Indian Railways Thread (Dec 2015)
Re: Indian Railways Thread (Dec 2015)
for the exterior they could have taken help of wind tunnel facilities and aero depts in one of the IIT, or HAL for its wind tunnel and got a much more refined product with proper fluid dynamic analysis.
this looks like just rough n tough hack job going by visual looks.
even for a car, if the windows are open it increases drag by 4% .... conformal lights, horns, flush windows as seen in proper HSR locos is what we need.
this was low hanging fruit ... has it even been tested pulling a train at 200kmph or its "gut feel" it will magically manage 200kmph

Re: Indian Railways Thread (Dec 2015)
Trust me, IR does some rudimentary wind tunnel analysis of its locomotives. I've seen WT models of WAP-4 & WAP-7 (not the above loco). Was surprised and pleased to see those WT models. I am sure they would have done some CFD analysis on the modified locomotive to rough out the edges in design...what is shoddy is the execution/manufacturing of the model. One can see dents in some of the sheetmetal bends.
WAP5 was always capable of doing 200Kph. What it needed was changes in software & loco gear ratios for higher speed operations.
Per one of the RDSO documents on WAP5 (modification of the loco to make it suitable for 200Kph operation & also twin loco config),

India keen to locally manufacture and export bullet train coaches

Size of the Indian market itself is huge if the trainsets are affordable enough. They should be the ones going all out to propose this to us.He said that the Modern Coach Factory, Raebareli in Uttar Pradesh is well equipped to produce the coaches.
"Add to this around 150,000 skilled workers, 50 railway workshops and around six production units that railway has at it's disposal," Agarwal said.
The Ambassador of Japan to India Kenji Hiramatsu said that the discussions over manufacturing the Shinkansen coaches locally were going on.
"The discussions on this is going on. I believe it's best to manufacture locally and we are seriously thinking about it," he told this reporter.
If the move works out, it will also open a new business opportunity for the state owned organisation which is reeling under high operating costs.
The scope for high speed railways across the globe has huge potential. It is currently in different stages in the USA, Vietnam, Malaysia, Singapore, Thailand and Indonesia.
"The idea is to get Japan to produce not just the rolling stock for railways in India but also other sectors like defence using our manufacturing units. That will be a big takeaway," said Agarwal.

Why is train-18 being hauled by an engine?
Re: Indian Railways Thread (Dec 2015)
It's standard IR practice for un-commissioned equipment. This is just the "ferry flight" equivalent on rails, much testing awaits.

Re: Indian Railways Thread (Dec 2015)
Minor nitpick - that is a locomotive and not an engine. There is a big difference in the meaning of locomotive and engine.SBajwa wrote:Why is train-18 being hauled by an engine?
regarding why it is hauled by a loco, the answer is because it is not tested for mainline tracks. One can't send an untested train on its own via a congested corridor, without the support of a locomotive.
Re: Indian Railways Thread (Dec 2015)
It is been transferred to Delhi. Needless to say the tracks all the way to Delhi is not electrified. So Train-18 cannot go by itself to Delhi.
Re: Indian Railways Thread (Dec 2015)
^^ Eh? Did they pull out all the traction poles in this route?
The Chennai -Delhi route has been fully electrified since the early nineties.

Lessons learnt from Train 18 being applied else where by ICF.
Re: Indian Railways Thread (Dec 2015)
The Japanese (thankfully) take immense pride in some of their achievements & culture. And Japan is also a very small country, and pretty much has a uniform culture. Perhaps all these add to the unique running aspects of Shinkansen. Such a system would take 100s of years to come to India.Singha wrote:how ever in terms of tight discipline, looks, dress, precision and general stds nothing comes close to the shinkansens on home ground! there are pretenders but the original is still the best.
My first onsite posting was to a city in Japan, but I did not get an opportunity to travel in the bullet trains. I could only see them fly past some of the stations. Even their normal trains generally stick to their time tables. I had to make a trip to another city, and taking the help of a Japanese colleague got the time table worked out. I had to change trains at two points and as per the time table connections were available within minutes of my arrival at each point. The local time tables are generally only available in Japanese.
But on the day of arrival, heavy winds in some areas forced the trains to reduce the speeds. And this messed up the time tables (and my schedules) as well. My first train itself arrived 15 mins late, and on a different platform. I had to figure out connection trains at the two intermediate places. It was only the basic Indian quality - "Ask & Proceed" which helped me here. The staff were off course helpful, and in the local trains I was a character of interest . I also saw the Japanese technique of "Point & say" diligently followed by the JR staff (it looked a bit comical then, but later understanding the process better I could appreciate that).

https://www.news18.com/news/india/train ... 41673.htmlTrain 18, India's First Engine-less Train, to Go on Trial Run in UP Today; Will Head to Rajasthan Next
High-speed trials will be conducted between Kota and Sawai Modhopur after the Moradabad trials. Train 18 is capable of touching 200 kmph provided that the rest of Indian Railways' system such as tracks and signals permit, Mani said.

Chennai: Vested interests are trying to "fail" India's first locomotive- less train or Train 18, a top official said on Friday, adding there was nothing to worry about the glitches that occurred during a trial run.
"During the low speed trials of Train 18, a power disarray was noticed - technically called harmonics - which led to blowing up of fuses and activation of safety (systems) at (electricity) sub-stations and stalling of some locomotives in the section," S. Mani, General Manager of Integral Coach Factory (ICF) that has manufactured the train, told IANS.
Mani said after the problem was resolved, "the locomotives were promptly put back into service, the sub-stations were attended to and feedback was given to the ICF".
He said the onboard software for traction and regenerative braking were also tuned to eliminate harmonics.
"This was all done within a day of reporting."
On October 29, the Rs 100 crore indigenously developed high-tech, energy-efficient, self-propelled or engine-less train was flagged off here by Railway Board Chairman Ashwani Lohani.
The train was later put through lowspeed trials to test its various systems.
"The train underwent the low-speed trials between ICF (Anna Nagar station) and Villivakkam, a distance of 1 km. Such a short distance does not permit higher speed build-up. However, many important systems were tested such as operations of brakes, interaction of the pantograph with overhead wire, familiarity of driver controls and high voltage tests to the extent possible at a speed limit of 30 kmph," Mani said.
"The current certificate is valid only for Moradabad-Bareilly and Kota-Sawai Madhopur sections. However, during its travel from Chennai to Delhi at full sectional speed all its mechanical systems such as wheels, springs, pneumatic suspension and pneumatic brakes as well as its dynamics proved themselves satisfactory," Mani added.
Talking about the speed trials, Mani said medium speed trial of Train 18 will be conducted between Moradabad and Bareilly over the next few weeks.
"Vast instrumentation has been provided on the train by Research Design and Standards Organisation (RDSO) for this purpose. These tests will certify that Train 18 is fit on all tracks of Indian Railways at a speed of 110 kmph," Mani remarked.
High-speed trials will be conducted between Kota and Sawai Modhopur after the Moradabad trials.

Re: Indian Railways Thread (Dec 2015)
I don't understand this. The Train 18, at least in the initial phase, is supposed to replace the existing Shatabdi type inter city express trains. Most of them have one or two stops at the most. So the advantage of faster acceleration can only be marginal at best. Of course if the advantage is over all higher speed due to light weight material etc. then it is something else. Right now it is only a technology demonstrator I suppose. Does it offer superior economies of operation?
Re: Indian Railways Thread (Dec 2015)
faster acceleration while it gains more from real stops, but I dont think rest of time it can steadily cruise at its top speed despite rajdhani/shatabdi being given line clear and all other trains pushed to sidings - there are speed limited sections and old bridges that need due care. human and cattle movement areas = in all these, anything that gets back faster to top speed will benefit.

Make in India Success: India’s First Engineless Train Is 23 Per Cent Faster Than Shatabdi, Completes First Trial
A view of the Train 18 at Safdarjung station, during its trial run, on November 14, 2018 in New Delhi, India.
India’s first engine-less train had its first trial run of the on the Bareilly-Moradabad section, reports Metro Rail News. Train 18, believed to be the successor to the Shatabdi Express is developed at the Integral Coach Factory (ICF), Chennai.
The Train 18 designed to model the bullet trains, was unveiled by the Chairman of Railway Board, Ashwani Lohani, last month.
The T-18 was built under the current government’s ‘Make in India’ initiative within a span of 18 months.
The fully air conditioned train has a self-propulsion module which can reach a speed of 160 kmph as opposed to upper limit of 130 kmph for Shatabdi and includes technical features for enhanced quick acceleration. As compared to Shatabdi, it will cut the travel time by 15 per cent.
It cost Rs. 100 crore to build the first long-distance train which does not feature a separate locomotive or engine.
As reported earlier the train, had a few short runs in Chennai. The trial runs saw a few glitches and issues. However, the Indian Railways said that such minor issues were routine in the trial phase. A railway official said, “Some fuses went off while conducting the low-speed run in the city (Chennai). They were fixed immediately. There was nothing to worry about,” as quoted by PTI.
Train 18, or T-18, is named as such because was built in 2018. The 16 coach train will have various modern features. The train is completely computerised and has diffused lighting, automatic doors and footsteps besides GPS-based Passenger Information System.
It will have its final test run at the speed of 160 km/hr at the Kota-Sawai Madhopur stretch. The train is expected to begin its services by February 2019.
Re: Indian Railways Thread (Dec 2015)
Next step should be to modify existing tracks where T 18 can hit 200kmph.

Re: Indian Railways Thread (Dec 2015)
the Talgo managed to take 2 hrs off the august kranti rajdhani record. hauled by a loco but smaller and lighter than LHG coaches.
it must have stopped at some points to change engines and drivers. our aluminium metro trains are also able to speed up rapidly.
train20 should be targeted to sleeper bogies and replace the LHB/ICF sleepers enmasse.

Re: Indian Railways Thread (Dec 2015)
This trial was carried out only at 110 kmph. It will be tested upto 160 kmph. But using this train all over will need more investments in track and signalling.

For the sleeper cars, IR's problem is two fold
IMO a DD train set with some clever design can be of our use here. I was very surprised to find next to nil design ideas on this front from desis.
Only one I could find who is also thinking on my line but his ideas were just limited to 1AC

Here is one example from Russia who have made it to 2T concepts, but we need to extend it till 3T for our use case

I am trying to draw some rudimentary ideas, then again CAD is not my cup of tea.
