“I’m not nearly as attractive a travelling companion as the one who just left.” – Who is the speaker?  Who left?  What did the speaker mean by this statement?

The speaker of the above line is the second co passenger of the blind narrator, who boarded the train at Saharanpur.

The girl who got into the train at Rohana and travelled with the narrator till Saharanpur had just left.

The girl got down from the train at Saharanpur and the new passenger entered the compartment. The beautiful eyes of the girl caught the new Traveler attention. He tried to initiate a lighthearted conversation with the blind narrator by saying that the narrator’s previous co-passenger was far more attractive than him. With this statement he broke into the narrator’s reverie.
