Lucknow Metro is alive with art

To give an impetus to the traditional handloom, handicrafts, tourism and MSME sectors, architect Arvind Kumar Dubey has installed artworks at the Lucknow Metro - depicting the rich heritage of the city

The North-South corridor of Lucknow metro spanning 23kms has been successfully completed in four-and-a-half years. The complete corridor from Chaudhary Charan Singh International Airport to Munshipulia includes 17 elevated stations, four underground stations and a metro depot located at Transport Nagar.

With innovation in design, planning, construction methodology and creative situational decisions on site, Lucknow Metro has revolutionised the way public projects are built in India and has earned itself the tag of fastest constructed metro rail project in India. Coupled with this, it has tried to achieve an amalgamation of technology and design in order to provide a comfortable and safe travel experience for commuters on the one hand and being a flag bearer of sustainability and climate justice on the other.

Architectural and design features of Lucknow metro stations:
Incorporating the vernacular ‘Awadh’ architecture and design elements of Lucknow into the architecture of metro stations. The vocabulary and building materials are modern and contemporary. but the heart beats find pulse from the art and history of Lucknow. There is an integration of Entry/Exit structures, especially at the underground metro stations with the given space constraints and without disturbing the services and old structures in the surrounding urban fabric. The colour scheme and design elements help to merge the structures with the surrounding built environment and scale.

Moreover, parameters like aesthetics, easy availability, manufacturing within India, lower embodied energy and fire proofing in material selection were given due consideration. Passive design elements are used to harvest daylight and natural ventilation effectively, thereby making the metro stations and depot energy-efficient with a lower carbon footprint.

Rain-water harvesting is maximised and energy-efficient technologies and novel systems like regenerative braking system in lifts and elevators have been used. The metro stations and depot are IGBC Platinum rated to provide green transportation.

The metro stations and structures are designed to ensure seamless integration with multi-modal transportation and Smart City infrastructure to ensure last mile connectivity and provide a world-class public transportation facility to the masses.

Efforts have been made to make public spaces and transportation accessible to all as envisaged in the Accessible India Campaign. There are adequate provisions of ramps and passage as per international standards, and elimination of unnecessary level differences to ensure unhindered movement.

To give impetus to traditional handloom, handicrafts, tourism and MSME sectors, artworks are installed depicting the finesse of artisans and rich heritage of this city. Thus, the artworks are not just artworks - but a story, capturing in it an era, a history and countless dreams of the people of this city.

Construction methodology:
The underground metro stations have been constructed as cut and cover with top-down method so that the surface could be restored quickly and further excavations and construction of the station will not hamper the surface activity. For the elevated stations, the superstructure has predominantly used prefabricated structural members.

A glimpse of awe-inspiring art at Lucknow Metro: 
Lucknow has been the cultural capital of Uttar Pradesh with its gifts to the world like Thumri, Chikankari and Awadh architecture. A successful attempt has been made at the city's metro stations to provide commuters with a soulful experience to add colour to their daily life and commute, and to make an impression in their memory and heart. 

These artworks depict the delicate Chikankari textile weaving of Lucknow, graceful ‘parchin-kari’ (marble inlay work/Pietra dura) of Agra, brass work of Moradabad, glazed Khurja pottery of Bulandshahar, and chandeliers and bangles of Firozabad.

Transit Oriented Development (TOD):
The complete corridor and its stations have been planned keeping TOD in mind. The North-South corridor connects the airport, bus station, railway stations to facilitate multi-modal connectivity. The service of e-rickshaws, called ‘metro-mitra’, connecting stations with its catchment areas and parking facility at various stations further the concept of TOD.

Sustainability:
There is an installation of more than 1 MW solar rooftop plant at the depot. The electricity produced is fed back into the grid. Moreover, the buildings like the training centre, depot control centre and workshop make use of ambient daylight and regulate temperature to enhance indoor comfort and energy efficiency. Approximately 45% saving in electricity is estimated by providing natural daylight to 80% of total station areas in elevated stations - that is, 100% on platform and 60% on concourse level.

Additional capacity of 2 lakh cubic metres has been created by incorporating rain-water harvesting structures into the station and depot designs. There is zero water discharge from the depot, and the harvesting structures help in augmenting the ground water level as well.

LMRC depot - Purpose and facilities:
Workplace for all minor, major and heavy schedules/repairs, maintenance and major overhauls of all the trains including wheel/pressing boring, etc. Depot has a capacity of as many as 42 trains of 6 cars each. It comprises a huge training centre for the workforce involved with LMRC. There is a state-of-the-art Centre of Excellence to inculcate and sharpen the technical and soft skills by way of traditional teacher-student interaction and modern simulators. 

Receiving substation for supply of 33KV and 25KV to station and overhead equipments. It houses power supply, power backup and distribution system. Labour-intensive procedures are kept to the minimum and automation with futuristic machineries to ensure quality with reliability.

Space for Central Control Centre for Operation of complete Metro Rail system. Depot consists of high-mast towers for lighting, and is interlocked and isolated from the mainline for the safe movement of the trains in the depot area.

Major features at LMRC Depot:
Depot Control Centre: Houses the Back-up Control Centre and Operational Control Centre for the priority section. Depot Control Centre enables train movement from the depot and a centralised office of operation wing of LMRC for the priority section. It also houses labs for signalling equipments, telecom and electrical equipments.

Under floor pit wheel lathe machine: Under Floor Wheel Lathe is an automatic machine for simultaneous profiling of new or worn-out wheels of metro cars. Tool will get automatically positioned and start cutting cycle in single or multiple cut, depending on the material to be removed. Only profiling or profiling with inside face machining will be done based on operator selection. The machine has been successfully installed, tested and commissioned at the depot.

Workshop and Inspection Bay: For monitoring and scheduled inspections of Rolling Stock and its equipments by condition monitoring of key parameters. Inspection Bay Lines have sunken floor and overhead roof inspection platforms. One of the first metros to use ‘puff insulated roof in curved profile’ and epoxy-based flooring. The bay has epoxy-based flooring to ensure hazard-free process monitoring and maintain clean environment, and puff insulated roof with turbofan and integrated transparent roof sheets to ensure optimum temperature and light control.

Auto coach wash plant: An automatic coach wash plant adheres to today's needs for not only maintaining hygiene, but also to save time and money, and is significant for free flow of the Metro service.

Stabling lines and Emergency traction unit (ETU): Stabling Lines (SBL) with insulated roof ensures comfortable maintenance in all seasons and facilitates uninterrupted service. Critical spares required to attend to any breakdown at the earliest are maintained in this store.

Centre of excellence for training: It has Computer Based Training facilities, model rooms, simulator of the train and classrooms with electronic boards. A state-of-the-art auditorium of about 150 seating capacity has been provided. The library building provides a good ambience for intellectual exercises and makes use of day lighting. The Centre of Excellence is planned to provide training of staff of Lucknow Metro as well as for neighbouring Metro for Kanpur, Agra, Varanasi, etc.

Receiving sub-station:  LMRC has constructed a 132/33/25KV receiving sub-station (RSS) at its Transport Nagar train depot. There are two sub-stations, namely the Traction Sub Station (TSS) and the Auxiliary Main Sub-Station (AMS). Once the power supply gets stabilised, it will be extended to the associated AMS, TSS and Auxiliary Sub Station.

Design of Rolling Stock (Metro train):
The design of rolling stock takes the local context to the next level. The headlights mimic the graceful eyes of a Kathak dancer and the front face element takes inspiration from the arched gateway –  'Rumi Darwaza', a landmark in Lucknow. The side elements are inspired from the motifs of local indigenous textile art of ‘Chikankari’.

The interiors are designed keeping ergonomics and user movement in mind so as to keep the movement safe, smooth and comfortable for one and all. Full use of energy-saving techniques like regenerative braking systems and LED lights make the best use of available energy.
