That may or may not be correct.The cost of that would be similar, as would be converting it to a tramway
As craigybagel has so rightly said, it works well as it is, why change it? As far as I can see the most compelling fact based argument for changing the method of operation is “because it annoys a few forum members to see two members of staff on it”
I’m afraid I haven’t heard a convincing argument so far that the expenditure and inconvenience of changing the method of operation would be worthwhile or would result in a better service being delivered to society
All I & I think some others are saying is these & other similar decisions should primarily be the in the hands of the industry’s best experts & professionals & not simply devolved entirely to the trade union activists with a particular agenda.
