not considering waiting time
PSR to CTH is 27mins
BSH to CTH is 15mins
trains run faster during peak hours. however, that is only because
they stop at the stations longer due to heavier pax movement. so in
the end, the effective travel time remains the same. these are,
from observation, roughly defined as:
Mon-Sat, 7am-9am
Mon-Fri, 1pm-3pm
Mon-Sun, 6pm-10pm
Sat, 1pm-4pm
Sun, 10am-2pm
buses do run faster at night. in fact, most buses run faster after
10pm. and the last bus should be a breeze to take.
