Given the order of the Stadler Flirt Akku on the Schleswig Holstein line, which is a Bi Mode Catenary/Battery mode Flirt, I would imagine as Battery density improves, the Stadler Flirts on GA will swap out the diesel for Battery technology. The range is currently only 80 miles but given battery tech is rapidly improving this should improve.
So on my line, Sudbury-Marks Tey where would a 755/3 charge the batteries? I gather the original aim to run trains to Colchester Town has been put on the back burner but why not run to Platform 6 at Colchester North outside the peak. This would then recharge via overheads between Sudbury and Colchester North.
Oh and any idea when Sudbury-Marks Tey will see Stadler Flirts?
