Oh dear, If the new system lets up trains though before down trains,
Hillside will loose quite a lot of money on fines. Trains are scheduled
(during the 20 min frequency period):
Down HDB xx:17 - ROS xx:20
Up ROS xx:18 - HDB xx:21
As you can see, trains are sched in both directions at the same time on
the single track. Currently down trains use the single line first,
crossing Up trains at Rosanna Junction. This works out fairly well,
travel time is approx 2 mins between those two stations, and up trains are
usuallu only 1 min late ex HDB.
