- A tram (trolley) or trolleybus is something else.
It was primarily an urban vehicle so that, on the paved roads, the small wheels were not a handicap. In any case, the axles would normally be sprung. It was typically used by market fruiterers and greengrocers but commonly also by coal merchants. These would have a headboard to stabilize the front row of sacks which then held up the next and so on. The deck was at a good height for taking the bags onto the coalman's back and there was no protruding rear wheel to obstruct his access to them.
Many ended up with rag and bone merchants who were likely to add side and tail boards to keep their purchases aboard.
The largest and sturdiest trolleys were those used with lift vans.
As in many fields, as time went by, people used the word without understanding its detailed meaning so that it became applied less precisely and other configurations were given the name and some trolleys were known by other names. For example, the electric milk float is more a trolley than a float, as is the brewer's 'dray' seen at horse shows.
