Metro Glasses — Duratuf Glass2026-07-01T07:01:50+00:00

Metro Glasses — Duratuf Glass

Metro rail systems have transformed how millions of people travel across India’s cities every day. From Delhi and Mumbai to Bengaluru, Chennai, and Hyderabad, metro trains carry passengers safely and efficiently through crowded urban landscapes. Behind this seamless travel experience lies a critical component that most passengers never think about — the glass.

At Duratuf Glass, we manufacture high-performance metro glasses for India’s growing metro rail networks. From driver cabin windshields to passenger side windows and interior glass partitions, our products combine safety, optical clarity, and durability to meet the demanding requirements of urban rail transport.

If you are looking for Heavy Vehicle Windows India or need reliable Industrial Vehicle Glass Solutions India, this page covers everything you need to know about our metro glass products, how they are engineered, and why metro rail operators and coach manufacturers across the country trust Duratuf.

What Are Metro Glasses?

Metro glasses refer to the various glass components used in metro rail coaches and locomotives. These include:

  • Driver cabin windshields — The front glass panels that provide visibility for the train operator
  • Passenger side windows — The windows alongside passenger seats that offer views and natural light
  • Interior glass partitions — Glass panels that separate different sections of the coach
  • Door glazing — Glass panels integrated into coach doors

Each type of metro glass serves a specific purpose and must meet strict safety, optical, and durability standards. Unlike standard building glass or even automotive glass, metro glasses are engineered to withstand the unique demands of urban rail transport — high speeds, frequent stops, tunnel pressure changes, and the constant vibration of steel wheels on tracks.

Why Metro Glass Is Different from Regular Glass

Many people assume that metro train windows are similar to those used in buses or cars. The reality is quite different.

Size and Scale

Metro coaches are large vehicles, and their glass panels reflect that scale. Duratuf Glass produces glasses as big as 1.83 metres by 2.6 metres for buses, and metro applications often require similar or even larger dimensions.

Impact Resistance

Metro trains operate in dense urban environments where objects can strike the glass — from stones thrown from trackside to birds and debris. The glass must absorb these impacts without shattering or compromising passenger safety.

Pressure Resistance

When metro trains pass through tunnels at high speed, they create pressure waves that stress the glass. Metro coach glazing must withstand maximum excess pressure of 2900 Pa and maximum depression of -6200 Pa in case of shock waves.

Optical Quality

Train operators must be able to see signals and track conditions clearly in all weather. The windshield must not distort colours, especially signal colours like red, yellow, and green, ensuring accurate visibility and safe train operations.

Vibration and Fatigue

Metro trains experience constant vibration from the track. The glass must withstand fatigue loads of ±1605 Pa without failure.

Fire Safety

Metro coaches use fire-resistant materials throughout. Glass components must meet stringent fire safety standards like DIN 5510-2.

Types of Metro Glasses We Manufacture

Duratuf Glass manufactures a comprehensive range of metro glass products for various applications.

Driver Cabin Windshields

The driver cabin windshield — also called the front windscreen — is the most critical glass component in a metro train. It provides the operator with the visibility needed to drive safely, read signals, and respond to track conditions.

Our driver cabin windshields are made from laminated safety glass, typically with thicknesses ranging from 12.5 mm upwards depending on the specific requirements. The glass is bonded to the cab structure using high-strength adhesives and meets international standards including EN 15152.

Key Features:

  • Laminated construction for impact resistance
  • High optical clarity with no colour distortion
  • Anti-fog and anti-scratch coatings available
  • Heated variants for cold-weather operations
  • Complies with EN 15152 and UIC 651 standards

Passenger Side Windows

Passenger side windows are the large glass panels alongside the seats in metro coaches. These windows provide passengers with views of the city, natural light, and a connection to the outside world.

Our side windows are manufactured using laminated or toughened glass, depending on the specific requirements of the coach design. The glazing material must comply with Indian standards like IS 2553 or equivalent international standards.

Key Features:

  • Available in flat and curved configurations
  • Laminated or toughened options
  • UV protection to reduce heat and glare
  • Scratch-resistant surface treatment
  • Complies with IS 2553 and EN standards

Interior Glass Partitions

Modern metro coaches often use glass partitions to separate different sections — such as dividing the driver cabin from the passenger area or creating separate zones within the coach.

Our interior glass partitions are typically 5 to 10 mm thick and made from toughened or laminated safety glass. These panels offer the necessary resistance for years of use in high-traffic public transport environments.

Key Features:

  • Available in various thicknesses from 5mm to 10mm
  • Toughened or laminated construction
  • Custom sizes to fit any coach design
  • Fire-resistant options available
  • Complies with CEN/TC 256 standards

Door Glazing

Metro coach doors often incorporate glass panels for visibility and aesthetics. Our door glazing products are manufactured to withstand the frequent opening and closing cycles while maintaining safety and optical clarity.

How Duratuf Metro Glasses Are Made

Material Selection

We use premium-grade float glass as the base material. The glass is carefully selected for optical clarity, minimal distortion, and consistent thickness. For laminated products, we use high-quality PVB interlayers that bond the glass layers together.

Cutting and Shaping

The glass is cut to the required dimensions using precision cutting equipment. For curved glass panels, the glass is heated and bent to the exact curvature required by the coach design. Duratuf Glass has extensive experience in producing both flat and curved glass products.

Lamination

For laminated metro glasses, the windshield is created by bonding multiple layers of glass with PVB interlayers under heat and pressure. This lamination process creates a single, strong unit that holds together even when impacted — the glass may crack but the fragments remain bonded to the interlayer, preventing injury.

Toughening

For toughened glass products, the glass is heated to high temperatures and then rapidly cooled. This process creates compressive stress on the surface and tensile stress inside, making the glass much stronger than ordinary annealed glass. When toughened glass breaks, it shatters into small, relatively harmless pieces rather than sharp shards.

Quality Control

Every metro glass product undergoes rigorous quality checks — including optical clarity tests, impact resistance tests, pressure tests, and dimensional verification — before it leaves our facility. Our glass products are manufactured in accordance with ISI standards, and the complete process is carried out under controlled conditions to ensure homogeneous and consistent quality.

Standards and Compliance

Metro glasses must comply with a range of national and international standards. Duratuf Glass ensures all our products meet or exceed these requirements.

  • IS 2553 — Safety glass specification for transport applications
  • IS 2835-87 — Flat transparent sheet glass
  • IS 2553 Part 1 — Safety glass for general purposes including railway applications

  • EN 17530 — Railway applications — Interior glazing for rail vehicles
  • UIC 651 — Strength requirements for locomotive cabs
  • DIN 5510-2 — Fire safety in railway vehicles
  • CEN/TC 256/WG 49 — Glazing for rail vehicles
