One thing to do to existing facilities. Just a rough sketch and
a small scenario.
Allowing track 1 to be both 'EWL EB' and 'NSL alighting' only.
Track 2, middle track that is, to be 'NSL boarding and alighting'
only. Track 3 to be 'EWL WB' only.
Taking zone A as platform 1, zone B as switch over from EWL EB
to NSL, and zone C as platform 2.
Train numbers in this scenario starting with 0 are NSL trains.
Starting with 1, EWL trains.
Train 001 pulls into zone A, alights passengers. 1.5 minutes
behind train 002 pulls into zone C. Train 001 pulls out of zone A,
goes into zone B, train 002 remains in zone C, picks up passengers
and departs for Marina Bay, then train 001 pulls into zone C from
B, and picks up passengers, then departs. Train 101 would pull into
zone A as train 001 enter zone B. Train 101 picks up passengers,
exits zone A into Clementi direction, 1.5 minutes later, train 003
enters zone A, drops off passengers, exits zone A into B. Train 004
enters zone C, drops and takes in passengers, while in the same
time train 102 enters zone A and takes in EB passengers, while
train 004 exits to let train 003 enter zone C...
This can be applied to normal hours, not only peak.
Why let one train go to the middle track, from NSL to EWL EB
then to middle track, then turn back to NSL? This acts as an
invisible turn-around facility, without having the train
operator walk from end to end when the train is in the
platform (or having operators waiting at both platform
ends), wasting operation time!
By routing a train to the middle service track at the eastern
end of JUR station, the line can be clear for the EWL EB trains to
continue service. NSL can maintain 2 minute frequency.
