Thanks, but the web sites are as clear as mud! I tried doing a a journey planner for tues and it said 176 was running, yet Wikipedia says the route is run by Arriva; and the TFL site says Arriva (South) is on strike.
It's a shame TFL just can't publish a list of the routes affected.
Praying the strike isn't going ahead as I am disabled and can't use train and tube to get to work in Soho. This is going to be a £60 return taxi journey. Nice, just after Christmas.
