How long is the rail corridor in Singapore? 24km total length

Exploring how long is the rail corridor in singapore reveals a vast green artery perfect for outdoor enthusiasts seeking island-wide connectivity. Understanding the full distance helps visitors plan their journey effectively while avoiding missed access points behind industrial estates. Learning the trail reaches provides insight into the local urban nature landscape.

Exactly how long is the Rail Corridor in Singapore?

The Rail Corridor in Singapore is a 24-kilometer (approximately 15-mile) continuous green artery stretching from the Woodlands Train Checkpoint in the north to the former Tanjong Pagar Railway Station in the south.

Currently, roughly 21 kilometers of the trail are fully accessible to the public, offering a seamless path for walking, jogging, and cycling. It is quite a distance. But theres one specific 2-kilometer stretch near the northern end that even regular hikers often miss because the access point is tucked away behind a nondescript industrial estate - Ill reveal how to find it in the Hidden Gems of the North section below.

This 24-kilometer length represents a significant transformation of the former Keretapi Tanah Melayu (KTM) railway line into a multi-functional public space. While the total distance remains fixed, the experience varies as you transition from the rustic, unpaved northern stretches to the highly manicured central zones. Ive walked the entire length three times now, and every time Im struck by how the air temperature seems to drop by 2 or 3 degrees the moment you step under the canopy of the Clementi Forest. It is a long journey, and considering how long is the rail corridor in singapore, it feels even longer under the heat.

Breaking down the sections: North, Central, and South

To understand the length better, it helps to view the corridor in three distinct segments. The North segment spans approximately 10 kilometers, running from Woodlands Road to Hillview. This part of the trail is often preferred by those seeking a more rugged experience, as it features wider paths and closer proximity to the Sungei Kadut industrial area and various nature parks.

The Central segment is arguably the most famous part of the 24-kilometer stretch. It covers about 4 kilometers between Hillview and the Bukit Timah Railway Station. This section was a major focus of restoration works, resulting in improved accessibility and the preservation of iconic heritage structures. In my experience, this is where the crowds are thickest - especially on weekend mornings - so if youre looking for a quiet walk, you might find this section a bit overwhelming. The gravel paths here are meticulously maintained, making it the easiest 4 kilometers of the entire trip.

Finally, the South segment extends about 10 kilometers from the Bukit Timah Railway Station down to the Spooner Road area near Tanjong Pagar. As of early 2026, major works around the former Tanjong Pagar Railway Station have integrated more of the southern tip into the accessible path. The transition from the lush greenery of the Buona Vista area to the urban skyline of the Central Business District provides a dramatic conclusion to the Singapore Rail Corridor total distance.

How long does it actually take to walk the Rail Corridor?

Rail Corridor Singapore walking time typically takes between 5 and 6 hours for the average pedestrian, assuming a steady pace of 4 to 5 kilometers per hour. This timeframe includes short breaks for hydration but doesnt account for long stops at nearby cafes or extensive photography sessions at the heritage bridges. For cyclists, the journey is significantly faster, usually taking between 1.5 and 2 hours depending on trail conditions and foot traffic.

When I first attempted the full 24-kilometer walk, I made the mistake of starting at 9 AM. By the time I hit the 12-kilometer mark near Bukit Timah, the humidity was brutal. My energy levels plummeted. Ive learned that in our climate, knowing can you walk the whole Rail Corridor Singapore isn't just about distance; its an endurance test against the heat. Most seasoned walkers recommend starting no later than 6:30 AM to clear the unshaded northern sections before the sun reaches its peak. If youre planning to do the whole thing, bring at least 2 liters of water. Youll need it.

Hidden Gems of the North: The secret 2-kilometer stretch

Here is that hidden section I mentioned earlier: the Kranji Node to Hillview stretch. While most people start at the Bukit Timah Railway Station, the northernmost 2 to 3 kilometers near Kranji offer a completely different vibe. To find the hidden entrance, you have to look for the small trail opening near the bus stop at the junction of Kranji Road and Woodlands Road. It looks like a simple dirt path, but it opens up into a stunning, wide-open vista that feels more like the African savanna than Singapore.

This northern stretch is where you can truly appreciate the Rail Corridor as an ecological link. Biodiversity records show that the corridor supports over 100 species of birds and a wide variety of butterflies. Because fewer people visit the far north, the wildlife is much more visible. Ive spotted the Changeable Hawk-eagle perched on the old telegraph poles twice in this specific area. Its a reminder that this 24-kilometer path isnt just for us; its a vital highway for the islands animals.

Is the whole Rail Corridor currently open?

As of 2026, approximately 97% of the 24-kilometer corridor is open and continuous. Small sections may occasionally close for localized maintenance or trail enhancement, particularly in the southern stretches near the Tanjong Pagar terminal. The goal has been to maintain a seamless connection, and the recent completion of the Buona Vista community knot has resolved one of the last major broken links in the southern half.

Its important to note that while the path is continuous, the terrain is not uniform. The southern stretch of the trail is paved with a porous, weather-resistant material designed to mimic the look of a natural path while providing a stable surface for wheelchairs and strollers. The remaining portions, mostly in the northern ends, consists of grass, earth, or stabilized gravel. This can get muddy after a typical Singaporean downpour, so your 24-kilometer trek might involve some tactical puddle-jumping if you head out after the rain.

Coastal paths and park connectors

Wei's weekend mission: Walking the full 24km

Wei, a 34-year-old software engineer in Buona Vista, decided to walk the entire 24 kilometers on a Saturday. He'd done the central 4 kilometers many times but wanted the achievement of the full cross-island trek. He started at Kranji at 8:30 AM with just one small bottle of water.

By the time he reached Hillview, 10 kilometers in, the sun was scorching. He realized he'd significantly underestimated the humidity and the lack of shops in the northern stretch. His legs felt like lead, and his water was gone three kilometers ago. He almost called a car to go home.

Instead of quitting, he rested under the Pelton Canal flyover and checked a map. He realized he could detour 500 meters to a nearby mall for supplies. After a 30-minute cooling break and a liter of isotonic drink, his energy returned. He adjusted his pace, focusing on short, 2-kilometer goals.

Wei finished at Spooner Road at 4 PM, taking 7.5 hours total. He lost 2kg in water weight but gained a deep respect for the trail's length. He now tells everyone: the Rail Corridor isn't a walk in the park; it's a marathon in a sauna.
