250 km is considered bullet train. Our best brains at IITs can design a very safe bullet train and make it cheap too.

Bullet trains form half of China's train services - Economic Times
Bullet trains form half of China's train services
BEIJING: High-speed bullet trains now make up more than half of China's rail services, highlighting the massive expansion by the government to improve connectivity.
The state-owned rail operator, China Railway Corp, which introduced a new service schedule to meet the booming demand from the public said, of the total 4,894 trains being operated in the country 2,660 were high-speed bullet trains running at speeds of more than 200 km per hour.
"The fact that China Railway Corp adjusts its operation plan every six months shows that the nation's rail network is expanding at an unprecedented speed," Zhu Jianping, deputy head of the bureau told state-run China Daily.
"Compared with the past, now almost all of the major parts used on our bullet trains are developed and manufactured by Chinese engineers," said Ji Jialun, a railway expert at Beijing Jiaotong University.
Analysts, however, are of the opinion that security must be a top priority.
"Railway operators and authorities must pay more attention to the operational safety as they continue boosting the rail network," said Xu Guangjian, deputy dean of the School of Public Administration and Policy at Renmin University.
"In the near future, a bullet train will travel from the ultra cold northeastern provinces to eastern coastal regions that have warm and wet weather, which will pose a huge challenge to planning, maintenance and control personnel," he said.
He said the daily transport capacity of high-speed lines would be increased by 70,000 travellers, 3.8 per cent higher than in the past.
The Beijing-Shanghai high-speed railway, the busiest route in China, has transported 220 million passengers in the past three years, largely due to the high-speed service.
China has the longest high-speed railway network in the world with more than 10,000 km in operation and the country is actively promoting this technology to other countries, including Turkey, Thailand and the UK.
Indian trains can run at 300 kmph: expert
Indian trains can run at 300 kmph: expert
BY DANFES, AGENCY
Given a free hand, Indian engineers are capable of making Indian trains run at 300 kmph, a renowned expert says.
But the railways must shed its archaic mindset to make this possible, B. Rajaram, a former managing director of Konkan Railway, told IANS.
"Our young engineers are quite capable of operating faster trains safely and efficiently, given the political will and a free hand," Rajaram said in an interview from Herndon in the US.
"Trust them to work out the nitty-gritty of doubling average speeds, or making 300 kmph trains a reality on separate corridors, without copying European or Chinese models," added Rajaram, who divides his time between India and the US.
Rajaram had created history of sorts by delivering higher speeds at lower costs with indigenous know-how and existing infrastructure rather than wait for prohibitively-priced imported technology to do the job.
"A trial run which I conducted successfully between Madgaon (Goa) and Roha (near Mumbai) in 2003 averaged 150 kmph continuously over a 400 km stretch, the longest in rail history then," Rajaram recalled.
"The train slashed travel time to a mere three-and-a-half hours, from the nearly nine hours that superfast trains normally take to complete the 442-km journey.
"On a particular stretch, the General Electric-designed diesel loco effortlessly touched 179 kmph until I asked the driver to slow down," said Rajaram, who rode with the driver.
"During the trial run on Konkan route, built for a peak speed of 160 km, I also successfully tested cab signalling for the first time in India."
Cab signalling is what makes the ultra high-speed rail systems in Japan, France and Germany operate so successfully and safely.
"I obtained the cab signal as an additional layer to test whether it correctly replicated the fixed signal functions so that the ACD (Anti-Collision Device) could automatically control speed," said Rajaram.
The entire exercise, involving what the media described as "India's first bullet train", overcame insurmountable barriers that bedevil railway operations, thanks to an out-of-the-box approach and the ACD.
Had the railway ministry permitted the train to operate, it would have paved the way for cab signalling and what is known as moving block, Rajaram told IANS.
Cab signals eliminate the necessity of fixed signals, keeping the driver directly updated about the condition of the track ahead, thus minimizing human error and accidents.
A moving block facilitates the simultaneous movement of two or more trains between two stations even on a single track, substantially cutting down on delays.
It does so by maintaining a safe braking distance (one to two kilometers) between each of the trains.
"It is like driving a car. You control the speed based on the car ahead and distance available to stop if needed," said Rajaram, who helped build the Konkan Railway from scratch as its chief project engineer.
A fixed block, on the other hand, permits only one train on a single track route between two stations, often holding up the movement of traffic for hours. It is an archaic system.
Cab signalling and moving blocks, hitched to an advanced version of ACD, could have been instrumental in facilitating speeds between 160 and 180 kmph for passenger trains, besides raising the average speeds of freight trains.
"Then, no waiting is required for (fixed) signals, occasions for sudden deceleration and acceleration fall tremendously, improving average speeds, while reducing operating costs," said Rajaram.
"These measures, collectively, would cost less than a third of the imported alternatives. We already have the requisite rolling stock technology for 160 kmph speeds, validated by trials on the Konkan route."
The ACD, certified by Britain's Lloyd's Register Rail and the railway ministry's Research Design Standards Organisation (RDSO), is a low cost, indigenous artificial intelligence system Rajaram designed and developed.
It is credited with a 99.9 percent success rate in preventing collisions after commissioning by the Northeast Frontier Railway and Konkan Railway.
Rajaram pointed out that archaic rules and delivery of services were big hurdles in modernising the railways. They need to be reformed using railway WiFi intranet and affordable tablets.

Answer is simple .. "NO" we cannot do that in next 5 years!!
Answer hidden in your post ... auther said we can do it but ....followed by lots of ifs.
Do we have brains - Yes
Do we have capability - No (now)
Can we develop - Yes
Can we do in next 5 years and surpass China - NO
Running a train for 300 km/ hr for short sprint is easy we can do it today if needed. Can we sustain it? definitely no..we need to redesign tracks , engines, signal system, smart fencing, and every nut bolts, raw material ... it would need major revolution with a cargo train full of money.
As of today we do not have industrial base, eco-system, technical expertise. To put all these together with foreign collaboration will take more than 5 years... if we do want to do it our own it will take more than decade .
China has very good example it took them more than a decade ..starting with foreign collaboration, hired and out sourced to right people, observed closely and developed there own based on systems/ know how received from experts. It may be surprising if you find few expats employed in railway industry in China ....we Indians too proud to do that
.
India cannot develop Train lines like china , Land Acquisition is a big problem in India, unlike china which can bulldoze and build new lines in no time , in India lengthy court process and legislation and NGO's can derail any development .

For every Indian who says India cannot, there are thousands who say India can. People like you give sundry excuses just to impede progress. You sound like a Kangress neta.
We are more than 6 years away. It's doable. We have the brains, the money, and Modi-ji has the vision and the leadership.

What is your agenda here? I seriously doubt that you are even Indian.

Indian Railways are very advanced for a developing country. The trains are not bullet but they run very fast. We are more than half way to surpassing China. Modi-ji will make Indian Railways better than Chinese railways by 2020!

Modi-ji will give rebirth to Indian Railways. We are only a few years away from surpassing China!
The Kangress supporters want to see India forever stuck like this:
My agent is for India to surpass China under Modi-ji!
India is a great country, a great power, will be a superpower by 2020!
India will have more advanced bullet trains than China by 2020.
