Yes,you you've got to extend the route, well of course you've got to put up, trolley poles every for about forty yards and then of course there was two lengths of trolley wire that had to go because as you know trolley buses used to have two arms, positive and negative supply and er, of course the bus had to come back er alongside the premiu the outward route, it come on, so you had four wires up there and the cost of copper wire was terrific so the motor buses were developed and we expenim experimented with the buses on, on extensions mainly but when the extensions were finished we then begradged because trolley wires were then beginning to wear out, rather than replace them they would convert a trolley route into a bus route, and erm because the erm, there was a lot of people hated to see the demise of the trolley buses because they were so clean and silent  and the buses came, you got the deal sloke and lumbering of the old engines, that a lot of people hated to see the trolley buses go but cos that was the, the reason that they went.
