Products & Technology in Brief
Ab Ovo and Quintiq have implemented a scheduling system covering Swedish freight operator Green Cargo’s 433 locomotives and 1700 staff. It takes into account factors including working time rules, route knowledge, certification and salaries.
Four US Class I railways and Amtrak have approved the use of Standard Strength rails from Steel Dynamics’ Columbia City mill in Indiana. Testing is underway of alloy -enriched rails for use in Canada, and further export markets are expected to develop.
Testing at the CEF high-current laboratory in Lausanne has demonstrated that KAGO’s rail contact and mast clamps can withstand short circuits of up to 40 kA. The company’s Rail Attachment Box is designed to provide access to electrical connections to tram rails set in roadways or grassed track. Impact forces from road vehicles are transferred to the rail, removing the need for concrete embedding of the boxes.
