Building Information Modelling
Combining multiple disciplines
BIM (Building Information Modelling) is an intelligent 3D model-based process that
provides architecture, engineering, and construction professionals the insights & tools
to more effectively plan, design, construct, and manage buildings & infrastructure.
All components are modelled in 3D with the help of various BIM software and a single
database (BIM model) combines information from all disciplines – Architecture, Structure,
Mechanical, Electrical, Plumbing and Fire Safety (MEPF) etc. This is further used to extract
drawings and other information in the form of BOQs, reports, etc. Working in this
collaborative environment ensures that the design development happens on the latest
information available, for example the MEPF services design happens on the Architecture
BIM model which ensures reliability of architectural and structural data.
Currently, all the RRTS stations are being designed and developed on BIM platform.
Common Data Environment:
NCRTC planned to maintain common repository of all construction and pre-construction drawings and technical documents in digital format at a centralized repository, so as to enable fast retrieval of these documents as and when required from anywhere. For this purpose, NCRTC uses an indigenously developed “Common Data Environment (CDE)” – a central repository to store and share data in real-time.
CDE is a user-friendly solution which is mobile accessible and allows online viewing, sharing, and commenting of all project-related documents, drawings, & models. The in-built workflow management in the CDE system enables digital workflows for preparation and approval of all types of drawings & technical documents from different stakeholders at various levels of hierarchy. Thus, it enables greater transparency, efficient search, and retrieval of data.
Continuously Operating Reference Station
NCRTC is using Continuously Operating Reference Station (CORS) network with multiple Global
Navigation Satellite System (GNSS) base stations which are located at stable locations.
These stations operate 24 X 7 at a distance of 5 to 10 km along the corridor, which
eliminates dependence on distance, ionospheric & manual errors in survey. Using the rovers
within the CORS Net, surveyors can provide accurate (x, y) coordinates on ground
(within 10 – 12 mm accuracy of location) and eliminate the existing process of everyday
orientation of Total Station. This saves time without the fear of manual errors.
CORS technology provides real time precise coordinates for the measured locations and
is capable of ensuring 5-10 mm accuracy in location points for accurate civil
ETCS L2 Signalling and Train Control System
European Train Control System (ETCS) Level 2
RRTS will have European Train Control System (ETCS) Level 2 which includes Automatic Train Protection (ATP), Automatic Train Operation (ATO), and Automatic Train Supervision (ATS) sub-systems using radio communication between track side and train. ETCS Level 2 signaling will be used for the first time in India, which involves continuous supervision of train movement with continuous communication between the train and trackside using Long Term Evolution (LTE).
Lineside signals are optional and train detection is performed by trackside equipment. ATP, ATO, and ATS will provide high level of safety for trains running at close headway to ensure continuous and safe separation, eliminate accidents due to driver error, maintain safe speeds, optimize speed, maximize turn-around, and monitor trackside & train-borne equipment to enable on-time preventive maintenance. ETCS Level 2 system will allow interoperability among different RRTS corridors.
Automatic Train Operations (ATO) system, which controls the traction system, will help in acceleration, braking or stopping of trains resulting in easy driving. This technology will also sync Platform Screen Doors with the RRTS system for enhanced safety of passengers.
Integrated Real-Time Enterprise Asset Management System
The RRTS project is asset intensive and hence, management and maintenance of its assets through well-defined and coordinated processes plays a key role in the success of the project. NCRTC is implementing an Integrated Real-Time Enterprise Asset Management System (iDREAMS) which would ingest real-time data from different sources and other subsystems such as BIM, GIS, IoT, OCC, SCADA, BMS etc. during the design and construction phase. iDREAMS would bring digital transformation in the way rail assets are being managed in India.
Automatic Fare Collection
NCRTC is adopting Automatic Fare Collection (AFC) system for Delhi- Ghaziabad- Meerut RRTS corridor. AFC will offer QR Code based ticketing (Digital QR & Paper QR). Each Ticket Vending Machine (TVM) shall be equipped with a credit/debit/pre-paid card reader compliant with EMV (Europay, MasterCard, Visa), RuPay standard for non-cash payment of transactions. This will ensure a contactless entry/exit that will be seamless, easy, comfortable, and quick.
Platform Screen Doors
Platform Screen Doors (PSDs) will be used to isolate the platforms from the track. PSDs will open only when the train stops at the correct position. The use of PSDs will help to prevent accidents, objects falling on track, and trespassing. PSDs will be synchronously controlled throughout the length of the platform. PSDs which are on the platform will operate in synchronization with the Train doors. PSDs will be installed at every RRTS station that will help in saving significant energy consumption and ensure enhanced safety of passengers.
NCRTC has taken the initiative of bringing the technology of manufacturing PSDs in India, towards the aim of ‘Atmanirbhar Bharat’ by adopting ‘Make in India’ in its true spirit. There exists huge demand for affordable locally produced PSDs in upcoming & existing Metro/RRTS and High-Speed Rail systems in India.
RRTS trains will have push buttons for selective opening of doors, which will be need based. This will eliminate the opening of all doors at every station, thus leading to energy saving.
Regenerative Braking System
RRTS trainsets will be provided with the state-of-the-art Regenerative Braking System which converts the train’s kinetic energy into electrical energy.
