[edit] Platforms

East Hills Turnback	Olympic Park balloon loop	Side platform on single bidirectional line	Side platform on double line
Island platform on double line	Three different platform types at one station

A diagram showing the different meanings of the word "platform" in the context of a railway station. The fictional station has
* 1 island platform (green)
* 2 platform faces/platform tracks (blue)
* 3 independently signalable platforms (purple)
* 4 designated platforms (red)

[edit] Stations with Turnbacks

Island Platform with Centre Turnback Siding - Martin Place

Track centres between the sidings are a wide 6.5m to allow crew and cleaners to walk safely between the tracks.

Station with two through platforms and a Centre turnback platform - Revesby - under construction.

At Martin Place the track centres are very wide, and no slews are required to make room for either the platform or the turnback siding, which are in any case all in tunnel. The advantage of a centre turnback, is that a train can enter or leave the turnback without blocking the opposite track. Compare this with the less satisfactory arrangement at East Hills.

[edit] Terminals

[edit] Access

1 - No Wheelchair access

2 - Planned Wheelchair access

3 - Assisted Wheelchair access
