Nepal will not allow nationals from third countries to travel to lndia by rail via the recently launched Kurtha-Jayanagar railroad after Indian officials raised a red flag, citing security concerns. Nepal and India share a porous border, which has been a hotbed for criminals and terrorist activities, and thus a Standard Operating Procedure (SPA) was finalised. SPA is a document outlining the procedures adopted for cross-border railway operations. You can contact Nixtour for more information and book cheap flight tickets to Nepal.
