1. What's with the red cables being installed throughout the underground
stations and tunnels (on wall mounted racks)? New signalling?
Associated with this cabling seems to be amber lights in the tunnels
and extremities of platforms that go out when a train is approaching.
What function do these serve? And what do the funny looking boxes
on the track beds with arms that drop down and go "clunk" do? And will
all the old cables lying completely disorganised on the track beds
at the underground stations be removed?
2. At the northern end of platform 5, Wynyard, there appears to be a room
opposite the platform. There are about three horizontally slatted
grills and a pair of doors that open above the track bed to indicate
its presence. Air ducts seem to enter the room, as do signalling cables
What is this room?
3. At the northern end of Redfern Station, on the western side, a tunnel
heads south and dives underneath the road bridge, disappearing under
platform 1. Where on earth does this tunnel go? I've never seen trains
enter or leave it. It's not marked on the maps and yet it is electrified.
4. On every staunchion in the Cityrail network is a yellow marker with a
code on it like "SW2+253". The 2+253 I've worked out is the distance
(2.253 km) from the NSW rail network zero point - the northern end of
the country platforms at Central. But what do the letters mean? Every
track seems to have different letters (e.g. CE, CI, CO, ES, SW, NS...).
Is there a list of all these?
Anyone know the answers?
PS. The closest-to-zero marker I've seen is on the Central Electric lines,
SW0+004. What's the furthest-from-zero??
Cheers,
Brendan.
