INFRASTRUCTURE SEGMENT REVIEW AGGRESSIVE FOCUS ON RESULTS INFRASTRUCTURE SEGMENT PERFORMANCE 8 The infrastructure segment provided  13 percent of Lindsay’s revenue in  fi scal 2014 compared to 9 percent in  fi scal 2013. Operating income was  $3.5 million compared to a loss of  $0.8 million the prior year, driven  Lindsay’s patented QuickChange  Moveable Barrier (QMB ® ),  commonly known as The Road  Zipper System™, is one of the few  ways to effectively and safely manage  congestion at a lesser investment  than that required to build new roads.  The QMB system provides a way to  divert traf fi c around construction  areas or work zones, increasing safety  for work crews and motorists alike.  On a permanent basis, the QMB  is used to vary the number of lanes  available to accommodate rush-hour  (tidal) traf fi c  fl ow, thus permitting  more ef fi cient use of available  roadway. More than 200 Road Zipper  Systems are in use in the U.S. and internationally. Infrastructure segment  revenues increased  20% due to significantly  increased sales of road  safety and rail products. The Company made signi fi cant  progress in infrastructure pro fi tability  in  fi scal 2014 through both revenue  increases and expense management.  The infrastructure sales team was  expanded and executed a more  aggressive, structured sales process  leading to expanded market share in  road safety and railroad products. For  road safety products, each state has  its own quali fi cation requirements for  vendors and products. We were able  to expand our geographic footprint  and make inroads in getting key  products quali fi ed in many more  states during the year. Lindsay’s infrastructure segment is  an international group of companies  producing a wide range of products  that aid in roadway maintenance and  transportation safety. We manufacture  moveable road barriers and barrier  transfer machines, energy-absorbing  crash cushions, specialty barriers for  work areas or construction zones,  road marking materials, railroad  signaling structures, and other safety- related products. Lindsay’s roadway  infrastructure products are sold  through 35 dealers in the U.S. and 35  international dealers, while railroad  products are sold directly to the major  railroad companies in the U.S. by higher sales volume. Operating  margins increased to a 4.5 percent  pro fi t in  fi scal 2014 from a 1.3 percent  loss in  fi scal 2013 due to higher sales and a mix shift to higher margin products. The innovative TAU Tube crash cushion was designed for use in tunnels.
