Few points in Delhi carry as much daily traffic through as many transport modes as Sarai Kale Khan. Sitting on the Inner Ring Road in South East Delhi, it’s where Hazrat Nizamuddin Railway Station, the Sarai Kale Khan ISBT, a Pink Line metro station, and — as of February 2026 — a brand-new RapidX regional rail terminal all converge within a few hundred metres of each other. This guide covers what each mode actually offers, how they connect to one another, and why this hub matters if you’re renting or buying anywhere near Nizamuddin, Jangpura, or Lajpat Nagar.
Key Takeaways
- Sarai Kale Khan RRTS station became fully operational on 22 February 2026, completing the Delhi-Meerut RapidX corridor and adding a fourth transport mode to the hub.
- Hazrat Nizamuddin Railway Station handles nearly 250 trains daily and is the origin point for Rajdhani Express services to Mumbai, Chennai, Bengaluru, and more.
- The RRTS station sits about 80 metres from the ISBT and 300 metres from the metro station, linked by footpath and a foot overbridge.
How Sarai Kale Khan Got Its Role as a Transport Hub
Sarai Kale Khan’s transformation into a multimodal hub happened in layers, not all at once. Hazrat Nizamuddin Railway Station (station code NZM) was developed to take pressure off the increasingly congested New Delhi Railway Station roughly 7 km to the north, and today handles close to 250 trains a day — one of only five primary railway stations in the Union Territory of Delhi. It’s named after the medieval Sufi saint Nizamuddin Auliya, whose dargah lies nearby.
The Sarai Kale Khan ISBT came next: construction on the ₹80-crore terminus began in March 1996, and it opened to the public in January 2005, built specifically to decongest the older Maharana Pratap ISBT at Kashmere Gate in North Delhi. It’s run by the Delhi Transport Infrastructure Development Corporation (DTIDC), a company wholly owned by the Delhi government.
The Sarai Kale Khan–Nizamuddin metro station arrived on the Pink Line on 31 December 2018 (initially named Hazrat Nizamuddin, renamed in 2019), tying the railway and bus terminus into the metro network for the first time.
What’s New in 2026: The RRTS Arrives
Why it matters: after years of delay, the Sarai Kale Khan RRTS station finally became operational on 22 February 2026, completing the full Delhi–Meerut RapidX corridor and making this the moment Sarai Kale Khan turned into a genuine four-mode hub. The station is a serious piece of infrastructure — six elevated platforms serving four tracks, spread across a building 215 metres long, 50 metres wide, and 15 metres high, built by Afcons Infrastructure for the National Capital Region Transport Corporation (NCRTC), a joint venture of the Government of India and the state governments of Delhi, Uttar Pradesh, Rajasthan, and Haryana.
Once the wider Delhi–Meerut corridor is fully built out, the ride between the two cities is designed to take around 55 minutes — a genuinely significant change for anyone commuting between South East Delhi and the NCR’s eastern satellite towns.
Rail, Road & Metro: What Each Mode Offers
Hazrat Nizamuddin Railway Station serves as an origin and terminating point for premier Rajdhani Express trains to Mumbai, Chennai, Bengaluru, Secunderabad, and Thiruvananthapuram, alongside dozens of other long-distance services. The station underwent a significant redevelopment and beautification push in recent years, upgrading passenger facilities considerably from its older layout.
Sarai Kale Khan ISBT runs short and long-haul buses to Haryana, Uttar Pradesh, and Rajasthan — this is typically where you’ll catch a bus toward Agra, Jaipur, or destinations across the Delhi–NCR belt, alongside the two other Delhi ISBTs at Kashmere Gate and Anand Vihar.
The Pink Line metro station ties the whole hub into Delhi Metro’s broader network, giving direct access toward Lajpat Nagar, South Extension, and onward across the city without needing to change transport mode at all.
Directions & What’s Nearby
Sarai Kale Khan sits on the Inner Ring Road, bordered by Nizamuddin East and West, Jangpura, and Sunder Nagar, with Lajpat Nagar and Defence Colony a short drive away.

What This Means for Renters and Buyers Nearby
A hub of this size tends to lift the profile — and eventually the price — of the neighbourhoods around it. Areas like Nizamuddin East, Jangpura, and Lajpat Nagar, already well-regarded South Delhi addresses, now sit within a few minutes of four separate transport networks. That’s a rare combination anywhere in the city, and it’s the kind of connectivity upgrade that tends to show up in rental demand well before it shows up in headlines.
