Ahh, the joys and delights of England's green and peasant land!
But we are deceived as we take to the air Google-wise in 2014!
Once upon a time United Counties ran the buses via Loughton and The Shenleys, buses like this, running light near Ashton (hence Sywell on the blinds!). If you are extra specially observant, you can see bits of West Coast Main Line electric string gantries (in cutting) to the right of HBD's nearside lights:-
Services have been revised, re-organised, shuffled and re-tendered and a detailed route history is outwith fbb's experience. Let us limit recent omnibological traumas to the knowledge that the current holder of the Milton Keynes main operator (poisoned?) chalice is Arriva.
And, multiple network revisions later, the buses via Shenley have all gone green again ...
Before fbb gets stroppy comments, let the record show that Shenley is also served by mega circular routes 24/25 hourly in each direction and hourly 28, none of which are electric!
