When any bus I've got on states Loughborough Junction its always gone well beyond, to the stop two stops before the Police Station, so its probably worth hanging on, as its about a 10 minute walk or less to Brixton Town Hall. I've also got on P4's saying Dulwich Village only for that to be changed to Brixton shortly afterwards when I've still been on it.
Personally I would take a wait and see approach. You can always pick up another bus in Dulwich Village to Brixton - think its the 37 or 67- I'll check so there are other options.

However if you work in Brixton area you are totally reliant on the P4 hence no wonder people get a little agitated when it doesn't work out.

The roadworks and traffic light arrangements in Dulwich Village are a nightmare- must be a 'lets spend the money before the end of financial year thing' as surely it would have made more sense to do these works in the Easter hols when traffic would be lighter. one for the parliamentarians surely ie a guaranteed rollover to the next financial year for road monies provided its spent by the end of the Easter Holidays or beginning of May' etc etc- should enable cost efficiencies in other areas, and as we know the pressure to spend within this time doesn;t always permit the best procurement decisions to be made.

And why are Conways the only (seemingly) traffic works company around- do they win all the local authority contracts these days?
