Railways or Railroads?
Contrary to popular belief, not all rail businesses in the USA are referred to as Railroads. It is true that most of the major national carriers are so named, but there are many smaller concerns that use the name Railway; in the past, the proportion of these was even greater, perhaps as many as half the total number of companies. For this reason, as well as for consistency with my other pages, I shall use the term railway here, except when referring to the actual name of a company. There are a few other differences in vocabulary between British and US usage; see the Glossary.
Because of the size and complexity of the subject, the railways of the USA are dealt with in a series of separate pages, indexed below.
