Here we have a while host of working phone numbers +442072651062,
+442072651063, +442074806055, +442074806050, +442074806053, at this
beautiful little central London trainstation terminus. Best time to
call is during morning and evening rush hours. Evenings are perhaps a
little better as you get people wating around more than in the
mornings. Be warned though that this model of payphones does not ring
very loud.
