About the Project:
- NCRTC has geared up construction activities on India’s first Regional Rail between Delhi-Ghaziabad-Meerut.
- Superstructures are now visible on the Delhi-Ghaziabad-Meerut RRTS corridor.
- Also, work for the RRTS viaduct near Dharamshila Marg, New Ashok Nagar in Delhi has already been started.
- In this 4.3 km elevated section of Delhi-Ghaziabad-Meerut RRTS corridor, there will be the construction of a viaduct from Sarai Kale Khan RRTS Station to New Ashok Nagar Down ramp, including Jangpura entry ramp to the stabling yard, Jangpura.
- Two elevated RRTS stations, namely Sarai Kale Khan & New Ashok Nagar, will also be constructed, including a bridge over the Yamuna River.
- The RRTS will have a total length of 82.15 km (68.03 km elevated and 14.12 km underground) with 25 stations.
- It will have a design speed of 180 km per hour, maximum operating speed of 160 km per hour and high-frequency operations, which will reduce the journey time from Delhi to Meerut to 60 minutes.
NCRTC adopts CORS technology:
- CORS-Continuously Operating Reference Station – is a global positioning system (GPS) based technology mainly used in surveys, mapping, and allied services.
- This technique ensures complete accuracy in the construction of a predetermined corridor in civil construction so that the planned alignment can be achieved.
- Delhi-Ghaziabad-Meerut is an 82 km long corridor going over rivers, railway lines, roads, expressways, and flyovers.
- Hence it is very important to maintain accuracy in civil structure alignment.
- Keeping this in mind, the NCRTC went beyond the traditional technologies and adopted an ultra-modern survey technique, CORS, which is being used for the first time in the country in any mega infrastructure project.
About CORS technology:
- CORS is a network of ‘reference stations’ that are established at every 10-15 kilometers along with the Delhi-Ghaziabad-Meerut RRTS corridor, these CORS ‘reference stations’ are connected to the “Control Center”, which provides the real-time data to the rovers collected from 3-5 reference stations.
- The entire process of data collection enables the rovers to achieve accuracy of up to 10 mm.
- Also, given the limited timeframe for the implementation of the country’s first RRTS project, the construction work is in progress at multiple sites simultaneously.To ensure that construction at multiple locations does not impact the accuracy of the project, CORS is being used as it mitigates the risks of any kind of error during the construction.
- The CORS network is set up for the first time in the country for a rail-based project, the system is set to be a path-breaking system for such projects to conduct surveys.
