Continued fron the link above:
As a student studying at Admiralty Sec,I use 904 regularly.To
reach school on time,the last bus is SMB3068X which arrives at
6.56-6.58am every morning.The bus after that would be SMB3066B
followed by SMB3070M(there are is late start day every
Wednedsday).SMB3066B would arrive at 7.05am and there is a choice
on whether to board it or not as it would be on time but sometimes
due to delay you would be late which is why on other days except
Wed i would have to take 913/964 if i am running late.
Early last year when SMB3067Z-3069T was undergoing
repainting,other old livery bus replace them and one of them was
SMB3057C.If any of you know other buses that replace the repainted
buses last year please pot them here.*There was also a 13series Man
a22 replacing them
