several minutes the train crawled very slowly to reach the end of the platform, where the service people started milling around the loco to fix the issue. I didn’t stick around to see what they’d do.
Why are they not using blocks to stop accidental rolling are the brakes in locked position? I also wonder how did they diagnose which wheel is in locked condition? is it because of heat on the wheel or any real time monitoring exists via thermo couple or infrared scanner non contact? Or is it via rpm differential with respect to other wheel / axels? Anybody please thanks in advance!
Why are they not using ratchet after initial release with regular wrench . We are eons away from increasing productivity reducing down time also using torque wrench with preset torque setting is better way . Om I stand corrected they did use a ratchet . But there is enough space to use box socket instead of open wrench which can damage the hex nut. Also the have pneumatic jack or could be hydraulic then why not use compressed air tools. If you don’t have access to 240 volts power point to drive a compressor for tools one can use compressed air tank. Even better tap into the compressed air tank of loco which is used to actuate the brakes… well from a Mechanical engineer with 40:years experience in machine tools service in the field and commissioning huge machines .

They are reducing the axle load on the middle axle of each bogie, which will increase the axle load on the remaining two axles. This will make these Co-Co bogies act like Bo-Bo bogies, which will improve acceleration and maximum speed at the cost of adhesion and number of wagons hauled.
@@pmaitrasm Thought they were just lifting the middle locked wheel set so loco can be moved to maintenance facilities , we do similar by placing wheel skate under locked wheel skate . Loco would only be allowed to move short distance at very reduced speed with middle axle lifted as remaining wheels would be exceeding maximum axle weights
@@nounoufriend1442, You are right about locked wheel. However, I saw that all the axles were rotating. Not sure what happened. Removing two axles from six axles will be fine if the rails are heavy enough. Also, I wonder why they have provided the shackle link only for the middle axle.
You have a valid point though but it has to be enforced by rule when its not followed by will. And for this it has to come top down. Coming here and complaining and mocking does not help. And throwing the country under the bus also does not make sense either. You want to make a change? Write to Ashwini vaishnav in his X or other handles, give the suggestion that safety has to be prioritized for railway workers. He is a smart chap and listens - so write there in his X or other handles instead of venting here.
Bhai inhe safet device safety gloves sab kuch milta hai par pahan ne ki adat nhi hoti. Indians neglect safety. Ab bike ka hi example le lo, helmet sabke pas hota hai par agar fine lena band kr diya jaye to 90% log helmet nhi pahnenge
No safety protocol seems to be present, neither in the form of any safety inspector or safety equipment. All caution seems to be out in the wind. Would like to know what is the rate of injuries of technical staff in the Indian railways. Is there anything called safety protocol present in terms of equipment, personal safety and so on. The use of mechanical tools is primitive, there is very little use of power tools. This is shameful for the Indian railways, and now the bullet train.
Having worked on breakdown (derailment ) team many years in UK I was quite impressed with this method of dealing with locked wheel set , we always used wheel skate , far more risky ie having to assemble it under wheels set . I would think using power tools would entail more risk but lifting gear "jacks ect " looked decent . I'm assuming they have stopped lines either side , but the lack of Hi viz is an unnecessary risk

I suspect this is a 'Get-you-home' lash-up, to enable recovery and return to repair shop. I very much doubt the loco will return to service with the lash-up fitted, as they have placed travel-limiting blocks above the bogie end bearings to prevent excess load damaging the springs and brake-gear.
@@nlo114 Suspect the other wheel sets will be sat on the blocks once off the jacks so relying on bogie secondary suspension between bogie and body , then a very slow trip to maintenance depo . Neat way of doing this as we would have used a wheel skate and these are problematic over points ect due to small wheels
Wearing of gloves is not necessary as the work is done on the periphery of the loco and no heavy part is being moved/lifted. Someone mentioned use of pneumatic tools, . That's not required as the work does not involve major fastening.
@@vara1499gloves should be mandatory, it’s about worker safety policy. Also power tools are required, workers can get repetitive strain injury. You should learn from western countries, about worker safety and repetitive strain injuries.
This is som scetchy $hit, almost as scetchy aas cutting off the lower half of the wheel, which is what one of the private rail companies did here in norway, with an acetylene torch😂.
खूप छान माहिती सर, आपल्या या व्हिडीओ चा इतरांना पण फायदा होईल 👌👍
Seems to be an fair solution to prevent any more damage happen by blocked parts.
Thanks for shareing this video.
Superb,
I think the technical expertise of Indian railways is the best.
Keep up the good work.
you are funny
indians and superlatives.A match made in heaven
These guys are experienced and try out various ways to solve. Indian Railways is a great wonder.👏🙏

the money would have already allotted and taken for gloves and instruments. But someone swallowed it.
Everything is provided but no one uses it bcz they are comfortable with their own way
Everything is provided bro. It's just that these people don't use it becuase during warm and hot weather, the hands of become sweaty
Why not, so many torque wrenches available for loosening /tightening the bolts and hydraulic modernised heavy duty screw jack also available.

super great video sir ❤❤😍😍
Engineers and Technicians should have wear the Helmet and hand gloves for the safety only. 👍👍😊
Wow probably the world's first lift axle locomotive
Safety Measures ? OR doing this work in more safer way ??
Ok I see a tube from the axel which could be the transducer communication with the bearing axel combination?
