This has probably been discussed many times, but I couldn't find any such posts...

I'm with 3 and have practically no service on the train between Honor Oak Park station and New Cross Gate. I'm wondering if everyone else suffers the same and also if there is a provider that does have decent service along this train line?


Obviously the location of the cell towers and the fact that the tracks are basically in a valley surrounded by residential housing will kill reception. But since we're unlikely to get wifi on-board in the next 2000 years, it would be nice if at least one mobile operator had a viable option for commuters.
