'Saturday 4.50pm. On Melbourne's Punt Rd, bus brakes squeal and huff. The 246 hits a standstill at the Bridge Rd corner. There's a momentary pall of silence on board — only the indicator click-clacks. The bus rests low on its suspension and seems to sigh. I slide across to the window side of my seat and brace myself. I expect noise, heat, irritation. I'd forgotten about the train lines closing for works.' (Introduction)
