yes too many curves.
but if one goods and one passenger are timed for crossing. let goods start at sklr and passenger at subramanya. now if goods fails before crosssing the passenger, the damage is minimum.
but if goods fails when nearing the passenger crossing at one of the 5 between stations then disaster.
but this is rear. risky but for more...
more... trains this risk needed.
Also the main loco only controls, they can brake if required isn't it. when going down they can brake. sir when coming up too they can brake if something is wrong wit rear bankers?
sir also pilots are there in bankers so they can take control of their locos if lead loco controls fail. they can override and control train sir? else then bankers are just pushing or braking with no control?
