Does anyone have experience of travelling on a bi-mode train? I'd be interested to hear how smooth the change-over process is.
I traveled on the Great Western new express trains and the switch over was seamless. As soon as engines switch off the pantograph rises and train able to depart seconds lather. It was a calling point where the switch over happend but goes without saying it doesn't need to stop to facilitate the changeover.
Not experienced overhead to diesel yet.
