I think Ministry of Tourism should be more active in this aspect.I was told that the Viaduct in Switzerland......."Landwasser" or some name,the Railways which looks over the operation is associated with U.N.E.S.C.O and is regarded as "World Heritage Site" or somthin like that :) I think India has so much to offer,be it mountains,beaches,deserts,snow,waterfalls......the flora and fauna from North to South from East to West has to much potential and can be taken in the best ways possible to showcase Brand India with both Railways and Tourism being primary stakeholders.
