If we are talking about Britain, there were trams, the underground, buses and railways in the cities, but in the countryside only buses and some areas had trains. Most people did not have cars, you walked or biked if you did not have the money to travel on transport. You could also go on coaches to visit, some places
There is no such thing as a "trasport number".
