Why the heck did they build a level crossing in to a new piece of rail?A) Brolgan Rd will form an access to the PN Parkes Terminal but only a little local traffic would be coming from the West over this LXing, so lights, bells and booms is probably adequate, although I'd hate to be one of the locals heading into town and get stuck at the crossing while an 1800m long train slowly pulls in in/out of the yard.
B) What struck me is why did they build the level crossing in mass concrete?
They have created a fixed point that can't be lifted, let alone tamped.
C) Also, the track will develop a hole on each side of the crossing.
With low speeds it won't happen overnight, but it will happen, and it will be very difficult to do anything with.
D) Let's hope an underground spring doesn't decide to break to the surface right there!
According to photos in "Track & Signal" magazine (V23 N4 p36) , turnouts between the yards and main line are highspeed types, say 1 in 18 V-crossings. Entry speed into the yard may be restricted due to low speed signalling, while departure speed is not restricted in any way. No manually operated Ground Frames
So departing trains are quicker than normal over the join. There are no sharp Reverse Curves.
At Glenfield tunnel there massed concrete in the tunnel adjoins ballasted track. To provide a smoother transition two addition checkrails overlap the concrete/ballast joint, providing a smoother join. B) This seems to be done at Brolgan Road West,
C) The distance between the Level Crossing and the nearest two turnouts maybe about 20m, leaving some room to tamp the ballasted track, while leaving the concrete slab alone.
D) There are some large new culverts quite close to the Brolgan Road Lxing, which might be used to divert any spring water.
E) Overall, the tracks near Brolgan Road look to be carefully designed.
