There's no K230 on 410 yesterday. Do not believe everything that
you dont see physically.
Was thinking the same thing too. I saw no K230 on the 3rd
slot...
Anyway... I wonder who is that person who put 8247D under HGDEP
SP. It did 53 today. =S
SBS 8236K on 163 (HGDEP SP)
SBS 3902D on 410 (AMDEP 70)
There are unseen reasons why 2 of a kind can breakdown
together, one after the other. 
Today, 24S bus SBS 0334M broke down while Off-Servicing to Bishan,
next bus 16A SBS 0414R also broke down while going
to Bishan. 17A bus SBS 0333R was forced to leave 20 minutes earlier
to help ease the larger passenger loads. At the bus stop opp. J8,
Next-Bus arrival system noted that next bus (18A) was 32 minutes
behind.
