We are going to attempt the challenge for the first time in November / Dec when according to the TFL Journey planner a full service is operating every Saturday ( I assume for Christmas shopping, no engineering works )
Also Olympia trains are supposed to be running frequently these dates
A couple of questions surrounding this if any experts here happen to know the answers..
1. Is this true it will be a full service on Saturdays?
2. Do Guiness count weekend attempts? I read somewhere they do not, which seems a bit bizarre fi the whole network is open.
3. Any more info on the fabled Olympia services..
Our route of course is secret

Thanks!
