Thinking about it, those from Taman Jurong to Jurong East
(especially those transfering to buses/NSL) may prefer 49
extension, as there's only 98 (which is winding along Jurong
West/East Ave 1) and 178 (which has poor frequency and only plies
the outskirts of Taman Jurong). Especially important for Yuan Ching
Rd which only has 154.
Additionally, AYE will have workers at those construction areas
going to Jurong East... Now there's only 178.
I'm not sure if 49 from Jurong East to Jurong West St 42 will be
faster than 334 (most likely it won't), but it may also serve as an
alternative to the always crowded 334.
I will try 49's extended route.
