Work on the RRTS Delhi-Ghaziabad-Meerut corridor accelerates in 2021

With a design speed of 180 km / h and an average speed of 100 km / h, RRTS aims to bring people and places together in the National Capital Region (NCR) and to provide fast, safe, transport solutions, reliable, comfortable, efficient, fluid and durable. .

“The year 2021, despite the adversities brought by the spread of Covid-19, has been a tremendous year in advancing the Regional Rapid Transit System (RRTS) project. Much has been accomplished and much has been accomplished and much has been achieved. work has accelerated, “said an official. NCRCT Manager.

The NCRTC began construction of the Duhai depot earlier this year. The Duhai depot will play a critical role in managing the operations of the 17 km long priority section of the corridor comprising five stations: Sahibabad, Ghaziabad, Guldhar, Duhai and the Duhai depot.

The depot will have stall lines, a maintenance facility, an automatic train washing station, a driver training center, a back-up operational control center and a control center. of the deposit.

The elevated part of Delhi for the RRTS corridor starts from the Sarai Kale Khan RRTS station, passes over Barapullah Flyover and crosses the Yamuna River to reach the New Ashok Nagar RRTS station.

To connect the elevated structure, construction work in Delhi has ramped up this year.

While the first jetty of the elevated section of the RRTS corridor in Delhi was built in June, since then many pillars have been put in place and a viaduct is being built near the Ashok Nagar RRTS station.

The year 2022 will see construction at a rapid pace in Delhi as the city prepares for India’s first regional train.

The first bridge under construction, which runs parallel to DND, has also seen increased activity and well foundations for the same are being done at a rapid pace. The 1.3 km long RRTS bridge will have 32 piers and 44 m long spans to connect these piers.

This year was also marked by the start of construction work on the underground stations. In addition to the elevated section, construction of the underground section of the RRTS corridor began with the concreting of the cast wall (wall D) of Delhi and Meerut stations.

To build a metro station, the first wall D must be built, then the hall and platform levels are built.

In Delhi, in Anand Vihar, construction of the tunnel boring machine (TBM) – “Sudarshan” launching shaft has started for the tunneling works. With this milestone, the construction of this underground section for the RRTS corridor has entered the next phase.

NCRTC has successfully completed the installation of the first special steel span of the RRTS Delhi-Ghaziabad-Meerut Corridor on the Indian Main Line crossing near Vasundhara, Ghaziabad.

The special steel span is 73 meters long and weighed approximately 850 tonnes. It was installed on pillars about 10 meters high on both sides of Indian railway tracks using a winch and roller device.

State-of-the-art, low-maintenance RRTS track laying has started between Guldhar and Duhai. It all started with the arrival of the rails and currently the welding of the rails is in progress.

All of these will contribute to the final stages of the Priority Section which will take its final form in the coming year – 2022.

Under the “Make in India” guidelines, a precast track slab factory has been established at Shatabdi Nagar in Meerut by the NCRTC. The NCRTC uses ballast-less tracks for a rated speed of 180 km / h for RRTS trains. Since there is no certified ballast-free track available in India for this speed, the NCRTC opted for the “precast slab track system” for the RRTS track.

Production of modern trainsets for the RRTS Delhi-Ghaziabad-Meerut corridor has started at a factory in Savli, Gujarat, by the NCRTC. These trainsets use advanced next-generation technology for a comfortable riding experience. The production of 40 sets (30 sets for the RRTS train of six cars each and 10 sets for the MRTS train (Mass Rapid Transit System for local transit in Meerut) of three cars each) is underway. The trainsets are expected to arrive in 2022 for testing which is expected to begin next year.

Screening doors (PSD) were first developed in India by the NCRTC this year. PSDs, which were imported until now, will now be made in our country. DSPs have become a vital component of modern transport infrastructure.

These act as a safety barrier between the platform / train / track and commuters, in addition to helping better crowd management at stations. For starters, Duhai Depot will be the first RRTS station to be installed with native PSDs.

The production of elevators and escalators started this year and next year will see their installation, from the Duhai depot.

The five priority section RRTS stations have all started to take shape. Crossed arms of Sahibabad and Ghaziabad were established and shaped the hall level of both stations. For Ghaziabad station, I-beams were installed for the construction of the platform level.

Work has started on the hall and platform of Guldhar and Duhai stations. At the Duhai depot, construction work on the Operation and Control Center (OCC), parking and inspection lines for RRTS trains has started. The coming year will see construction being completed at a level of ongoing testing and possibly the start of operations.

Work has also started for the installation of five receiving substations (RSS) for the power supply of the entire RRTS Delhi-Ghaziabad-Meerut corridor.

An RSS (Receiving Substation) is being built in Ghaziabad to supply the priority section where electricity will be drawn from the UPPTCL (Uttar Pradesh Power Transmission Corporation Limited) grid.

The RSS will convert it into a capacity of 25 kV and 33 kV using transformers thus ensuring the continuous supply of the train and the RRTS station respectively. With this, RRTS is moving towards the operationalization of the project.

The NCRTC has also started the installation of aerial equipment (OHE) on the viaduct in the 17 km long priority section. In the priority section, the erection of 30 percent of the masts is complete, while the balancing is in progress.

As part of the first phase of the installation process of the HEO, masts were erected on the constructed RRTS viaduct.

The year saw the NCRTC move to a new headquarters – GatiShakti Bhawan, located at INA market in Delhi.

The NCRTC is in the process of finalizing the supplier for Automatic Fare Collection (AFC) which will offer ticketing based on a QR code (Digital QR & Paper QR) and a contactless card EMV (Europay, Mastercard, Visa) and RuPay Open Loop based on NCMC (National Common Mobility Card).

Thus, RRTS commuters will be able to use any NCMC card issued by any metro or transport authority or financial institutions in the country.

At present, more than 14,000 workers and 1,100 engineers are working tirelessly on the 82 km long RRTS Corridor where approximately 1,200 pillars of the elevated section have been erected, over 50 km of foundation works and approximately 14 km of viaducts have been completed.

Trials on the priority section are expected to begin in 2022 with trains arriving in the city soon.
