242 wasn't the first and 225 wasn't the second. I believe the
first was 334. I remembered seeing DDs on this service as early as
1987/88, first using O305 followed by the LO2X until its
retirement. The second would be 240, using LO2X. Then came 242.
However, 242 may be the first and possibly the only
feeder to have DDs right from the start in 1990. Other feeder
buses using LO2X in Jurong include 243, 333 and 335 (I can't recall
if 331 had any). For O305, in Bishan, there's 410, in Eunos, sv.
385 and, according to the postings above, they were also used for
the Hougang feeders. Many LAs spent their twilight years on the
feeder services in CCK, Bedok, Tampines and Pasir Ris. Services
include 300?, 302, 222, 359 and others.
Back then quite a number of feeders/townlinks using DD , such as
222 , 228 , 240 , 242 , 243 , 300 , 302 , 307 and many more...
