Under the Shadow of Covid: Train Journeys Across India


Paravur Kayal (lagoon), Kerala


Has the Covid Pandemic changed the way Indians travel? What has been the impact of the cascade of lockdowns  imposed across the country since March 2020?

An opportunity to seek answers to these questions presented itself a few weeks ago. A bunch of old friends had planned a get-together in Krishnagiri district of Tamil Nadu and it had been nearly two years since I met my folks in Kerala. So at short notice, I decided to travel across the country to these two states in the cheapest way possible: Second-Class Sleeper on the Indian Railways.

Thanks to the pandemic and the lockdowns that came with it I had grown nostalgic about the magic of unhurried traveling. The joy of settling down with a nice book on a long train journey, of watching the shifting landscapes float by, feeling the rush of wind through the open windows and the occasional explosive rush of a passing train, tasting different foods (and drinking the awful tea!) along the way; the chance to meet and travel with all sorts of different people... just about everything that seemed the opposite end of a lockdown spectrum :)

My two-week itinerary was fairly simple - a 2400km train ride to Bangalore (Train 06528), to be picked up by friends for a drive across the border from Karnataka to Krishnagiri district in Tamil Nadu. A couple of days later, another longer road trip to Thiruvananthapuram in Kerala, a week with the family, and finally,  the 3040km long rail journey (Train 02625) back to Delhi. 

Two train journeys ~ 5,500 km

Traveling under the shadow of an impending "third wave" of the pandemic, I had expected to see a lot of restrictions along the way. Sure enough, railway stations along the route were a lot less crowded than usual. This may have been because access to the platforms is now tightly controlled, visitors are no longer issued "platform tickets", nearly all hawkers were in designated uniforms and everybody was wearing a face-mask, at least to avoid getting penalised. 

However once the train rolled out of the platform in New Delhi, ticket examiners were not checking to see if passengers had been vaccinated. Hygiene and safety standards had improved though - cleaning of the coaches and mopping with disinfectants was more frequent, a couple of armed police officers patrolled up and down the trains, reminding everybody to keep the doors closed and even warning us to down the shutters and stay away from the windows at a place in Maharashtra because "children pelt stones in this area!".

All along the journey across multiple states, only at one station did RTPCR test results become an issue. At Bangalore Cantonment as soon as passengers disembarked, all of us were lined up for a quick health-check: 

"Are you coming from outside Karnataka? Where are you going? Do you have an RTPCR negative report? If not, what is your mobile number?"

Straight, simple questions. I had not taken an RTPCR test 72 hours prior to this journey. For a moment I though they were going to send me off to a week-long quarantine but quickly realised that this was just a precautionary measure. The staff who noted down my mobile number checked with the national database accessed through the CoWIN app. Once it was confirmed that I had taken both shots of the AZ-CovidShield vaccine, my destination details were logged in and swab samples were taken for an RTPCR test. By the time I stepped out of the railway station, a message had come in, reminding me of the precautions to be taken, and within the next 24 hours, I had a digital certificate confirming an RTPCR negative report - all for free! Totally understated, efficient and super impressive.

On both the long distance journeys - from Delhi to Bangalore and from Thiruvanantapuram back to Delhi - one big change was that there were very few people travelling all the way. On the onward trip, most of my co-passengers were migrant workers - mostly travelling from the northern states of Uttar Pradesh and Bihar to serve factories, malls and the gig economy for sending money back home. There were also a few tech workers - interns or trainees taking up their assignments in Bangalore and discussing the finer points of Java and Python along the way.

The return journey from Kerala was quite different. Most of my travel companions from Kerala got off just across the state border in Coimbatore, an industrial city that attracts a lot of workers and students; those who boarded from Tamil Nadu were again traveling a short distance to Tirupati, a centre for pilgrimage. My coach was practically empty when it passed through the states of Andhra Pradesh, Maharashtra, and Madhya Pradesh. 

The fear of Covid had transformed many of the landmark stations along the way. The famous stalls selling fresh fruit juice had disappeared from Vijayawada station; Chilly chicken was no longer on the menu at the Warangal station canteen. Hygiene seemed to have become an overriding concern - meals were now being sold in sealed plastic trays. Flexible pricing was also in - an egg biryani which cost INR 90 at 12:00 when the train reached Warangal would be available for INR 50 when the train reached Vijayawada a few hours later. If you were not in a hurry to pick up a packet as soon as the train stopped the price would go down still further to INR 40!

Another great transformation was the near seamless availability of broadband internet through the journey. Except for a few uninhabited areas of Telangana and Madhya Pradesh you can use the net to check the news feeds, catch up with old friends on WhatsApp, watch YouTube videos and, most importantly, see your own train moving across the country as a blue dot on Google Maps. This not only allows you to read up on the history and geography of the places you are passing through but also be well prepared to compose photographs of the fleeting yet stunningly beautiful landscapes of !ncredible India!

The Covid Pandemic seems to have changed not only the way in which Indian Railways operates  but also reduced the sense of chaos and uncertainty associated with train travel. If this trend continues I will be looking forward to my next long distance train ride - maybe from Gujarat to the North Eastern states for a change!

Sunny Days

 The precise shifting positions of the rising and setting sun through the year is a phenomenon observed thousands of years ago. The ancient Egyptians aligned their buildings - especially the pyramids - in such a way that sunlight entered the deepest passages only on certain days of the year, such as the summer equinox. The ancient Aztecs did the same, and so did the builders of Angkor Wat, and even the Padmanabha Swamy Temple in Kerala.

While it is relatively easy for communities that have lived at a particular location for many years to accurately predict the play of sunlight and shadows in their buildings through the year, the trick is to figure out how this would change in different parts of the globe. Consider this excerpt from an astronomy website - 

At 40°N latitude (Denver, Colorado / Beijing, China), the sun shifts 7° north. Since the sun's diameter equals 1/2 degrees, that means the sun has been traveling its own diameter (14 days x 1/2 degree = 7 degrees) northwards each day. At 60°N latitude (Fairbanks, Alaska / Siberia), the sun moves about 2 sun diameters or one degree daily.

How did they come to the conclusion that "the sun's diameter equals 1/2 degrees"? What exactly does this mean, especially when you consider the fact that the distance between the earth and the sun varies from summer to winter making it appear larger or smaller across the seasons? 

Things get a little more complicated here. Yet all this has been figured out with such amazing accuracy that we have websites that map the position of the sun to any given location on earth, any time of the year.


What we see here is a sun-path polar chart superimposed on an image from Google Maps. Each point on this is worked out by feeding in the local latitude in relation to the elevation of the sun and the time of day, for that location. For instance, Noida located at approx 28°N would see the sun at an elevation of 62° from the horizon  (90° - 28°) on equinox days (21 Mar., and 21 Sep.).

Solar Altitude (cc - Hartz ) 

This explains why cities located on or near the equator (eg., Singapore - 1.29°N) see very little variation in the position of the sun across seasons. So when a Singaporean stretches his neck to squint at the blazing sun right overhead on an equinox day, a Norwegian resident at the northern-most city in the world, Longyearbyne (78.22°N) would find the same mid-day sun hovering near the horizon all day!

Books of the World

 


Every now and then the great circus of Whatsapp forwards comes up with a gem, and this is one of them. A beautifully illustrated poster on the "Most Translated Books of the World" by Preply.

A closer look at this tells you that some non-empirical method has been chosen for the selections here.  Perhaps they have excluded books of religious nature, or those that may may be categorised as 'adult literature'. How else can one explain the fact that Paramahamsa Yogananda's "The Autobiography of a Yogi" is listed as the most translated book from India over "The Bhagawad Gita" or "Kamasutra"?   

At least according to the referenced list compiled by Wikipedia, the most translated book from India is the Gita, followed by Isha Upanishad and Yogananda's book in the third place. 

The list has its surprises too. For instance I was surprised to learn that a book we studied at school, "My Name is Aram" by William Saroyan the top book from Armenia. Also Arthur Hailey's "Hotel" is listed as the most translated book from... the Bahamas! 

Minor quibbles aside this remains a beautiful piece of work. The books I have not yet read from this list should keep me busy for a while! :)

NB: This is also the first time I am seeing a digital image presented in the <webP> format. At just over 600kB this seems to pack in a much more scalable image compared to JPEG or TIFF.  Seems to be an innovation from Google that uses a technique called predictive coding.
