According to JE route group...the 2 stops that 98A pass (the one
at AYE and outside Taman Jurong Shopping Ctr (Sheng Shiong)...can
be use for boarding and alighting..so lao aunty and ah gong can
wait for 98A to and at sheng shiong to do marketing 
they need not be empty, if there are passengers wanting to
board.
Service 98 covers the full route from Jurong East Interchange via
Jurong East Ave 1, to Lakeside Station, into Taman Jurong Estate
down to Jurong Port Rd, to Jurong Port area and loop back via the
same route in a vice-versa format.
Service 98A covers 3quarter of the route from Jurong East
Interchange via Jurong East Ave 1 to Lakeside Station and down to
Taman Jurong Estate...it then loops at the end of Taman Jurong
Estate via Yung Ho Rd, Corporation Rd, AYE and back to Yung Ho Rd
and has 2 additional stops (AYE and Sheng Shiong) that Service 98
does not cover..
If you are going to Jurong East Ave 1, Jurong West St 51, Lakeside
Station and Taman Jurong Estate, you can take either Service 98 or
Service 98A
If you are going to Jurong Port, Jurong Pier and Fishery Port Rd
area, you can only take Service 98.
If you are going to the Sheng Shiong Hypermart, u can only take
Service 98A.
To differentiate Service 98 and Service 98A, look at the bus..buses
that are plying the Service 98A route will have a "A" suffix on the
desto.
The buses alternate...one bus 98, then next one is 98A, then 98
then 98A etc. between 930 - 1630 and 2000 - 2400...
Service 98 operates between 0530 - 2400.
Service 98A operates between 0930 - 0030.
Service 98 and Service 98A is a FULLY AIRCON service.
