I predict the BTL will join up with the Bukit Panjang LRT line
and travel down Upper Bukit Timah road.Main problem would be the
KTM bridge and Rail Mall along the narrow portion past
Assumption.
Unless they are going to build it through Dairy Farm,have it run
above and alongside the KTM track, past Jalan Asas estate, all the
way to Rifle Range Road and diverge off at the King Albert Park
region to perhaps move over the current canal.
Not going to be a walk in the park I'm afraid.
