As of my last knowledge update in September 2021, the “Vande Bharat Express” (also known as Train 18) is an Indian semi-high-speed intercity electric multiple unit train service introduced by the Indian Railways. The train is designed for efficiency, speed, and passenger comfort. While I do not have specific information about the use of Fiber-Reinforced Plastic (FRP) in the Vande Bharat Train, I can provide some general ways in which FRP might be used in modern train design:

1. *Interior Components:* FRP may be used in the interior of the train for components such as seat frames, wall panels, and other cabin elements. FRP can be lightweight, durable, and easy to clean, making it suitable for these applications.

2. *Exterior Panels:* FRP could be used for exterior panels and body parts of the train. FRP panels can provide good strength-to-weight ratios, which can contribute to the train’s overall lightweight design, energy efficiency, and speed.

3. *Roofing and Insulation:* FRP can also be used for the roofing and insulation of the train to help with thermal insulation, noise reduction, and maintaining a comfortable interior climate.

4. *Structural Components:* In some cases, FRP may be used for structural components that require a combination of strength and lightweight properties.

5. *Aesthetics:* FRP can be molded into various shapes and can be painted or coated to meet design and aesthetic requirements.

It’s important to note that the specific use of FRP in the Vande Bharat Train or any other train design can vary depending on the manufacturer’s design choices and objectives. For the most up-to-date and detailed information on the use of FRP in the Vande Bharat Train, I recommend referring to official sources or the manufacturer’s specifications.
