This picture has been taken ages ago really when there was track work along Central to Circular Quay. Taken with a normal DC (Sorry about that, I don't have the talent in photography so I didn't bother to buy myself something expensive.) Anyway, here is 2 exact same type of bus going on the same routes lining up together! (Well, not actually. There is a little difference in their appearence (Don't' tell me it's their number plates), can anyone find it?) Please don't ask me if I am taking this photo on the road. Yes, I did, but I took it within half a second when I was crossing the road, so please don't scold me.

I guess the windows of left one is rounded angle but the right one is not... Am I right?

I think is the different curve on the bus head. The left one seems to have a more curve head-part. (Or maybe it is just the angle's problem.. or something like that )

#1523 without "Sydney Bus" logo beside front door
#1534 Red line on front of the bus disappeared

both VOLVO B12BLE with Custom Coaches CB60 body

9042Volvo is correct. In fact, the only difference between the two is the color and the sign. (Just something out of topic: I don't really like this type. It gets really noisy on hot days like HK old B9TL, slow, and it has poor maintanence in the inside. The government never maintain their buses well.)

Well actually i don't think that the B9TLs have a noisy engine sound..
They have already utilized a D9A or D9B engine which MUST be better than those like B10Ts and Dominator 6x2...

it's not the problem of the engine, but the radiator. It's really noisy when in summer.
