[Parimal @Fintech03]

In the scorching summer of 1984, the Northern Railway reservation office at New Delhi station was a circle of hell.

100,000+ passengers descended on the station daily. Behind wooden counters sat clerks buried alive under 1000s of bound, leather-backed ledgers called Charting Sheets. To book a ticket, a clerk had to physically find the ledger, cross out a berth with a fountain pen, hand write a paper ticket, and file a duplicate slip.

If you wanted a return ticket from Madras to Delhi? You could not buy it in Delhi. You had to send a physical telegram to Madras, wait 48-72 hours for a manual reply, and pray the seat was not sold twice.

This is where CMC Limited (Computer Maintenance Corporation) slowly entes into the scene, a public sector company staffed by young, intense Indian systems engineers, working alongside a dedicated task force from Indian Railways.

The mandate was terrifying: Digitized reservation did not exist at this scale in the developing world. Foreign vendors wanted astronomical sums for custom software. The team had to build it from scratch, using bare metal hardware.

They chose VAX/VMS minicomputers and picked a language built for raw numerical calculation, not transaction processing: FORTRAN.

They named the software IMPRESS (Integrated Multi-train Passenger Reservation System).

On 15th Nov, 1985, a quiet pilot went live at New Delhi station for just 2 trains: the Tamil Nadu Express and the Grand Trunk Express.

There were no satellite beams / grand reveals. The software was bug riddled, the clerks were terrified of the green phosphor CRT monitors, and paper backups were kept open on the desks just in case the system crashed.

When the 1st green terminal screen printed a clean, automated ticket in < 60 secs without a clerk touching an ink pad, the engineers in the back room did not celebrate. They held their breath, waiting for the system memory to dump.

It did not......

By 1987, IMPRESS was expanded to Bombay, Calcuttta, and Madras. But there was a catch: They were island nodes.

Bombay had no idea what Calcuta was doing. A clerk in Delhi could still only sell tickets for trains originating out of Delhi.

To manage this growing digital beast, Indian Railways created CRIS (Centre for Railway Information Systems). CRIS inherited 5 massive regional databases: Delhi, Bambay, Calcutta, Madras, and Secunderabad.

Each region was an isolated digital kingdom running on different hardware iterations.

As travel exploded in the 1990s, the "Island Problem" became a crisis. Passengers did not travel in single regions.....

CRIS engineers were tasked with the ultimate computer science nightmare: How do you synchronize 5 massive, high throughput, realtime transaction databases across 4,000 KMs over unreliable copper telegraph lines and primitive telecom links?

If a user in Secunderabad tried to book a seat on a train running from Howrah to Bombay while a user in Ahmedabad tried to book the exact same berth at the exact same second, how do you prevent a deadlock without crashing the entire national network?

The CRIS team went to work on a master architecture: CONCERT (Country-wide Network for Computerized Enhanced Reservation and Ticketing).

They had to engineer custom distributed database protocols. They built networking software that could handle dropped packets, noisy BSNL landlines, and sudden power blackouts. Where landlines failed, they rigged up hybrid data pipes, combining microwave links, leased telecom lines, and early satellite VSATs for redundant failovers.

The system was rolled out region by region starting in 1994. The pressure on the CRIS software architects was unbearable, a single logic bug in memory locking could lock up 100s of 1000s of seats across the nation, halting the economy overnight.

Finally, in April 1999, the final switch was flipped....

For the 1st time in human history, a passenger walking up to a remote ticket window in Guwahati could instantly query, lock, and purchase a ticket for a train running between Trivandrum and Mumbai in < 2 secs.

It was a 15 year relentless siege by teams at CMC and CRIS, writing low level C and FORTRAN code, fighting hardware limitations, and building custom networking protocols long before modern cloud infrastructure existed.

When IRCTC was launched in 2002 to bring ticket booking to web browsers, it did not build the core reservation engine. It simply built a web frontend that plugged into the massive, bulletproof CONCERT backend built by CRIS.

Today, that same underlying architectural logic handles over 1.5M+ bookings a day, serving a population larger than entire continents.

Remember, this was done without any massive VC funding. Just pure, unyielding Indian engineering built line by line in the dark.

What @palkisu is saying makes sense. When algorithms become teachers, reels become textbooks , virality becomes truth, when reading disappears, it is misinformation that flourishes. An uninformed generation can be a potential national security risk.
