- India's first dedicated railway test track is under construction between Gudha and Thathana Mithri, beside Sambhar Lake — a ₹820-crore RDSO facility about 80 km from Jaipur, per DD News.
- Dainik Bhaskar reports the North Western Railway GM inspected the 64-km track in August 2026 and said trains will be tested at speeds of 250 km/h, describing it as a national centre for high-speed rail testing.
- For the Phulera–Sambhar–Naraina land belt this adds a second national-scale rail project to the one it already has — Phulera's Dedicated Freight Corridor junction.
- It is a strong reason to look at the belt, not a substitute for due diligence. Land is market-linked; a corridor story is a factor, never a guarantee.
Most infrastructure news about small-town Rajasthan reads the same. This one is different, because the project is not passing through the Sambhar area — it is being built for it, permanently. Here is what the two reports say, with links, and what a land buyer should actually do with the information.
What was announced, and by whomक्या घोषित हुआ, किसने
Dainik Bhaskar (Sambhar edition, August 2026) reported that North Western Railway General Manager Pankaj Sharma inspected the 64-km high-speed test track under construction between Gudha–Thathana–Mithri in the Jodhpur division, saying trains would run at 250 km/h and that the Sambhar Lake area would become the country's national centre for high-speed rail technology and modern train testing. He also visited Phulera Junction and Sambhar railway station with the Jodhpur DRM to review passenger amenities and ongoing works, and received a memorandum from the Sambhar rail passengers' association seeking stops for more important trains at Sambhar. Officials described the facility as the country's first state-of-the-art rail testing lab — AI, high-resolution cameras, sensors and data-recording systems capturing lakhs of technical data points per second to analyse train stability, braking, wheel–rail interaction and aerodynamics. Read the original: Dainik Bhaskar's report.
DD News (November 2024) had earlier reported the project as India's first dedicated railway test track, sanctioned in two phases (2018 and 2021) at a total cost of ₹820 crore, located near Sambhar Lake in the Deedwana district, about 80 km from Jaipur, overseen by RDSO. That report described a ~60-km layout with speeds up to 230 km/h, 7 large bridges, 129 small bridges and four stations — Gudha, Jabdinagar, Nawan and Mithari — with stainless-steel components chosen specifically to resist Sambhar Lake's alkaline environment, and testing to be offered to neighbouring countries as well.

Why this belt keeps attracting infrastructureयह बेल्ट ही क्यों
The test track is not arriving in an empty landscape. Phulera Junction is already a Dedicated Freight Corridor node; the Jaipur–Ajmer highway corridor runs along the belt's southern edge; and the Naraina–Rupangarh corridor ties the interior villages to both. A national testing facility adds something the belt has never had: a permanent institutional anchor. Railway testing is not a construction project that ends — it is decades of engineers, contractors, suppliers, visiting delegations and station traffic, in an area whose stations (per the Bhaskar report) are already being upgraded.
That is the pattern buyers watch for: not one project, but projects that reinforce each other. Freight (DFC), passenger (station upgrades, the demand for more train stops), and now institutional (RDSO's national lab).
"Gold mine" — the honest version"सोने की खान" — ईमानदार जवाब
Is investing near Sambhar a gold mine? Here is the version we can stand behind. The ingredients that have historically preceded land-value growth in this district — a national-scale anchor project, multiple reinforcing corridors, cheap entry prices relative to Jaipur's urban fringe, and visible state investment — are present and documented above. That is genuinely rare, and it is why AgriZameen's own Focus Belt is exactly this stretch.
What nobody can promise you is timing or magnitude. Corridor stories run ahead of the ground: prices near announced projects often move on the announcement and then wait years for the reality. Land is market-linked, illiquid, and can fall as well as rise. The historic appreciation seen near completed infrastructure in the Jaipur–Ajmer belt (see the footnote in our site footer) is an observation about the past, not a forecast. Anyone who tells you otherwise is selling, not informing.
The risks the headlines skipजो जोखिम सुर्ख़ियों में नहीं हैं
- Alignment and acquisition: land touching a rail corridor can be subject to acquisition, setbacks and access changes. Ask specifically whether any khasra you are shown falls under a notification.
- The lake itself: Sambhar is a Ramsar wetland with salinity-affected land around it. Parts of the area are unsuitable or restricted — our Sambhar wetland & salinity caution and Nawa salt-belt caution cover which questions to ask.
- Corridor-story pricing: sellers quote the news, not the record. The corridor-belt red flags guide lists the standard tricks — inflated "project-adjacent" premiums, plots sold twice, unconverted land marketed as plots.
- Barani reality: much of the belt is rain-fed (barani) land. The classification is on the jamabandi; the cropping truth is in the girdawari.

FAQ · अक्सर पूछे सवाल
Where exactly is the high-speed rail test track being built?
Between Gudha and Thathana Mithri near Sambhar Lake, in the Jodhpur railway division, roughly 80 km from Jaipur. The corridor sits alongside the Phulera–Sambhar–Naraina belt that AgriZameen covers, with stations reported at Gudha, Jabdinagar, Nawan and Mithari.
Does the test track guarantee that land prices near Sambhar will rise?
No. Infrastructure of this scale changes activity in a belt — workforce, contracts, visibility — but land is market-linked and can fall as well as rise. Treat the project as one factor among many, verify every record, and never buy on a corridor story alone.
Can I buy agricultural land right next to the test track?
Land near any railway corridor can attract alignment, acquisition and setback issues, and parts of the Sambhar area carry wetland and salinity restrictions of their own. Check the khasra against current records, ask about any acquisition notification, and take legal advice before committing.
What should I verify before buying in the Phulera–Sambhar belt?
The jamabandi and its mutation history, the khasra on Bhu-Naksha, girdawari for actual possession, land classification (much of the belt is barani), any Section 90A conversion status, and — near the lake — the Ramsar wetland and salinity constraints. Our belt guides walk through each step.
