How can a country be smaller than a Delhi neighbourhood and still have its own prince, its own borders, its own administration and enough national pride to make a full-sized flag look slightly embarrassed...

What happens when nature pours all her beauty into one small country, wraps its mountains in snow, and humans build trains that climb slopes steep enough to make even gravity nervous? Welcome to Switzerland.

We climbed into a boat that cheerfully ignored personal space and took us remarkably close to Europe’s largest waterfall by sheer volume, the Rhine Falls near Schaffhausen, Switzerland. The closer we got, the louder the roar became. The river seemed to be shouting, “Come closer, brave humans! I have a free facial and a mild cardiac workout for you!"

Our bus rolled into Heidelberg at around ten in the morning. Fresh from a sumptuous breakfast at our Frankfurt hotel, we were energised, curious and ready for another round of European sightseeing. But something changed almost immediately.

The city disappeared almost without warning. One moment we were leaving behind Heidelberg’s old streets, the Neckar River, the ruined red-sandstone castle high on the hillside, and the graceful arches of the Old Bridge. The next, our bus seemed to have entered a different Germany altogether.

Students marched. Cockroaches protested. And somewhere in between, an Indian tourist was desperately searching for a free toilet.

Paris did not simply welcome us. It put us through a little entrance exam, complete with cultural jet lag, linguistic curveballs, and a sudden realisation that the traffic rules here appear to have been designed by someone who once lost a bet with chaos.

In one astonishing day, we ‘invaded’ three countries. France, Belgium and the Netherlands fell before our comfortable tourist bus, and by night we had reached Frankfurt in Germany.

Is London just Big Ben, Buckingham Palace and the Thames? After spending a few days there, I felt the real story of London isn’t in its stone buildings but in the people who live their lives among them.

Indian Railways flagged off India's first Hydrogen Fuel Cell Trainset, a train that generates its own electricity onboard using hydrogen, the cleanest fuel known, recently. It produces near-zero emissions at the point of use. This milestone marks the latest chapter in the evolution of how Indian Railways has powered its trains, reflecting India's broader journey from coal and steam to cleaner, more sustainable sources of energy.
