Neither in my 41 year career have I seen such professional videography - I salute you more good sir! infact, I salute you both, videographer and Mr. Rajamiya the good commenter sir! Love from Gulistan!!
Diamonds are common in railways throughout the world. What makes the diamond complex seen in the video unique is that each of those four individual diamonds are what's called in North American railways as “OWLS” (One Way Low Speed). These are diamonds in which one of the two crossing routes travels on the flanges of its wheels when crossing the rails of the other route. As its wheels approach the other route's track a floor beneath its flange path rises and raises the wheels by their flanges until the bottom of the flanges are the same height as the railhead. Meanwhile, the other crossing route is often able to cross the diamond at track speed since it's doing so on an uninterrupted tread bearing surface. This is one kind of effort to reduce the stresses to track and railway vehicles, such as brake shoes dislodging, when crossing diamonds. But it only accomplishes that for just one of the two routes. Thus the name 'One Way Low Speed'. Additionally, because the surface contact area of the flange bearing wheels is less than that of tread bearing wheels, its causes a groove or rut to be carved into the other route's running rails with perhaps some raised surfaces along the edges. The train in the video was on the continuous tread bearing route yet due to the grooves across its running rails a clickety-clack sound could be heard. While the voltages may be the same for the two crossing routes with overhead power lines, the contact of the pantograph to the power line is intended to be continuous, without interruptions, which create unwanted forces. For junctions of the power lines, as with turnouts, the stress may be minimal. But for diamonds, especially blunt angled diamonds, sudden, abrupt forces are unavoidable. That is likely why the locomotive lowered its pantograph some 50 meters or less before its pantograph crossed the first intersection of power lines. The momentum of the moving train, with its low frictional forces that make railways so effective, allows the train to coast along until the locomotive is clear of the diamonds before raising its pantograph. Aside from the lowering then raising of the pantograph, the slow speed of the train may simply be due to the designated speed assigned to that portion of track, independent of the diamonds.
India has atleast 3 Diamond lines that I know off , I believe they are in Delhi, Nagpur and one is on either Tamil Nadu or Kerala. Unless you meant Double Diamond.
Nice video. I guess the other two tracks are meant for freights coming from Itarsi side, and heading towards the Ajni freight yard. Isn't it?? Are the lines still operational??
This one you 've taken from outside the train (from the tracka) unlike the other Diamond crossings videos which are taken from the train. Anyway thanks.

Very Nice Bro
Diamond crossings in India are at two places. One is Nagpur and another is at Guntakal, AP.
Nice UA-cam Clip....? Where do all for track run to...? What are the average number of coaches a locomotive will pull...?
nice coverage!
