What is it about travel that is so.. magnetic?So much so that Tennyson's 'Ulysses' felt the whole unexplored world always beckoning to him,never letting him stay idle? Even the common portals of a journey - a train station,for instance - are fascinating,even if you are not a traveller yourself.There are the expected sights - stray dogs,vagrants,porters,policemen,loiterers,who blend in with the constant smell of urine,the blaring television screens fighting for attention over the announcements of arrivals and departures of locomotives.But they never get boring.You look at these people crowding the platforms,the ticket counters,the waiting rooms,the overbridges,pretty much everywhere...and there is a plethora of emotions,ranging from hope to despair.Lone travellers descend and look around for porters,others alight to embrace their loved ones,and still others arrive in groups,fresh and renervated from shared experiences.The sense of discovery,of belonging and being alone at the same time is overwhelming.These are but few of the delights offered by the promise of progress.
