Well, not airport but I am a regular train traveller...and often enjoyed the....The exlerince is far more better than airport when you cover the long distances journey...it becomes a cool home away with Co passengers turning into families and it quite entertaining....in flight I see people generally occupied with their own stuffs and appears to be more mean and selfish...train coaches get a good happy playground
I find some train stations to be not unlike airports in that there's a collection of people all going about their own thing. I'm referring to the big ones in Europe that connect countries...they're very similar to airports I guess, and can be quite entertaining.
then u need to travel to Indian train..... but at your own risk 😉
Lol...oh yeah I have seen some video footage and a few documentaries...I think I'll pass on it...although it'd be an experience I guess. :)
