Rail Business Intelligence was a fortnightly subscription newsletter for senior managers, investors, lawyers, contractors, consultants, local authorities, trade unionists,[1] manufacturers and service providers working in the United Kingdom's rail industry.

[2] After 23 years and 554 issues the final print edition was produced in March 2018,[3] and Railway Gazette Group's UK news is now published online[3] as Rail Business UK.

[4] Initially conceived as a short-term project to provide inside information for financial, legal and commercial organisations taking part in the privatisation of British Rail, the Railway Gazette International newsletter saw circulation continuing to expand after the 1997 general election, and in 1998 the title was changed to Rail Business Intelligence to reflect its ongoing role in the UK's privatised rail market.

[3] It was published every second Thursday as a printed magazine and also in PDF electronic format.

[5] The newsletter was part of the Sutton, London based Railway Gazette Group, which includes publications such as Railway Gazette International, Metro Report International and RailwayGazette.com.
