Is it possible to run LHB Intercities with Non-AC Coaches safely at 200kmph (if we have upgraded tracks for 200kmph and a loco that hauls 24 coach train at 200kmph) without facing air drag and train being lifted?

It is an extremely severe cyclone, with energy outputs equivalent to a category 5 hurricane.

Speeds of 175 KMPH come under a Category 2 cyclone. Category 5 are more frequent in the Atlantic Ocean as the ocean is known for its violent nature. That being said, as per my knowledge, I've never seen such high speed cyclones in India. Intensity is due to warm water that evaporates and intensifies the cyclone. Warm climate is a factor, adding to that are climate change and Global warming.

The train won't be lifted. Technically, if you loco has the capability to haul that load at 200kmph and if the coaches are fit, then they can be run at 200kmph. But that's the the problem here. The problem is with the passengers.

At 200kmph, the effect of the wind is going to be very severe. A passenger sitting at the window with that wind constantly blowing on their face can sustain health issues. Having high speed wind slamming into your nostrils is not good.

The noise is going to be extreme. Even at 60-80kmph, the noise at the windows is very noticeable. At 200kmph, it will be enough to cause extreme discomfort.

Most importantly, the air drag is going to increase the power consumption of the locomotive. The energy costs will increase by a big amount compared to running the train at lower speeds.

So, can they run non-AC trains at 200 kmph? Probably.
Should they run non-AC trains at 200 kmph? No, they shouldn't.

    These days, every other day, we are getting requests from members to allow email login to their FB-based IRI account. 10 years ago, we had given the option for users to login through FaceBook - in retrospect, this was a mistake. These days, apparently, users are quitting FaceBook in droves because...
