If Jack Casterella got lectured by Adele Arakawa about the delaying the departure of his train, it was no one's fault but his own.

That’s because he was all alone in one of the trains between the terminals at Denver International Airport last Wednesday, and has a pretty epic photo to prove it (disclaimer: he says Adele wasn’t the announcer during this particular train experience, so she couldn't have actually lectured him).

Casterella said he took the photo just before midnight – and wants to book his next flight at around the same time so he gets another solo experience.

“I am a sucker for those sounds and scripts on the train, and when we got the B, I voice-mirrored the ‘hold on please, we are approaching the station for all B Gates,’” he said in a message to 9NEWS.

All in all, it sounds like a pretty cool experience – especially if you’re not a fan of the opposite situation, which consists of trying not to make awkward eye contact in a packed train.
