Chiltern 'bubble' action

[Lucky_Tractor]

Ok - I'll put my hands up to the fact that I have posted this question elsewhere yesterday. The thing is, I want to be pretty sure that it's running before getting up at silly o'clock and driving to Aylesbury.

So - my question is simple - is/ has 121 020 been in service this last week? I know the diagram for it; I just don't want to be bowled by a 165.

Thanks in advance,

Dave

You're pretty much guaranteed to have it running every Monday-Friday. Better luck in the morning in case it fails during the day ...
