I'm genuinely struggling to think of a reason why they would even bother reinstating the line. To me, it seems like a complete waste of money, plus I can't see the demand being high enough to make it financially viable.

Sure, it's going to probably knock 15 or so minutes of the journey time compared to taking the bus, but is that worth the tens of millions it's going to cost?

Plus, I personally find taking the bus much more convenient, there's no need to traipse to a train station, just to the end of the street.
