CLOSING THE GAPS IN TRACK DESIGN

Standard track with concrete sleepers and continuously-welded rail has already been laid on 7,000 km of line in China. Engineers are well on the way to solving problems of wear under exceptionally heavy traffic, but the key area of points and crossings remains a source of difficulty. Moving frogs to eliminate the gap have been installed experimentally between Beijing and Shanghai, and efforts are being made to reduce stresses due to differential expansion of track and structures on long bridges. Chinese Railways plans to minimise track maintenance problems at source by aiming for longer component life at the design stage; proposals for widespread mechanisation of maintenance work are also nearing fruition.
