The 37 and the P4 are surely the worst buses in the area but I have always found the 176 reasonably reliable. What is annoying is that 1. Buses wait ?to regularise the service? or as happened to me once, to allow the driver to pop into the newsagents opposite East Dulwich Station to buy a chocolate bar. 2. When stops are closed because of roadworks, for example, they used to set up a temporary stop nearby but now they just go to the next bus stop which is often quite a long way ahead.
