You are right, that did used to happen thank you for your vague memory, he did that and then got out and swing the trolley pole. The memories return post by post. Then he did the same before the tram moved off. Now was the bell a big push thing that was hit with the whole hand and a wire like the Routemaster attached to the ceiling ran through each saloon?I have a vague memory of the conductor turning the brake handle and I wondered why. Perhaps it was the conductor's job to apply the back brake at the terminus so that the driver could release the brake at the front.
