A branch line is a secondary railway line which branches off a more important through route, usually a
main line. A very short branch line may be called a spur line. Branch lines may serve one or more industries, or a city or town not located on a main line. Branch lines may also connect two or more main lines.
Industrial spur
An industrial spur is a type of secondary
track used by railroads to allow customers at a location to load and unload
railcars without interfering with other railroad operations.
Industrial spurs can vary greatly in length and

capacity depending on the requirements of the customer the spur is serving. In heavily industrialized areas, it is not uncommon for one industrial spur to have multiple
sidings to several different customers. Typically, spurs are serviced by local trains responsible for collecting small numbers of railcars and delivering them to a larger yard, where these railcars are sorted and dispatched in larger trains with other cars destined to similar locations. Because industrial spurs generally have less capacity and traffic than a mainline, they tend to have lower maintenance and signaling (train control) standards.
Before the rise of the long-distance trucking in the early 1930s, railroads were the primary means of transportation around the world. Industries of the era were commonly built along railroad lines specifically to allow for easy access to shipping. Short (under a mile, oftentimes only several hundred yards) industrial spurs with very small (under ten car) capacities were a common sight along railroads in industrial and rural cities alike. As

and roadway technology improved throughout the early and mid-20th century, most low volume industry spurs were abandoned in favor of the greater flexibility and economic savings of trucking. Today, railroads remain the most economical way to ship large quantities of material, a fact that is reflected in industrial spurs. Most modern day spurs serve very large industries that require hundreds, if not thousands, of carloads a year.

Canada
Much of Canada's branch line history relates to large rail transport conglomerates (such as the
Grand Trunk,
Canadian National, or

) which would acquire formerly independent
short line railways for use as branch lines, with the short line often continuing to exist as a subsidiary. For example, when the Canadian Pacific acquired the
Algoma Eastern Railway (a short line) in 1930,
it soon after abandoned much of the Algoma Eastern mainline, but retained sections close to Algoma Eastern–Canadian Pacific junctions as short branch lines or spurs.
The ''National Transportation Act'' of 1967 provided government subsidies for branch lines.
Western railway development in Canada worked in concert with land settlement and cultivation, as pioneers were settled near railway lines, often on land the railways had owned. However, by the mid-20th century, railways began neglecting lines in western agricultural regions. This was historically driven by factors such as the
Crow Rate, which regulated the price railways could charge for shipping grain. Railways had little incentive to invest in rural

branch lines, but were legally unable to abandon them under the ''National Transportation Act'', which also did not provide a subsidy for grain transport, and instead allowed railways to absorb branch line subsidies freely without making effort to improve the profitability of the lines.
The term "grain-dependent branch lines" began being used as early as 1978 to refer to the special case of these branch lines in agricultural areas whose viability depended on the economics of grain transport.
The ''
Western Grain Transportation Act'' of 1983 addressed this case specifically, but was repealed in 1994 in the wake of the

The North American Free Trade Agreement (, TLCAN; , ALÉNA), referred to colloquially in the Anglosphere as NAFTA, ( ) was an agreement signed by Canada, Mexico, and the United States that created a trilateral trade bloc in North America. The ...
and budget-balancing initiatives in favour of a one-time payout by the federal government directly to farmers, to arrange transport of grain themselves. From the mid-1970s to the late 2010s, more than of Prairie branch lines were abandoned or had a discontinuance of service.
