The 29-year-old "Piku" star, who hopped on the Suvidha Express from Mumbai Central yesterday, says love for travel, food and trains, is a common factor that binds her, Ranbir, and the "Highway" filmmaker together.

"Train journeys are very romantic. I think we all have travelled by train individually. And train, travel, food, restaurants and places are common things between three of us.

We are always talking about new places and travelling.

"We know travel is a very important part of Imtiaz's life and in the movies that he make. I am happy that media could share this experience with three of us. The idea was to have fun," Deepika said.

Ranbir, who gives the credit for the idea to Deepika said he enjoyed this new and unique way of promoting the film.

"When the idea was proposed, we all jumped at it. When you market a film there is a set pattern. But usually with Imtiaz he likes to break those patterns. In 'Rockstar', we travelled in a bus and media jumped at that. It's a very interesting idea," he said.

'Tamasha' will hit the theatres this Friday.
