Under what new name is the Lucknow–New Delhi Tejas Express being branded?

Following the acquisition of advertising rights, the Lucknow–New Delhi IRCTC Tejas Express is being branded as the "Sprite Tejas Express"; it is India's first corporate-branded train and exemplifies the railways' non-fare revenue model. Launched in 2019, this train covers a distance of approximately 512 km in 6 hours and 35 minutes; its branding offers the potential to generate additional revenue for the Railways through advertising and commercialization.
