From what I know for 241, it's merely a swap of 2 ASD (180 430)
for 2 ADD (9100 9109) from 242. No changes to trip timings.
242 will have a small change on top of the conversion of 2 ADD to 2
WSD blocks.
Ya.. but nt sure they decide to increase trips during the peak hrs
for svc 241. Btw, actually I think svc 242 need the DD during the
peak hrs..
2WSD = 2 weekdays single deck?
