He said, “The passengers were facing inconvenience of constant light from outside and external heat during the summer season affecting the efficacy of internal cooling too. This problem existed on a pan-India basis.”

The official said that for the first time in Indian Railways, Eastern Railway has evolved a solution to the curtain problem.

The official said that the Eastern Railway has introduced Polymer Dispersed Liquid Crystal (PDLC) based “smart switchable window” in the First AC coach of the Howrah-New Delhi AC Special, earlier known as the Rajdhani Express.

“This technology enables passengers to press the switch to make the transparent window glass non-transparent and vice versa,” he said.

“The newly installed window glass based on this technology will help the passengers enjoy privacy whenever they want and will also cut the ultra-violet radiation through the window glass,” the official added.
