- Plasser's Quick Relaying System (PQRS)
It is essentially a semi-mechanised system of track renewal. PQRS consists of self propelled cranes which move on an auxiliary track of 3400 mm gauge having the same centre line as that of track to be relayed. These portal cranes are capable of self loading and unloading from BFRs. PQRS has following components-
i) Side Frames:-The machine contains two vertical side frames that house two vertical sliding frames.
ii) Bridge:- Sliding frames are joined together with horizontal cross frame known as bridge. The Motive Power, hydraulic and electrical assemblies are installed over the bridge. The whole bridge is raised/lowered to facilitate lifting of panels.
iii) Sleeper Gripper:- On the underside of the bridge, grippers to pickup sleepers is provided. Gripping of sleepers by its end is done by two angles welded to the grippers.
iv) Rail Clamps:- On the end side of the frame scissors type clamps are provided to hold the rails/panels.
(v) Turn Table:- To facilitate turning of portal cranes for placing it on the BFR and off tracking in mid section, a turntable is provided. On the BFR a wooden platform is provided to support the turntable.
Earlier, Portal cranes of model PQRS 2000-I has capacity of lifting maximum 5 t load. Maximum length of only 9 meter of prefabricated panel with PRC sleepers can be lifted by one portal crane. The later model PQRS 201 has capacity of lifting upto to 9 t. One such portal crane can lift 13 m long prefabricated panel with PRC sleepers.

Briefly the sequence of operation for relaying with PQRS is as under:
Panels are fabricated with new sleepers and service rails in a Base Depot. These panels are loaded on BFRs in 3 or 4 layers.
The existing rails in track are cut in lengths of 13 m.
Auxiliary track is laid to proper line and level with the new rail panels, if rail renewal is also to be carried out as part of track renewal. Otherwise, service rails are used for making auxiliary track.
PQRS rake is brought to site of relaying after getting proper traffic and OHE block.
Following three methods of laying of new panels are used depending upon site conditions:
- Pulling the PQRS rake
- Pushing the PQRS rake
- Parting the PQRS rake
Portals are unloaded on the Auxiliary track.
Old panels are removed and loaded on PQRS rake, ballast bed is scarified manually and new panels are laid at site by using portal cranes.
Proper ramp is provided at the beginning and at the end of the day's work .

Wow what a engineering Idea Love idea
Thank you! Cheers!
Nice. Infotmative vedeo
Superb engineering,hard work, good good and good work, congrats congrats...
Thanks for the compliment...
This machine is from SER. SQRS 79 &80 simplex manufacturer. I was posted in this machine in my training period
@@shashwatdohare5980 Great job 👍 I think you know Dolai babu.
@@railwayrookie yes
Jay Jagganath bhai.... K
Joy Jagannath 🙏
Wah good
@@tejabhaiaal7266 Thanks
Nice video going on there and like and share thanks DD.
Thanks
@@railwayrookie Thanks very much for replying to my comment. lt's nice to be in this great Community sharing ideas.Take care DD.
Incredible ❤, bhai video achi hai, keep it up.
Thanks for your kind words 🤗
ट्रैक मशीन के जॉब के बारे में बताए
I hope you are asking about Track machine JE/SSE profile.
Kaam bahut acha hai, 21 days at Job location, 7 days rest continuous. Agar manage karte ho to rest days badhega unofficially. During office days, you have to stay in Track Machine staff rest van and will work according to roster hours. You will get huge TA and enough respect for your good work.
In one word, excellent job profile.
Vishwaguru bought this machine on tour to Switzerland. Earlier labourer did all manually.long live Indian railways.
😂😂😂
Ye Simplex ki machine hai 2017-18 ki purchased model hai rajnandgaon me iska plant hai aur ye sab machine 1965 se chal rahi hai bhai
Beta 1980 se h yeh machine..
@@shashwatdohare5980 india me toh manual hi tha kya bakwaas kar raha ...Maine yaha Mumbai me 10 saal track laying dekha hai aaj tak ye machine nahi aayi
On this track what can be the speed of the train is it is same as the before track speed or be 200 kph or 220 kph
It will be capable up to 160kmph in the near future.
Aap retro ki jarurat ho to batana
Ham bhi operating Karte Hain
This type of equipment may be ok for making a siding from the main line but to lay a msinline you need ribbon rail and the more sophisticated equipment to lay that.
Implementation of latest technology is always appreciated. But, here, we do renewal of main line using this same technique efficiently.
@@railwayrookie from what i saw the equipment can't handle ribbon rail so are you saying they don't usr ribbon rails on the new tracks yhey are laying for thr freight corridor
@@rogers906 this is just maintenance equipment.. track laying machine different... that track laying machine use ribbon rails.. and yes DFC has ribbon rails.
Where do u assemble the Sleeper, rail and fastening. How do you load in wagon. Is assembly done at Sleeper plant. Can u show the video pls
The frame comprising rail, sleeper and fastening is assembled in specific plant/ yard or siding. The frame is loaded on wagon by Crane. You are right.
There is a depo where panels are made with the help of a crane named gantry car. That work is totally given to contractor
А чем балласт (щебень) вырезали? Неужели в ручную?
Yes, Wire claw, a small hand tool is used for ballast regularing.
Ya Track War Train Chi Maximum Speed kiti ahe
130 kmph.
Ish me group d wala karna padega hi kya
Dekho, isme jyadatar kaam to agency ka labour log hi karte hai. Abhi Group worker log site protection and safety ko dekhte hai.
Plasser machine ?
PQRS - Plasser Quick Relaying System.
Plasser is manufacturer.
This is similar machine - SQRS, manufactured by Simplex company.
@@railwayrookie simplex is Indian ..isn't it?
@@sriparnoghosh2424 Absolutely 👍
@@railwayrookie great ❤️👍

Yes, a Machine se zada zaldi kam hota hai. Guwahati to Dibrugarh line me Dhansiri Railway Station ka nearest kam ho raha hai. Kisi Contractor ko dekhna hai to akar dekh sekta hai. Bahut zaldi kam hota hai aur Labour kom lagta hai.
@@pareshdas8060 Absolutely right.
