My initial plan to go down boon lay is to catch SBS8962Y on 193, who knows, later another K230 came on 193 and B9TL. Which on the trip I snapped, 8325L and 7456Z was back to back. SBS7456Z is the first ADD to do sv193, before it gets Leyland/Volvo Olympian 3 Axles, it already had B9TL as a cameo.
SBS7456Z went off service and parked in Boon Lay Int, I decided to observe until 8pm, it didn't move at all at the parking lot. After I left, another bus fan SMS me that it is doing 241.
