In the following tables an attempt has been made to group 
together certain railways which clearly belong to the same 
type, and to show the mileage and traffic and cost statistics 
as developed in each group. These groups are made up as 
follows : 
I. "Thestreet railways of the whole state. 
II. The Boston Elevated Railway Company, an urban and suburban 
road serving the densely settled district of Boston and the cities 
and towns immediately surrounding. 
III. A group of roads distinctly urban in their character, and to only a 
limited extent serving detached suburban districts. 
IV. A group of roads wholly interurban in character, connecting or pass- 
ing through towns where the local traffic amounts to very little. 
A group of roads of the mixed type, urban within large towns with 
considerable local travel, suburban connecting detached suburbs 
with the central district, and interurban connecting towns of more 
or less population with one another and with the larger central 
district.
