We therefore negotiate large quantities of services and goods on the full international market. 

A few examples:

• The operation of all bus and railway services in the county
• Vehicles for the Metro and tram systems, as well as bus and commuter train services
• Complicated technical systems for rail services
• Information systems
• Maintenance and inventory of stations and bus stops
• Cleaning and property maintenance
• The design of timetables and information material
• Tickets
• Surveys and statistics
• Telecom and ADP services
• Financing

It is not always the contractor with the lowest price that wins a tender. It is often the experience of, and success with, similar assignments that is considerably more important.
 
All SL services, both bus and train services, have been tendered for in stages since 1993.
 
The procurements are made by each respective unit within the SL Group, but it is the board that makes the decisions about the major procurements.
