i really like these kind of overtakes by loop line....primary benefits are
=> It shows that goods train are the Boss of IR,even mighty rajdhani has to slow down when a goods is blocking main line
=>while slowly crossing we can closely observe the loco(railfan's delight) & if its BCNA then carefully we can read the seal on which product code as well as origin destination is written...so we can estimate which kind of commodity IR transports & what are the major freight loading unloading pt.
